What is the minimum potential alcohol for harvesting in Champagne?

• A. 7%
• B. 11%
• C. 9%
• D. 12.5%

Answer: (C)

The key idea is how much sugar the grapes must have at harvest to make a viable base wine for Champagne. Potential alcohol is the amount of alcohol that would be produced if the must fermented to dryness, so it reflects grape sugar levels. Champagne regulations set a minimum of nine percent potential alcohol to ensure there’s enough sugar to reach a reasonable alcoholic strength during fermentation while maintaining balance with acidity. Grapes at seven percent would lack sufficient sugar for a proper base wine, while eleven or twelve and a half percent reflect higher ripeness and aren’t the required minimum. Therefore, nine percent is the correct threshold.
