What is a common purpose of bottle aging on lees for sparkling wines?

• A. To reduce acidity
• B. To develop autolytic flavors and creamy texture
• C. To increase carbonation
• D. To sterilize the wine

Answer: (B)

A common purpose of bottle aging on lees for sparkling wines is to develop autolytic flavors and a creamy texture. When the wine sits on the dead yeast cells after secondary fermentation, those cells break down and release compounds like amino acids, peptides, and mannoproteins. This autolysis creates biscuit, bread, and brioche notes and also enhances the mouthfeel, giving a smoother, creamier, more velvety texture and a finer mousse. It’s not about lowering acidity, increasing carbonation, or sterilizing the wine—the aging on lees primarily builds complexity and creaminess through the yeast remnants.
