Geek Notes — Champagne superlatives and exceptions (Part II) Vallée de la Marne

Amber LeBeau in Champagne, Geek Notes, Wine Knowledge

Published on January 14, 2020

Welcome back! To get the lowdown on the series check out Part I where we explore the exceptions of the Montagne de Reims. In Part III and IV, we’ll check out the Côte des Blancs and the Aube/Côte des Bar.

As for today, we’re heading to the Vallée de la Marne.

The Marne river flowing past Épernay in the early 20th century.

If you’re one of those folks who “know enough to be dangerous” about Champagne, you’ll peg the Vallée de la Marne as the Pinot Meunier corner of the holy triumvirate of Champagne. However, as we noted in part one, neatly pigeonholing these regions with a single variety cuts about as deep as a butter knife.

To really start to “get” Champagne, you have to move beyond the superlatives (and the BS of so-called “Champagne Masters”). This requires looking at legit sources but also getting your hands on detailed maps.

Having good wine maps is an absolute must for any wine student.

Yes, you can find some online. For today’s journey through the Vallée de la Marne, this interactive map from Château Loisel will be useful. But sometimes clicking between computer tabs is annoying compared to a physical map in front of you.

I mentioned the Louis Larmat maps yesterday. But let me give you two more excellent options.

In the lower-right, you can see the start of the Côte des Blancs with the Grand Cru village of Avize noted.

Benoît France’s Carte des Vin. This is an entire series covering French wine regions–including a detailed map on La Vallée de la Marne.

Unfortunately, these maps are mostly only available in France. However, I was able to buy several when I lived in the US through Amazon for around $11-13 each. You will still need to pay international shipping. But buying multiples at once helps offset that a little.

Hugh Johnson and Jancis Robinson’s World Atlas of Wine is always a reliable resource. It will list many of the villages and show topographical details. The only negative is that it doesn’t highlight the 17 subregions within Champagne.

There are six in the Vallée de la Marne.

Grande Vallée de la Marne
Vallée de la Marne Rive Droite (Right, or northern, bank of the Marne)
Vallée de la Marne Rive Gauche (Left bank of the river)
Côteaux Sud d’Épernay
Vallée de la Marne Ouest (Western valley)
Terroir de Condé

Across the 103 villages of the Vallée de la Marne, it’s no shock that Pinot Meunier reigns supreme. The grape accounts for nearly 60% of all plantings.

The Marne river meandering by the premier cru village of Hautvillers.

As with many river valleys, frost is always going to be a hazard as cold air sinks and follows the rivers. Compared to larger bodies of waters such as lakes or estuaries, the relatively narrow and low-lying Marne doesn’t moderate the climate as dramatically.

That means that drops in temperature during bud break can be devastating for a vintage. A perfect example of this was the 2012 vintage.

This risk is most severe for Pinot noir. It buds the earliest followed soon after by Chardonnay. Then several days later, Pinot Meunier hits bud break–often missing the worst of the frost.

As we saw with many of the exceptions in the Montagne de Reims, the threat of frost in river valleys tilts the favor towards Meunier. It also helps that the grape is a tad more resistant to botrytis than Pinot noir and Chardonnay. This and other mildews thrive in the damp, humid conditions encouraged by the morning fog following the river.

Finally, while there is limestone throughout the Vallée de la Marne, it’s more marl (mixed with sand and clay) rather than chalk. Pinot noir and Chardonnay can do very well in these kinds of soils. However, Pinot Meunier has shown more affinity for dealing with the combination of cooler soils and a cooler, wetter climate.

But, of course, there are always exceptions–none more prominent than the Grande Vallée de la Marne.

In many ways, the Grande Vallée should be thought of as the southern extension of the Montagne de Reims. Its two Grand Crus, Aÿ and Tours-sur-Marne, share many similarities with its neighbors, Bouzy and Ambonnay.

Along with the “super premier cru” of Mareuil-sur-Aÿ, these south-facing slopes produce powerful Pinot noirs with excellent aging potential. Notable vineyards here include Philipponnat’s Clos des Goisses, Billecart-Salmon’s Clos Saint-Hilaire and Bollinger’s Clos St.-Jacques & Clos Chaudes Terres (used for their Vieilles Vignes Françaises).

Jamie Goode has a fantastic short video (1:55) walking through the two Bollinger vineyards. One thing to notice is that the vines are trained to stakes and propagated by layering.

Compared to most of the Montagne de Reims, the vineyards here are slightly steeper. They’re also at lower altitudes as the land slopes towards the river. However, in contrast to most of the Vallée de la Marne west of Cumières (the unofficial end of the Grande Vallée), the climate is warmer here–tempering some of the frost risks.

Also, the topsoils are thinner with the influence of chalky bedrock more keenly felt. This is particularly true in the eastern premier cru village of Bisseuil, which is planted to majority Chardonnay (66%) and only 6% Pinot Meunier. These grapes go into the cuvées of many notable Champagne producers. Among them, AR Lenoble, Deutz, Mumm and Gonet-Médeville.

