Harvest may be the most visible moment in the wine year, but for a Bourgogne winemaker it is far from the end of the process. Once fermentation is complete, the wine enters a quieter and often lengthy phase: élevage. Only when the winemaker believes the wine has developed sufficiently is it prepared for bottling (mise en bouteille). There is no single timetable. Twelve months of élevage is entirely normal in Bourgogne, while many wines remain in the cellar for considerably longer. Depending on the appellation, vintage and philosophy of the producer, élevage may last anywhere from several months to around two years.
What happens during élevage?
The French word élevage is difficult to translate precisely. “Ageing” comes close, but does not quite capture its meaning. Literally, it suggests raising or bringing something up. The wine is not simply left to wait: it is guided from newly fermented wine towards its finished form. During this period, wine may rest in oak barrels, stainless-steel tanks, concrete vessels or a combination of these. The choice has a considerable influence on its development. A traditional Bourgogne pièce holds 228 litres, but larger barrels are increasingly encountered as well. Time allows aromas and texture to develop, while the wine gradually becomes more integrated. Wines kept on their lees can gain additional texture and complexity. Barrels also allow a small amount of oxygen to interact with the wine. Depending on the producer, the wine may be topped up, racked, stirred or simply left as undisturbed as possible. Longer élevage does not automatically mean better wine. The aim is to give a particular wine the time and environment it needs.
Different traditions across Bourgogne
There are broad regional tendencies, although individual domaines frequently depart from them.
In Chablis, stainless steel remains particularly important because many producers want to preserve freshness, acidity and the direct expression of Chardonnay and its limestone-rich soils. Oak is nevertheless far from absent. Some domaines use older barrels or a combination of barrel and tank, particularly for Premier Cru and Grand Cru wines. Longer élevage is not unusual either: some Chablis producers bottle their more serious wines 18 months or more after harvest.
In the Côte de Nuits, where Pinot Noir dominates, élevage in oak barrels is deeply established. Village, Premier Cru and Grand Cru wines commonly spend well over a year in barrel. During this period, tannins settle and integrate, the texture develops and the different components of the wine begin to come together. New oak may be used, but its proportion varies enormously between domaines and cuvées.
The Côte de Beaune has both important red-wine traditions and some of the world’s most celebrated Chardonnay vineyards. In villages such as Meursault, Puligny-Montrachet, Chassagne-Montrachet and Saint-Aubin, white wines are frequently fermented and raised in barrel. Élevage of around 12 to 18 months is common among quality-conscious producers, although both shorter and substantially longer approaches exist. Red wines from appellations such as Volnay, Pommard and Savigny-lès-Beaune often follow a broadly similar timetable to those of the Côte de Nuits.
In the Côte Chalonnaise and Mâconnais, practices are particularly varied. Stainless steel may be preferred for fresher, earlier-drinking wines, while more ambitious Chardonnay and Pinot Noir cuvées can receive extended élevage in barrel. Appellation level alone therefore tells only part of the story: the producer’s philosophy is equally important.
Deciding when to bottle
Bottling is a decision rather than simply a date on the calendar. Throughout élevage, the winemaker tastes the wines and follows their development. Different barrels or parcels destined for the same cuvée may eventually be assembled before bottling. The wine may also undergo fining or filtration. Fining helps remove suspended particles, while filtration can improve clarity and microbiological stability. Neither is obligatory, and some producers deliberately bottle with little or no filtration in an effort to minimise intervention.
Once the wine is bottled, its development does not stop. In fact, bottling begins another phase. A young wine can temporarily become less expressive after bottling — sometimes referred to as bottle shock — before settling and continuing its evolution in glass. This explains why the vintage on a Bourgogne label does not necessarily tell you when the wine reached the market. A wine harvested in September may still be resting in barrel or tank when the following harvest takes place. Some producers will already be selling that vintage the next spring; others may not bottle their most important wines until the following year, or even later.
In Bourgogne, patience in the cellar is part of winemaking. Bottling is not simply the final operation after fermentation. It is the moment at which the winemaker decides that élevage has done its work — and that the wine is ready to continue its life in bottle.
