With 2020 coming to a close, I am posting the top sparkling wines, but to be clear, I drink sparkling wine all year round! We have been blessed recently with Yarden selling their Gilgal Sparkling wine for under 20 dollars a bottle! Honestly, there is no better deal out there and that is why they were the wines of the year last year! Yarden continues to impress with their 2014 entries and they are the sparkling wine producers to beat, for anyone entering this market.

How is Sparkling wine made?

There are many options – but the vast majority of sparkling wines fall into three categories:

• Le Méthode Champenoise (Méthode Traditionnelle)
• Methode Ancestrale
• The Charmat Method

Le Méthode Champenoise (Méthode Traditionnelle)

So, what is Champagne and how do we get all those cool bubbles? Well, it all starts with a grape of some sort, in most cases, Chardonnay, but we will get back to the other varietals further down. For now, like all wine on planet earth, Champagne starts with a grape. It is picked (often early to lower alcohol and increase acidity), then crushed, pressed, and allowed/encouraged to go through primary fermentation, exactly like all white wines on planet earth. At this point, most houses ferment the base wine in metal tanks or barrels. Some still use wood, but they are the minority.

Of course, like much of France (Bordeaux, Burgundy, Champagne), especially in Champagne, the wine can be chaptalized after racking, until an 11% ABV. Now before the heat waves that have covered much of this earth (call it what you wish), Bordeaux and Champagne prayed to hit their desired mark of ABV, and therefore they used to add sugar to bring up the ripeness on their fruit. Nowadays, Champagne is picking earlier and earlier, and Chaptalization is not a common thing anymore, as mother nature is taking care of the fruit’s ripeness all on her own!

Once the wine has been fermented the next question arises, should they let the base wine go through a wine’s second natural fermentation called Malolactic Fermentation? Most allow the fermentation to take place and require it, a fact that is easy nowadays with controlled winery environments, though some do not like it at all. Finally, the barrels/tanks are blended or in the rare case, kept aside as a Vintage Champagne, meaning the base wine used in it, is sourced from one vintage and not a blend of a few vintages.

So, at this point what we have is base wine, and while it may be an OK wine, it is far from what the final product will be like. Most base wines are nice enough, but it would be like licking on a lemon, these wines are highly acidic, and not normally well balanced at that point.

The next step is to bottle the wine, with yeast and basic rock sugar, which causes a second fermentation. The actual amount of the two added ingredients is a house secret. The wines are closed with a simple beer bottle cap. You will notice that ALL wines made in this manner have a lip around the top of the bottle, where the cap is attached to. Again, if the year is exceptional then the wine becomes vintage champagne and is aged for at least three years. If the vintage is normal then the bottle’s content is a blend of a few vintages and is aged for at least one and a half years.

All the while during this second fermentation process, the wine is aged and the wine becomes more complex from the yeast. The yeast breaks down as it eats the rock sugar, adding the effervescence, and while the yeast breaks down, it adds a lovely mouthfeel and rich complexity. This process is known as autolysis, releasing molecules that are slowly transformed as they interact with those in the wine.

The process is a dual transformational process. First, the yeasts are broken down, but if that occurred in a 100% hermetically sealed environment, we would have SERIOUS issues, like HS (Hydrogen Sulfide) and mercaptan (think nasty rotten eggs). Oxygen is a two-edged sword, with too much a wine oxidizes, and with too little, you get HS and nasty foul egg smell. So, the cap that covers the Champagne bottles as they rest for 18 months to 3 years in these cool racks, actually allow for a certain amount of oxygen to flow through, the caps are not hermetic seals. The special stoppers, AKA caps, allow the wine to mature on the lees, with a very slow feed of oxygen coming through, thereby allowing the wine to mature at a rate that is best for it. You can mature them quicker, with a different cap, but you would lose the value of a wine sitting long on the lees.

According to Wikipedia, the effects of autolysis on wine contribute to a creamy mouthfeel that may make a wine seem to have a fuller body. The release of enzymes inhibits oxidation which improves some of the aging potentials of the wine. The mannoproteins improve the overall stability of the proteins in the wine by reducing the number of tartrates that are precipitated out. They may also bind with the tannins in the wine to reduce the perception of bitterness or astringency in the wine. The increased production of amino acids leads to the development of several flavors associated with premium Champagne including aromas of biscuits or bread dough, nuttiness, and acacia. As the wine ages further, more complex notes may develop from the effects of autolysis.

Finally, it is at this stage, after the bottles have matured their proper time, based upon their label (blend or Vintage), we get to the final stage of Champagne, remuage (or “riddling” in English) and Dosage. To get rid of the lees (the dead yeast cells and other particulates), the bottles are hand or machine manipulated to convince the lees to move towards the cap. Then the neck of the bottle is frozen, and the cap is removed, the lees come flying out in a frozen format, and then the bottle is recapped with the famous champagne cork, but not before it is dosed with more sugar. This very last step is the reason for this post, but let’s leave that till further down in the post, for now, let’s talk varietals and color/style.

Color/style and Varietals

So, we have covered the how part of Champagne (well almost more on Dosage below), and now we need to talk color and grapes. The base grapes for Champagne are Pinot Meunier, and Pinot Noir, and Chardonnay. There are very few houses that also use Arbane, Petit Meslier, Pinot blanc, Pinot Gris. Champagne, like the rest of France’s wine industry, is controlled by the AOC (appellation d’origine contrôlée).

So, for Blanc de Blancs Chardonnay, which is white from white, Chardonnay is the only grape allowed. Meaning, that the juice from Chardonnay is 100% of a BdB Champagne, or in rare occasions from Pinot blanc (such as La Bolorée from Cedric Bouchard).

For Blanc de Noirs, the Champagne is made from either Pinot Noir or Pinot Meunier, or a blend of the two. Finally, for Rose Champagne, it can be a blend of the three grapes.

Late Disgorgement

This has been all the rave recently, LD or Late Disgorgement. All this means is that the house or winery (outside of Champagne) kept the bottles capped for a longer time. So the 2007 Yarden Blanc de Blancs was sold in 2014 or so. It is a lovely wine and recently Yarden released a 2007 LD Yarden  Blanc de Blancs. It is the same wine, just held longer in capped format (another 4 years or so), and then recently they disgorged the wine, more on that below, and put in the dosage and the Champagne style cork and released it now. Essentially, for all intent and purpose, Yarden aged the Sparkling wine 4 more years and released it later on. The interesting thing will be to taste the two wines (the LD and normal 2007 Yarden BdB and see how 4 extra years of lying on lees helped/hindered/or did nothing). I will be doing that soon enough.