Though Chardonnay is mostly a backstage player in the Grande Vallée, the premier cru Dizy (37% Chardonnay) joins Bisseuil as notable exceptions. This is the home turf of Jacquesson with Perrier-Jouët and Roederer also getting grapes from here.

Across the Grande Vallée, Pinot noir reigns supreme.

It accounts for nearly 65% of all the plantings among the 12 villages of the region. Here Pinot Meunier is a distant third with only around 15% of vineyard land devoted to it.

Meunier slowly starts to creep up in importance the further west you go. Here the soils get cooler and clay-rich with more sand. In the premier cru of Champillon, Pinot Meunier accounts for 31% of plantings and is an important source for Moët & Chandon.

Likewise, in its neighbor to the west, Hautvillers (the historical home of Dom Perignon), Meunier also accounts for around a third of vineyards. Of course, Moët & Chandon sees a good chunk of Hautvillers’ grapes along with Veuve Clicquot, Roederer, Jacquesson and Joseph Perrier.

The vlogger Ben Slivka has a 2-minute video of the area taken from a vista point near Champagne G.Tribaut.

Côteaux Sud d’Épernay

Across the river from the Grande Vallée is the city of Epernay. The hills extending south and slightly west make up an interesting transition area between the Vallée de la Marne and Côte des Blancs.

The chalky bedrock is closer to the surface, with far less sand than most of the Vallée de la Marne. However, there is considerably more clay (and less east-facing slopes) in the Côteaux Sud d’Épernay than the Côte des Blancs. The area is slightly dominated by Pinot Meunier (45%), with Chardonnay close behind at 43%. The city of Épernay, itself, is an autre cru with considerable Chardonnay plantings (60%).

There is also quite a bit of rocky–even flinty-soil in the Côteaux Sud d’Épernay. This is particularly true around the premier cru village of Pierry which was the home of the influential monk, Frère Jean Oudart.

Dom Perignon likely spent his career trying to get rid of bubbles. However, his near-contemporary Oudart (who outlived Perignon by almost three decades) actually used liqueur de tirage (sugar and yeast mixture) to make his wines sparkle intentionally.

Except for Pierry, all the villages of the Côteaux Sud d’Épernay are autre crus.

Another geeky cool thing about Laherte Frères’ Les 7 Champagne is that it’s made as a perpetual cuvee in a modified solera system.

However, there are many notable villages, including Chavot-Courcourt–home to one of Champagne’s most exciting wine estates, Laherte Frères.

While the plantings of Chavot-Courcourt are slightly tilted towards Pinot Meunier (51% to 44% Chardonnay), in Laherte Frères’ Les Clos vineyard, all seven Champagne grape varieties are planted. Here Aurélien Laherte uses Pinot blanc, Pinot gris, Arbane and Petit Meslier to blend with the traditional big three to make his Les 7 cuvée. This is another “Must Try” wine for any Champagne lover.

Further south, we get closer to the Côte des Blancs with thinner top soils leading to more chalky influences. Here we encounter a string of villages all paced by Chardonnay–Moslins (58%) Mancy (52%), Morangis (52%) and Monthelon (51%).

Going back towards the northwest, the soils get cooler with more marly-clay. We return to Meunier country in villages such as Saint-Martin-d’Ablois (80% Pinot Meunier) and Moussy (61% PM)–home to the acclaimed Meunier-specialist José Michel & Fils and a significant source of grapes for Deutz.

Vallée de la Marne Rive Droite and Rive Gauche

As we move west, the superlatives of the Vallée de la Marne being Pinot Meunier country becomes gospel. The cold, mostly clay, marl and sandy soils lend themselves considerably to the early-ripening Meunier. Accounting for more than 75% of plantings, it’s only slightly more dominant in the Rive Gauche than the Rive Droite (70%).

Because of its location, there are more north-facing slopes on the left bank of the Rive Gauche. Conversely, the right bank of the Rive Droite has mostly south-facing slopes. This topography plays into the narrative that the Meunier from the Rive Gauche tends to be fresher, with higher acidity. In contrast, those from the Rive Droite are often broader and fruit-forward.

However, there are several valleys and folds along tributaries running into the Marne. This leads to a variety of exposures in each area. But with these tributaries comes more prevalence for damp morning fog. Along these narrow river valleys, the risk of botrytis-bunch rot increases. While Pinot Meunier is slightly less susceptible than Pinot noir and Chardonnay, it’s still a significant problem in the Marne Valley. The 2017 vintage is a good example of that.

Though not about Champagne, the Napa Valley Grape Growers has a great short video (3:30) about botrytis. While desirable for some wines, it usually wreaks havoc in the vineyard.

Since there are few exceptions in these areas, I’ll note some villages worth taking stock of.

Damery (Rive Droite) – Located just west of Cumières, Damery is on the border with the Grande Vallée. With over 400 ha of vines, it’s the largest wine-producing village in the Vallée de la Marne. Planted to 61% Meunier, Damery is an important source for many notable Champagne houses. Among them, AR Lenoble, Billecart-Salmon, Joseph Perrier, Taittinger, Roederer, Bollinger and Pol Roger.

Sainte-Gemme (Rive Droite) – With over 92% Pinot Meunier, this autre cru is one of Krug’s leading sources for the grape.

