CIA Greystone—St. Helena, CA

CIA Greystone is home to our academic programs in California, and you’ll be able to explore the beautiful and historic campus by taking a tour, dining in one of our restaurants, and attending an event.

CIA Greystone began as Greystone Cellars, built in 1889 as a gravity-flow cooperative winery serving upper Napa Valley grape growers, and was once the largest stone winery in the world. Purchased by the Christian Brothers in 1950, it then was used to increase production of wines, brandies, and ports under the direction of Brother Timothy Diener. CIA acquired the Greystone building in 1993 and the campus opened its doors in 1995, offering classes for food and wine professionals from around the world. The past comes alive all around you in Greystone’s main building, which is listed in the National Register of Historic Places. Learn more about Greystone’s history.
