🍷 Chalone Vineyard

Chalone Vineyard is located in the Chalone AVA south of San Francisco, California, United States, on an unusual geological formation called the Gavilan benchland. The soil is rich in limestone and calcium carbonate and also contains a significant amount of decomposed granite. This soil has a mineral composition similar to the Champagne region of France. Chalone is situated in an arid chaparral environment, in which temperatures can vary as much as 50°F in one day. The climate is very dry, only 12 to 14 inches (360 mm) of rain fall per year. These factors combine to create a unique terroir, the signature profile of a wine growing region.