Mardeuil (Rive Gauche) – With 30% Chardonnay, this village has the highest proportion of the variety in the Rive Gauche. Henriot gets a good chunk of this fruit along with Moët & Chandon.

Festigny (Rive Gauche) – A solitary hill within a warm valley, this village reminds Peter Liem, author of Champagne, of the hill of Corton in Burgundy. While there is more chalk here than typical of the Marne, this area is still thoroughly dominated by Meunier (87%). Festigny is noted for its many old vine vineyards–particularly those of Michel Loriot’s Apollonis estate.

Gary Westby of K & L Wine Merchants visited Loriot in Festigny where he made the video below (1:12).

Vallée de la Marne Rive Ouest and the Terroir de Condé

We wrap up our overview of the Vallée de la Marne by looking at the westernmost vineyards in Champagne. I also include the Terroir de Condé here because it seems like the classification of villages is frequently merged between the two.

Saâcy-sur-Marne (Ouest) – One of only three authorized Champagne villages in the Seine-et-Marne department that borders Paris. In fact, Saâcy-sur-Marne is closer to Disneyland Paris (50km) than it is to Epernay (70km). Going this far west, the soils change–bringing up more chalk. Here, in this left bank village, Chardonnay dominates with 60%.

Connigis (Ouest) – This is the only village in the western Marne Valley where Pinot noir leads the way. It just scrapes by with 45% over Meunier (41%). On the left bank of the river, Connigis used to be considered part of the Terroir de Condé. Today, Moët & Chandon is a significant purchaser of grapes from this autre cru.

Trélou-sur-Marne – Like all of the (current) Terroir de Condé, this village is overwhelmingly planted to Pinot Meunier (72%). However, it’s worth a historical note as being the first place where phylloxera was found in the Marne. This right bank village also helps supply the behemoth 30+ million bottle production of Moët & Chandon.

Kristin Noelle Smith has an 8-part series on YouTube where she focuses on notable producers of Champagne.

In episode three on Moët & Chandon (26:35), Smith touches on the impact of phylloxera in Champagne.

Takeaways

Though the Marne flows westward, the best way to think of the Vallée de la Marne is as a river of Pinot Meunier that changes as you go east. In the west, it truly lives up to the superlative of Meunier-dominance. This is because of the influence of the river and abundance of cold, clay and sand-based soils. But as we go east, and the river widens by the city of Épernay, the story changes considerably.

The part that “forks” north, the Grande Vallée, shares similarities with the southern Montagne de Reims. Here the terroir takes on more of the characteristics of the Pinot noir-dominant Grand Crus of Bouzy and Ambonnay. Whereas the south fork of the Côteaux Sud d’Épernay becomes gradually chalkier. This explains why you see more Chardonnay-dominant villages the closer you get to the Côte des Blancs.

Nailing these two big distinctions (as well as understanding why Meunier thrives in the Marne) is truly dangerous knowledge. Especially for your pocketbook!

So drink up and I’ll see you for part III on the Côte des Blancs!

Geek Notes — More Champagne with GuildSomm Podcast

Amber LeBeau in Champagne, Climate Change, Geek Notes

Published on December 22, 2018

This is the second part of our Geek Notes review of the GuildSomm podcasts with Ruinart’s chef de cave Frédéric Panaiotis. To catch up on the first segment, check out Geek Notes — The Process of Champagne GuildSomm Podcast.

GuildSomm podcast

In that post I also highlight why listening to podcasts is an extremely valuable tool for wine students. But not all podcasts are created equal or are worth your time. There have been many podcasts that I’ve picked up only to unsubscribe after a couple of episodes. Sometimes it is the overall production value that steers me away–noticeable mouth breathing, weird audio jumps between loud voices and whispers, distracting background music, etc. But usually, it is because of a lack of credibility in the content and people producing the podcast.

The world of wine is constantly changing and there is a lot of material to cover. Any podcast that is worth its salt needs to be backed up with solid research and commitment to accuracy.

One of the best wine podcasts, in that regard, is the GuildSomm podcast founded by Master Sommelier Geoff Kruth.

Some Background

Kruth founded GuildSomm in 2009 as a nonprofit that promotes education and development opportunities for sommeliers and other wine professionals. Though many people who aspire to be Master Sommeliers join and utilize the website’s materials, GuildSomm is not a part of the Court Of Master Sommeliers.

Podcasts, videos and recent articles are available to anyone for free on the website. However, access to the forums, study guides, maps, master classes and in-depth training material on topics like blind tasting require membership. For wine industry folks, the fee is $100 a year while for non-industry wine lovers it is $150.

Fun Things I Learned From This Podcast

Ruinart’s non-vintage blanc de blancs and rose.

Like the previous podcast, this episode (44:54) features a highly informative interview with Ruinart’s Frédéric Panaiotis. But the second half is a discussion with the acclaimed grower-producer Rodolphe Péters of Pierre Péters.

(1:29) The podcast starts with a description of the Montagne de Reims region of Champagne. This area, south of the city of Reims, has a unique horseshoe shape.

