Why might harvest timing be adjusted due to weather?

• A. To preserve acidity
• B. To maximize sugar
• C. To increase color
• D. To reduce yields

Answer: (A)

Grapes for Champagne are kept in balance by timing their harvest to what the weather is doing. The acidity in grapes is a key driver of freshness, structure, and how the wine will age. When the weather turns warm, sugars rise quickly, but acids tend to fall. If you wait too long in hot conditions, the wine can lose the crisp, bright acidity that sparkling wines rely on, making it feel flat or heavy. So, harvest timing is adjusted to preserve acidity—picking earlier when heat is forecast helps lock in the necessary acidity while still achieving enough maturity.

In cooler weather, you might push harvest a bit later to build sufficient sugar, still aiming to keep an appropriate level of acidity, but the central idea is to protect acidity as weather shifts, because that balance is what keeps the wine lively and suitable for the traditional sparkling style. The other options aren’t the primary reason: weather-driven changes in sugar are a factor, but the goal here is preserving acidity; color isn’t a priority for these grapes; and adjusting harvest to reduce yields isn’t the main driving reason tied to weather.
