The process that creates the bubbles in sparkling wine. As the wine is bottled, a small amount of yeast and sugar is added before the bottle is sealed with a sturdy crown cap. The yeasts quickly start fermenting the sugars, producing alcohol and carbon dioxide. Since the gas cannot escape, it dissolves into the wine.
In bottle-fermented sparkling wines, a small amount of wine (usually mixed with sugar) that is added back to the bottle once the yeast sediment that collects in the neck of the bottle is disgorged. Also known as liqueur d'expedition.
Malolactic Fermentation (ML):
A bacterial conversion occurring in most wines, this natural process converts sharper malic acid (found in green apples) into softer lactic acid (found in milk). Total acidity is reduced; the wines become softer, rounder and more complex. In addition, malolactic fermentation stabilizes wines by preventing an undesirable fermentation in the bottle. Often called the secondary fermentation. Frequently associated with big, rich, buttery Chardonnay, malolactic fermentation is prevented when fresher, crisper styles are desired.
Indicates that the lees have been removed from a sparkling wine just prior to release. After sparkling wine has undergone the second fermentation in the bottle, the wine can remain on the lees for many years to develop additional complexity and richness.
The labor-intensive process whereby wine undergoes a secondary fermentation inside the bottle, creating bubbles. The process begins with the addition of a liqueur de tirage (a wine solution of sugar and yeast) to a bottle of still base wine, triggering a secondary fermentation inside the bottle which produces both carbon dioxide and spent yeast cells, or lees, which are collected in the neck of the bottle during the riddling process. The lees are then disgorged from the bottle, and replaced with a solution of wine and sugar, giving the sparkling wine its sweetness. All Champagne and most high-quality sparkling wine is made by this process. Also known as méthode Champenoise, méthode classique and metodo classico.
An inexpensive but risky and difficult-to-control method of producing sparkling wine, and almost certainly the oldest, in which the primary fermentation is stopped before completing, and a secondary fermentation occurs in the bottle, ending when the yeast cells deplete the supply of residual sugar. There is no dosage, or sugar addition, to kick-start the secondary fermentation, and the wine is not disgorged to remove any sediment or lees remaining afterward.

Liqueur de Tirage:
A solution of wine, sugar and yeast added to a bottle of still base wine to begin the traditional method of making Champagne, or méthode traditionnelle. The addition of the liqueur de tirage triggers the secondary fermentation which gives sparkling wine its bubbles.
Sparkling wine production method for traditional Prosecco, in which the spent yeast cells, or lees, left over from the secondary fermentation are not disgorged.