The topography creates a diversity of exposures in nearly all orientations (south, east, north, west, etc). This makes it hard to generalize the style of wines from its several villages–including 10 Grand Cru (Ambonnay, Beaumont-sur-Vesle, Bouzy, Louvois, Mailly-Champagne, Puisieulx, Sillery, Tours-sur-Marne, Verzenay and Verzy).

Panaiotis gives a nice overview here but for anyone wanting to really dive deep into this diverse terroir, I very highly recommend Peter Liem’s Champagne, one of my 5 essential books on Champagne.

(2:00) Panaiotis does note, however, that the northern side of the Montagne de Reims (which includes the Grand Cru villages of Mailly, Sillery, Verzy and Verzenay) produces wines with more fresh acidity that have great aging potential.

Chardonnay From the Heart of Pinot-country

By Map data (c) OpenStreetMap contributors, CC-BY-SA• derived via osm download geofabrik.de and osm2pgsql, OpenStreetMap contributors.• Data for landuse: OSM - derived wor CC BY 2.0,

The village of Sillery is located southeast of Reims and north of the Grand Crus of Mailly, Verzenay and Verzy.

(2:23) Even though the Montagne de Reims is known for Pinot noir, the eastern villages (mostly premier cru) are esteemed for the quality of their Chardonnay. Panaiotis describes how the gentle eastern exposure of these villages is similar to the Cote d’Or’s east-facing escarpment. Ruinart uses a lot of this fruit for their blanc de blancs Champagne.

(3:49) Sillery is the only Grand Cru of the Montagne de Reims that has more Chardonnay than Pinot noir.

(5:37) Kruth asks Panaiotis how much of Ruinart’s Chardonnay comes from the Montagne de Reims. It is around 30%.

(5:52) Instead of keeping the juice from different villages separate, Ruinart blends the wines regionally. The reason for this is logistics and the need to fill up tanks quickly. As I noted in the last Geek Notes on the process of Champagne, this is a significant divergence in the mindset of small growers versus big houses.

An Overview of Vintages

(8:26) Kruth asks about the recent vintages of Champagne. 2007 was a Chardonnay year while rain took a toll on Pinot noir and Meunier. In contrast, 2008 was more of a Pinot year. 2009 was a warmer year producing more rounder wines. While Panaiotis doesn’t elaborate, I’m curious if he was insinuating that he’s not expecting the 2009s to age as long as other vintages. But the trade-off could be more approach-ability when younger.

(9:36) 2010 is similar to 2007 in being a Chardonnay year. Panaiotis seems high on this year for Ruinart Champagnes. He compares it to 2002 regarding power but with more freshness and expects it to be a benchmark year. However, also like 2007, this was more of a difficult year for the Pinots.

Chardonnay Years vs Pinot Years

Chardonnay harvest in the village of Festigny (an Autre cru) in the Vallée de la Marne.

While it is a bit simplistic to think of years as Chardonnay years or Pinot years, it is a good starting point. Each of the major houses has a distinctive “house style” that tends to lean more on one grape variety or the other. Of course, they are going to try to make the best Champagne they can every year. But it is worthwhile to make a mental note of which years tend to favor a particular house style–especially if you are thinking about splurging for a prestige cuvee.

For instance, other Chardonnay-dominated houses like Ruinart include Perrier-Jouët, Taittinger, Laurent-Perrier and, of course, blanc de blancs specialists like Salon.

Pinot dominated houses include Lanson, Piper-Heidsieck, Mumm, Nicolas Feuillatte, Champagne Mailly, Veuve Clicquot and Moët & Chandon.

(10:11) 2011 was a tough vintage all around because of rain and botrytis infection. There will likely not be many vintage Champagnes produced. 2012 was a puzzling vintage for Panaiotis because the grapes came in so healthy yet the base wine didn’t live up to his exception to make great a prestige cuvee for Ruinart. He suspects that the year will be better for Pinot dominated producers.

The Wrath of the Drosophila suzukii

The spotted wing Drosophila suzukii wrecked a lot of havoc throughout Europe during the 2014 vintage.

(11:12) 2013 was an easy year with good wines produced. Meanwhile, 2014 had a lot of rot issues caused by an invasion of a Japanese fruit fly that devastated many vineyards (particularly the Pinots). This hit not only Champagne in 2014 but also Germany, Rhône and Burgundy.

However, the fly had issues “seeing” white grapes so the vintage wasn’t as bad for Chardonnay. Still, Panaiotis describes it mostly as a “non-vintage year”.

(12:12) 2015 was a good year but one characterized by drought and low-nitrogen levels in the must. For Ruinart, 2016 was a non-vintage year but Panaiotis notes that some producers like Villamart will be making very good 2016 vintage Champagnes.

(12:35) The 2017 vintage will be interesting because of how mature the grapes were harvested, even though they were picked relatively early. This is a vintage where the impact of global warming will be felt. The year is tilting towards a Chardonnay year (with the Pinots having some rot issues) but will be good for non-vintages.

The Importance of Primary Fermentation

Temperature control during primary fermentation is vitally important in maintaining freshness in Champagne. Here in one of the fermenting rooms of Moët & Chandon each tank is outfitted with a cooling jacket.

