What role does climate play in wine production?

Climate plays an essential role in the quality and style of wines. The vine needs sun, heat, and water to produce ripe and balanced grapes. In the Rhône Valley, the climate combines good sunshine with the influence of the Rhône River, which helps regulate temperatures. Winds, such as the mistral, also help limit humidity in the vines and protect the grapes against certain diseases. Climate variations from one year to another directly influence the characteristics of the vintage. A hot summer can produce more concentrated wines, while a cooler year can yield lighter, more balanced wines. Climate is therefore one of the key factors determining a wine's identity.
