Climate change & wine

Read the full story at Climate Central.

Fine wine production is likely to shift due to climate change. Among agricultural products, wine grapes are one of the most sensitive crops to variations in temperature and precipitation. 

In the United States, the average growing season temperature (April-October) has risen 2.0°F since 1970. 

Premium wine grapes can only be grown in places that support a delicate balance of heat and precipitation. Globally, wine grapes are grown in areas where the average growing season temperature (spring through fall) occurs within a narrow range of 18°F. For some grapes, such as pinot noir, the average temperature range is a much narrower 3.6°F

Other climate change threats to wine production include exposure to wildfire smoke, extreme heat waves, heavy precipitation, unexpected spring frosts, and drought. And with shorter and milder winters, insects and other grapevine pests are having longer life spans.