(14:10) The conversation switches to fermentation. There is a little overlap with the last podcast in the discussion of things like reductive winemaking.

(17:29) Kruth gives a great analogy of how the effects of the first fermentation get amplified in the secondary fermentation of Champagne. This is a really important point to understand because so often this fermentation gets overlooked because it isn’t the step that produces the “magic” of the bubbles. Yet, a Champagne is only as good as its base ingredient–the vin clair.

(18:13) The reasoning above is why Panaiotis is not a fan of using oak in the first fermentation at Ruinart. However, for other producers like Krug, the “amplification” of those flavors is a house style.

(19:24) One unique thing that Panaiotis mentions in his parting comment is that for the 2010 vintage, Ruinart switched to sealing the wine for the secondary fermentation with cork instead of the traditional crown cap. This is an exciting trend that is getting a lot of attention of late. The idea is that cork allows for better interaction with oxygen and the yeast but there seem to be other benefits as well–including more reductive flavors (!?) Certainly something I want to investigate more.

Interview With Rodolphe Péters of Pierre Péters

The chalky limestone of Champagne A fascinating produced at the same time as the White Cliff of Dover.

(20:50) As the interview switches to Peters, the focus shifts to the terroir of the Côte des Blancs. The origins of the region’s soils are similar to the Montagne de Reims–the ancient sea that birthed the Paris Basin as well as the White Cliffs of Dover.

However, the biggest difference between the two regions is the depth of the topsoil with the soil being much thinner in the Côte des Blancs. This is one of the reasons why Chardonnay is favored here since it can deal with shallow top soils easier than Pinot noir.

(22:59) Another comparison between the Côte des Blancs and the Cote d’Or with its north-south band of vineyards that face east. But here Peters points out the favor-ability of east-facing slopes–the gentle early morning heat of the sun instead of the harsher late afternoon heat that hits others exposures.

This is helpful in slowing down the maturation of Chardonnay which can risk losing elegance and flavor if it ripens too much, too quickly.

(23:54) Echoing again some of the sentiments of Frédéric Panaiotis in the first half, Peters calls out the specialness of Chardonnay from the eastern villages of the Montagne de Reims–particularly the Premier Cru villages of Trépail and Villers-Marmery.

The links to the villages above go to one of my favorite blogs on Champagnes. Each profile also includes a list of growers who produce Champagnes from these villages. These will be high on my list of Champagnes to seek out.

The Four Seasons of the Côte des Blancs

(24:21) Kruth asks for an overview of the different villages of the Côte des Blancs. Peters responds with a very poetic comparison of the personality of the main villages to the four seasons. Le Mesnil-sur-Oger is winter, producing tight Champagnes that can be austere in their youth. This is caused by, in Peters’ opinion, the soft and dry chalk that accentuates the wine’s sharp minerality.

The Grand Cru village of Oger is on flatter land and at a lower altitude than neighboring Le Mesnil-sur-Oger.

While Oger has the same soil profile as Le Mesnil, it is a little flatter and lower in altitude. This creates an amphitheater that warms up the micro-climate of the village, producing softer and rounder wines. Peters equates the style of wine from here to spring with an elegant and feminine character.

Avize is also lower altitude with the best sites located on flat terrain. It has a little deeper topsoil with some clay mixed with the chalk. This is unique compared to the other Côte des Blancs villages because it has a higher concentration of organic material in the soil. This produces a richer, juicer more citrus-style of Chardonnay that Peters equate to summer.

Vineyards in Cramant tend to have an “oilier” chalk that produces creamier style Champagnes.

Cramant is a little higher than Avize in altitude with an “oilier” style of chalk as opposed to the soft and dry chalk of Le Mesnil. This lends itself towards creamier and more approachable Champagnes. Along with the hazelnut and sweet baking spices that they tend to produce, this profile reminds Peters of autumn.

Viticulture and Climate Change

(29:45) Kruth asks about what differences in viticulture that are seen in the Côte des Blancs compared to other regions of Champagne. Peters notes that his personal approach is a little different than his neighbors. One of his priorities is to minimize compaction of the thin topsoil by limiting the amount of disturbance it sees.

For instance, he cultivates grasses between his vines but doesn’t plow it in. The one exception is in Avize, with its deeper topsoil, which can take some light plowing. However, he is also mindful of the character of a vintage with rainier years sometimes requiring a different approach.

Adapting to Change

While Chardonnay has adjusted to rising temperature, riper Pinot Meunier grapes can create problems with tighter clusters that are more prone to botrytis.

(31:45) Peters notes that Chardonnay growers in the Côte des Blancs have been relatively lucky with a string of good quality and easy vintages. Meanwhile, Pinot producers (particularly Meunier) have had to be on their toes a lot more with the weather change.

One of the challenges for Pinot Meunier that Peters highlights is that the warmer weather is producing bigger, riper berries. While this might seem beneficial on the surface, the stems are not getting any bigger. Therefore, the Pinot Meunier clusters are getting tighter and more compact which increases the risk of botrytis rot, especially in rainy vintages.

