Sur lie is a French term meaning “on the lees.” It describes wine that is matured in contact with the sediment of dead yeast cells and other fine particles left after fermentation, rather than being immediately racked off. Lees contact can contribute texture, complexity and, in some wines, aromas associated with bread, yeast, nuts and pastry.
After fermentation, the wine remains in contact with selected fine lees in a tank, barrel or other vessel. The producer manages the lees according to the desired style and the condition of the wine. Some wines are left undisturbed, while others undergo periodic stirring known as bâtonnage. Gross lees and unwanted deposits are generally separated from the wine.
Lees contact can contribute a fuller mouthfeel, creamy texture and greater aromatic complexity. In traditional-method sparkling wine, extended lees ageing after the second fermentation can develop brioche and biscuit notes through autolysis. In still wines, lees ageing may add texture and savoury complexity without necessarily creating pronounced yeast aromas.
Muscadet Sèvre et Maine sur lie is a well-known example. The wine is matured on its lees under the appellation’s rules and often shows freshness, subtle texture and a slight spritz. Chardonnay and other white wines may also be aged sur lie in barrel or tank.
Example: serve Muscadet Sèvre et Maine sur lie with oysters, shellfish or grilled fish; its acidity and texture work well with seafood.
Sur lie describes the wine’s contact with lees. Bâtonnage is the practice of stirring the lees back into suspension. A wine may be sur lie without being stirred.
Chef’s note: lees ageing is a winemaking choice, not a guarantee of creaminess or quality. The result depends on lees condition, duration, vessel and handling.
