Base wine is the still wine used as the starting point for producing sparkling wine. In traditional-method production it is usually made with relatively high acidity, moderate alcohol and a clean flavour profile so it can develop through the second fermentation and lees ageing. The French term used for base wines in Champagne is vin clair.
Base wines are generally more acidic and less rounded than the finished sparkling wine. They may have lower alcohol than the final product because the second fermentation adds a small amount of alcohol. The desired base-wine style depends on the sparkling-wine region, grape variety and producer.
Producers may blend wines from different grape varieties, vineyard sites, villages or vintages to create the intended style. In Champagne, Chardonnay contributes acidity and finesse, Pinot Noir adds body and structure, and Meunier can contribute fruit and approachability. Reserve wines may be added to non-vintage blends to maintain consistency.
Once the base wine is blended, the liqueur de tirage is added and the wine is bottled for the second fermentation in the traditional method. In the Charmat method, the base wine undergoes its second fermentation in a sealed pressure tank instead.
Example: Champagne base wines from Chardonnay, Pinot Noir and Meunier are blended before tirage and the second fermentation in bottle.
Chef’s note: base wine is a technical production term. It is not usually the finished sparkling wine served to guests.