(33:09) Chalk is a winemaker’s best friend because of how well it regulates the climate–especially excessive water during rainier vintages. But it also retains water well during drought years. Likewise, the soil is able to deal with hot vintages by absorbing heat and then slowly releasing it later in the night so that the vine is not overwhelmed.

(33:40) Peters notes that over the years, he has seen the major houses gradually increasing the amount of Chardonnay they use due to the grape’s ability to better weather climate change.

A Contrast of Vintages

(34:08) Kruth asks for Peters thoughts on particular vintages. He highlights a few that he thinks are interesting–2013 and 2017.

The 2013 vintage was a long growing season with 104 days of maturation. This allowed the grapes to get perfectly ripe without being excessively mature. In contrast, 2017 was very hot which caused a spike in sugars. Peters noted that growers had to start picking their grapes after 87 days to avoid high alcohol.

However, Peters feels that many of these early harvesters didn’t taste their grapes with the resulting wines still having unripe flavors. He waited till 91 days to get some more maturity. He feels that 2017 is the first vintage that the Champenois really had to face the reality of climate change.

Grand Marque vs Grower

Paul Bara, one of the first grower producers to gain traction in the US.

(37:35) The conversation moves to the general impression of grower-producers, especially in the sommelier community. Kruth wonders if it has now become a marketing wedge like Red States vs Blue States, Grand Marque vs. Grower, etc. He particularly calls out sommeliers who only feature grower Champagnes on their wine lists.

Peters response gives some interesting food for thought and is well worth a listen. He does see benefits of the big houses but notes they have some issues. While grower Champagne answer some of those issues, Peters is not a fan of the idea that merely because something is a grower that it must be good.

(40:45) A really interesting discussion follows Kruth describing the “trick of oxidation” that he feels that some growers utilized to make up for the lack of aging and use of reserve wines. He contrasts this with the long, slow reductive aging of many great Champagnes. This is particularly fascinating in the context of Chardonnay-dominant producers because of how much affinity Chardonnay has for reductive winemaking and how awry it can get without a careful hand if treated oxidatively.

A very thought-provoking conversation to end the podcast on.

Geek Notes — The Process of Champagne GuildSomm Podcast

Amber LeBeau in Champagne, Geek Notes

Published on December 8, 2018

Back in 2013, GuildSomm did a fantastic podcast with Frédéric Panaiotis (39:33) of the Champagne house Ruinart about how Champagne is made. They followed it up with another interview with Panaiotis this year on Champagne (44:54) that also featured Rodolphe Péters of Pierre Péters.

Guildsomm podcast screen

Both shows are chock-full of awesome behind-the-scenes insights about Champagne that are well worth listening to. I’m going to break down the 2013 episode here first and then devote another Geek Notes to the second interview.

But after doing multiple Geek Note reviews of various podcasts (like Grape Radio’s interview with Hubert de Boüard of Ch. Angélus, UK Wine Show episode with Ian D’Agata about Italian wine grapes, Wine For Normal People’s episode on Tuscan wine regions and I’ll Drink To That! interview with Greg Harrington on Washington wine), I realize that I should take a moment to explain the objective of these posts.

Highlighting Learning Tools That I Use

As I mentioned in my post SpitBucket on Social Media, the purpose of my Geek Notes features are to highlight valuable resources for wine students pursuing various certifications.

Wine podcasts are a big focus for me because I think they’re often extremely underutilized. It’s easy for wine students to bury their heads in books and create flash cards. But we shouldn’t discount that nearly a third of individuals are auditory learners. Furthermore, for the 65% who are visual learners, exposing ourselves to audio avenues helps reinforce the material that we’re learning.

However, most people are actually a mix of multiple learning styles so the best approach is to also incorporate kinesthetic (hands-on) learning as well.

This is essentially what I’m doing for myself with these Geek Note reviews of podcasts. I’m primarily a visual learner so I’m always diving into one wine book or another. But when I’m going deep on a topic, I supplement that book learning by listening to related podcasts.

When I come across a podcast with useful information, I go back to listen to it a second time. This time, I take notes. It’s like recording your class lectures back in college. You spend class time actually listening to the instructor and absorbing the material first without distracting scribbling and note taking. But then you solidify the material in your mind by going back to the recorded lecture for notes.

A little bit of a review element.

While I’ll include timestamps, I don’t really intend for these posts to be transcriptions. If I’m doing a review of a podcast, it’s because I feel that it is sincerely worth listening to. There will often be contextual tidbits and stories featured in these episodes that I won’t mention or fully address. You can get more out of these Geek Notes by checking out the podcasts for yourself after reading these posts.

For newer podcasts like my recent reviews of the Decanted podcast and the Weekly Wine Show, I’ll spend more time giving background about the podcast and why I think they’re worth subscribing to.

In many ways, great wine podcasts are like stellar reference books like The Oxford Companion to Wine, The World Atlas of Wine and The Wine Bible. They provide you with an entire library of wine knowledge that you can digest one entry at a time.

In the next Geek Notes, I’ll give a little background about GuildSomm but, right now, let’s dive right into their podcast interview with Frédéric Panaiotis on making Champagne.

