What is chaptalization?

• A. Addition of water to the must to lower sugar
• B. Addition of acid to adjust flavor
• C. Addition of sugar to the must to increase alcohol in final product
• D. Fermentation at high temperature

Answer: (C)

Chaptalization is the practice of adding sugar to the grape must before or at the start of fermentation to raise the wine’s potential alcohol. It’s used when grapes are underripe or grown in cool climates and don’t accumulate enough natural sugars for the desired alcohol level. The added sugar gives the yeast more fermentable substrate, so more ethanol can be produced as fermentation proceeds. It’s not about adding water to dilute sugar, which would lower alcohol potential, nor about adding acid to adjust flavor, which changes acidity rather than sugar. It also isn’t about fermentation at high temperature, which affects rate and flavor but not the sugar content itself.
