Effects of temperature on grapes

Wines from vineyards in warmer climates have more sugars and less acid, while wines from vineyards incooler climates have more acid and less sugar due to temperature fluctuations and sunlight patterns.

Grapes in warm climates lose their acid through respiration, while grapes in cooler climates will retain their acid.

For example, Pinot Noir grapes thrive in cooler climates and thus these wines are quite acidic, while Chenin Blanc grapes thrive in warmer climates and thus these wines are quite sweet. 

Some versatile vines can grow in both hot and cold climates, creating different flavors and texture depending on the temperature. Argentina’s Malbec grapes grown in cooler, higher altitudes—for example in Salta—create a robust, more acidic wine. Malbec grapes grown in warmer, lower altitudes—for example in Maipu, Mendoza—create a lighter, less acidic wine.