Fun Things I Learned From This Podcast

(0:52) Prior to joining Ruinart, Frédéric Panaiotis also previously worked for Veuve Clicquot, the CIVC as well as the California sparkling wine producer Scharffenberger in the Anderson Valley of Mendocino.

(3:16) Historically, the CIVC used to set one general ban des vendanges for the region. This is the first day that grapes can be legally harvested. Now there are multiple ban des vendanges based not only on the village but also on the individual grape variety. And apparently rootstock in some cases too.

For instance, in the Grand Cru village of Mailly for the 2018 vintage they were allowed to start picking Pinot Meunier on August 25th. However, for Chardonnay and Pinot noir (which the village is most noted for), growers had to wait till August 27th.

I’m curious about the ban des vendanges for other grape varieties–Fromenteau/Pinot gris, Pinot blanc, Petite Meslier and Petite Arbanne. I couldn’t find the answer online but I’ll keep looking.

BTW, August start dates were historically unusual in Champagne but are now becoming much more commonplace. This recent 2018 vintage was the fifth year since 2003 to begin in August.

(5:45) You can get a special allowance from the CIVC to harvest earlier. According to Panaiotis, this may be needed if you are harvesting from a really young vineyard of 3 years or were hit by spring frost which drastically reduced yields. Apparently with less clusters to focus on, the vine will accelerate ripening.

That strikes me a bit curious because wouldn’t the same logic apply to old vines which also produce lower yields. Wouldn’t they also ripen faster? Need to research this more.

Harvest Brix and Ripeness

Chardonnay grapes harvested in the village of Vertus.

(6:21) Panaiotis notes that the Champenois usually aim to harvest grapes at around 10% potential alcohol which is about 18-19° Brix. Compare this to typical still wine production where producers want to harvest Chardonnay more at 20-23° Brix and Pinot noir around 25-27°. But, keep in mind, the secondary fermentation of Champagne (where sugar and yeast are added) adds more alcohol to the finish wine. Most Champagnes finish with an ABV in the 12-12.5% range.

(8:00) A big distinction that GuildSomm’s Geoff Kruth and Panaiotis note about Champagne is that even at these low brix levels, the grapes are still ripe. Panaiotis gives the example of the 1988 vintage which was picked at many estates at around 9.2% potential alcohol (17.5° Brix) in a year that was a late harvest for Champagne. This vintage is still highly regarded for its richness and longevity. Yet harvesting something at so low of a brix level in most any other wine region would produce wines abundant in green, unripe flavors.

This is a quandary that sparkling wine producers from warmer climates like California and Spain have to deal with because acidity is also at play. Not only is it hard to get desired ripeness with such low brix but you need to harvest your grapes with ample acidity. While improvements in viticulture and planting in cooler vineyard sites have helped, historically producers from warm regions have needed to harvest the grapes at lower ripeness levels in order to have enough acid to make their sparkling wines.

The Controversial 1996 Vintage

(8:55) In contrast to 1988, Panaiotis describes the 1996 as an “unripe” year even though the grapes were harvested at 10.5% potential alcohol (20° Brix). This is intriguing because there is a lot of controversy going on now about the 1996 vintage which Jancis Robinson aptly explains in one of her Financial Times articles.

When the 1996 Champagnes were first released, many Champagne lovers were enthralled. That year was pegged as one of the top vintages of the 20th century. I will admit that, even though I’ve been extremely underwhelmed by their recent offerings, the 1996 Dom Perignon was one of the greatest wines that I’ve tried in my lifetime. But I had that wine soon after release and it seems that as the 1996s across the board have aged, more and more people are re-evaluating how good that vintage really was.

Challenges of Big Houses

By law, Champagne grapes have to be harvested whole cluster and by hand.

(9:20) Here Panaiotis talks about the challenges that big houses have versus small growers with harvest–particularly with red grapes like Pinot noir. Because the goal in Champagne most often with Pinot is to make a white wine, time is of the essence as soon as you remove the cluster from the vine. You don’t want any “cold soak” color extraction taking place in the pick bin. With Chardonnay, avoiding oxidation of the juice is also a concern for many houses.

But what do you do when you are a large house whose winery is maybe several miles away from the many vineyards you source from? Well worth listening to see how Ruinart responds to this challenge.

(10:30) Machine harvesting is forbidden in Champagne. Part of the reason is because machine harvesters can only harvest individual berries. They do this by using beater bars to separate the berries from clusters on the vine. If you’re curious, this short (2:18) ad video for a mechanical harvester gives a great inside view into how these harvesters work. Panaiotis thinks that even if someone developed a machine that could somehow harvest grapes whole cluster that it would still probably be outlawed.

Pressing Details

A modern bladder press.

(11:54) Panaiotis estimates that among the various presses used in Champagne, about half are modern bladder presses with the rest being the traditional Coquard basket press. Piper-Heidsieck has a quick 1 minute video of the Coquard press in action with Pinot noir. Note how the juice, even with the whole clusters, is already being tinted with color. And, yes, leaves and other MOG often gets thrown into these large batches.

