Which statement about post-fermentation maceration is true?

• A. It serves to further extract and polymerize tannin
• B. It reduces tannin polymerization
• C. It eliminates color
• D. It stops fermentation

Answer: (A)

Post-fermentation maceration involves continuing contact between the wine and grape skins after alcoholic fermentation, so more tannins and color compounds can diffuse into the wine. This step can drive further extraction of tannins and pigments and promote polymerization of tannins—where tannin molecules join to form larger, more complex polymers. Those polymerized tannins contribute to a softer mouthfeel and greater aging stability, and they can help stabilize color by forming pigment–tannin polymers. Because fermentation has already finished, this process does not stop fermentation, it does not eliminate color, and it does not reduce tannin polymerization. The statement that it serves to further extract and polymerize tannin is the true description.
