There's a moment I keep experiencing with certain bottles: you nose the glass and immediately sense that a lot of time was involved here. Not the quick, fruity freshness of a young Champagne, but something deeper, calmer. Time is the quietest ingredient in Champagne, and it works on three quite different levels.
These three levels often get lumped together, but they're fundamentally different: the age of the vines, the age of the vintage, and the length of time on the lees. A wine can come from ancient vines and still be drunk young. Another can come from young vines and spend an eternity on the lees. Once you separate these three, it becomes much easier to understand why a Champagne tastes the way it does.
1. Old Vines: Vieilles Vignes
"Vieilles Vignes" appears on some labels, and there's no legal definition for it. In practice, it refers to vines that are clearly above average age, often 40 years and more. Some winemakers have parcels with vines that are 60, 80, or even over 100 years old.
Why this matters: a young vine grows quickly and bears a lot of fruit. An old vine has deep roots that reach far into the subsoil, yields less, and concentrates that yield into fewer grapes. The result is berries with more depth, more mineral expression of the soil, and less upfront fruit. Old vines are also more resistant to drought and temperature swings, because they draw their water from deep underground.
An example from my own cellar: the Le Mont de Reuil by Robert-Allait comes 100 percent from Meunier vines that were planted in 1923, meaning they're over 100 years old. You can taste that concentration: the wine has a density and a calmness that a young vineyard simply cannot deliver.
Another such case is the Instinct Meunier by Jeaunaux-Robin from the Petit-Morin valley: 61-year-old vines, aged in oak barrels, with just around 1,700 bottles produced. Old vines almost always mean small quantities too, the two go hand in hand.
2. Great Vintages: Millésime and Age
The second level is the age of the finished wine. Most Champagnes are blends of multiple years (non vintage). A Millésime, by contrast, comes from a single vintage, and a house only declares one when the year was particularly good. More on this in my post about Millésime.
Vintage Champagnes are made to age. What happens during that process is fascinating: the sharp citrus and apple fruit of youth gradually turns, over the years, into notes of brioche, roasted nuts, honey, sometimes dried fruit, and delicate spice. The mousse becomes gentler, the texture creamier, and the whole wine feels rounder and deeper. Wine nerds call this tertiary aromatics.
The Comtes de Champagne by Taittinger, vintage 2014 is one such case: a single-varietal Chardonnay prestige Cuvée with many years of age, in which you can taste exactly this transformation from fresh to layered. Prestige Cuvées are often the most mature wines a house produces. I've written about how they differ from standard Cuvées in my post on Prestige Cuvées.
3. Long Lees Aging: sur lattes
The third level is the most hidden one, because it happens after bottling, down in the dark cellar. After the second fermentation, the Champagne rests on its lees, "sur lattes" or "sur lie." The law requires a minimum of 15 months, and three years for vintage Champagne. Ambitious winemakers go far beyond that.
During this time, the dead yeast slowly breaks down, a process called Autolysis. This is exactly where the typical notes of fresh bread, brioche, and pastry come from, and it's exactly what gives a Champagne its creamy texture and length. More on this in my post on lees aging.
Just how far this can go is shown by the Cléo by Esterlin: a Blanc de Blancs with 128 months sur lattes, nearly eleven years on the lees. Or the 198 Millésime by Perseval-Farge: vintage 2006, tirage 2008, only disgorged in 2023, adding up to 15 years of lees aging, with zero Dosage and only around 1,000 bottles produced. Wines like these need to be drunk slowly, they grow bigger in the glass from minute to minute.
Why the Three Come Together
In practice, these three levels often overlap, and that's no coincidence. A winemaker who goes to the trouble of tending old vines rarely reduces that wine to a quick blend. Instead, they turn it into a vintage Champagne and let it age on the lees for a long time. That's how the three forms of time end up bundled into a single bottle.
This also explains why such wines are rare and only found in small quantities. Old vines yield little, good vintages don't come every year, and long lees aging ties up capital in the cellar for years. Time costs money, in the vineyard just as much as in the cellar.
If You Have Such a Bottle in Your Glass
Three things help aged Champagnes show their depth:
- Don't serve it too cold. A young, fresh Champagne can be served chilled. An aged vintage needs a bit more warmth for the tertiary aromas to unfold, closer to 10 to 12 degrees Celsius than 6.
- The right glass. No flute. A white wine glass or a tulip gives the complex aromas room to develop. If you drink a wine that's spent 15 years aging out of a narrow flute, you're giving away almost everything it waited so long for. (#saynotoflutes)
- Give it time. Wines like these open up in the glass. The first sip is often the most reserved. Wait a few minutes, then a few more.
Time is the ingredient you can't buy and can't speed up. That's exactly what makes these bottles so special: they're the result of patience, in the vineyard, in the cellar, and finally, in the drinking too.