(12:15) In Panaiotis’ opinion, 70-80% of the resulting quality of the wine comes from the pressing process. This is an interesting departure from the opinion that a lot of the quality of Champagne comes from the blending and time aging on the lees. From here he goes into a great description of the different cuts (cuvée and taille) that are separated in the pressing process. To explain this he uses a comparison that you can do in a vineyard while sampling a single grape berry.

(14:47) At Ruinart, Panaiotis likes using the taille for their non-vintage Champagnes. Here these cuts add roundness and fruitiness but there is a trade-off in decreased aging potential. In contrast, Ruinart’s vintage wines are almost all cuvée juice since the lower phenolics in this first cut is less prone to oxidation.

This makes me curious about the pressing philosophy of Champagne houses that value more oxidative styles like Krug.

Fermenting as separate lots or as regional blends

(16:10) When Kruth asks how Champagne producers keep the juice from different villages and vineyards separate, Panaiotis explains some of the logistical problems of that. While it is ideal to keep different villages separate, it may take you several days to receive enough lots from those villages to eventually fill an entire tank. That reality favors blending more regionally–like all the Côte des Blancs villages together.

I suspect this is more of an issue for large Champagne houses who presumably have very large tanks with several thousand liter capacities that need to be filled. Additionally, with so many contract growers there is probably a fair amount of variability in what kind of yield you can expect each year from different villages/vineyards, etc. In contrast, smaller growers who have been tending their own vines for generations probably know more precisely what they are getting and accordingly have smaller tanks that are easier to fill up and keep separate.

Another key point specific to Ruinart is that their house’s style is very reductive. If the tanks aren’t filled quickly, there is a risk of the juice oxidizing before fermentation takes off.

Style Differences

(17:14) At Ruinart, they aim for very clean and neutral flavors in their base wines. Along with wanting to avoid oxidation, they use sulfur on the juice to also knock back wild yeast so that they can inoculate with cultured yeast. Kruth notes that the impact of wild or native ferment produces flavors that get amplified during the secondary fermentation, something Panaiotis wants to avoid at Ruinart.

Lanson is another house that has historically avoided malolactic fermentation but has recently been experimenting with MLF on a few lots.

(19:30) Panaiotis likes the round mouthfeel that comes from initiating malolactic fermentation in the Champagnes of Ruinart. This is a stylistic decision relating to different Champagne house styles. Some producers, most notably Gosset, historically avoid malolactic fermentation so they can maintain natural acidity and aging potential. But the trade-off is mouthfeel and softness with even Gosset experimenting with having some batches going through MLF.

(20:24) A very interesting discussion on the different philosophy of using reserve wines in the blends of non-vintage Champagnes. Panaiotis describes the impact of using older versus young reserve wines on the resulting style of Champagne. He notes that Ruinart’s precise style favors using younger reserve wines while houses with a more mature style like Charles Heidsieck prefer using older reserve wines of up to 10 years of age.

Secondary Fermentation Issues

(24:18) Probably my biggest surprise was learning about the issues of calcium tartrates in Champagne. If wineries don’t remove these unstable tartrates via cold stabilization, there will be excessive foaming during disgorgement. Worst, this foaming could happen when the wine is opened by consumers–creating a mess. I always thought it was more about aesthetics with consumers mistaking the tartrate crystals for shards of glass.

(25:47) Another completely new thing I learned was that the actual length of time of the secondary fermentation is about 6 to 8 weeks. I always thought it was much quicker like primary fermentation which usually takes several days to a couple weeks. Panaiotis does note that as soon as 3 days after bottling you can start to see the dead lees collecting in the bottle.

(26:52) Panaiotis reveals that recent studies of the Champagne process is showing that oxygen intake through the crown cap or cork is just as impactful on the resulting flavor of the wine as autolysis is.

Oxidative vs Reductive

Bollinger Champagnes have been traditionally associated with an oxidative style of winemaking.

(28:22) Panaiotis goes into an in-depth discussion of oxidative versus reductive winemaking. He details many of the decisions that he has to make throughout the process to promote Ruinart’s reductive style including the unique technique of jetting. Here winemakers add a little bit of water or nitrogen (and sometimes sulfur) to the wine before corking to promote foaming that pushes out the oxygen. This short video (0:52) is in French but shows the process well.

(31:10) Kruth asks for example of major houses who follow the different styles. Panaiotis notes that along with Ruinart, Laurent Perrier, Mumm, Pierre Gimonnet, Pierre Moncuit and Pierre Peters are on the reductive side while Bollinger, Krug, Jacquesson and Jacques Selosse are on the oxidative side. He also notes that Pinot noir favors the more oxidative style. Interestingly, most of the houses he mentions that favor a reductive style tend to be Chardonnay dominant.

(37:40) Panaiotis notes that the CIVC legally limits how many grapes negociants can buy each year. While he didn’t seem completely certain, he estimates that the limit is a maximum of 30% above the equivalent of your previous year’s sales. I’m guessing the CIVC sets these rules to prevent stockpiling? But there is no law on the amount of land you can own. Another tidbit from Panaiotis, growers can buy up 5% of their grapes and still be considered a grower producer.
