Domaine Didier Champalou is in the Vouvray appellation in the Loire Valley, France. Both Catherine and Didier came from vigneron families, and both studied viticulture in college followed by working at estates around the world. But in 1983 the husband and wife team started their own 62-acre estate where they grown the region’s Chenin Blanc and make several styles of Vouvray, including dry, off-dry and botrytized, or sweet. About 10,000 cases are produced annually. The estate’s wines are extremely popular in restaurants in the U.S. and France.
