Roederer Estate, founded in 1982 by Jean-Claude Rouzaud, then president of the parent company Champagne Louis Roederer, is a well-known California winery. It produces estate-bottled sparkling wines from Mendocino County's cool, fog-shrouded Anderson Valley. As the California outpost of Champagne Louis Roederer, Roederer Estate winery builds upon a centuries-old tradition of fine winemaking; it is considered one of the top sparkling wineries in the United States. Roederer Estate's sparkling wines are produced using estate-grown grapes exclusively from the winery's own 580-acre (230 ha) vineyard and special oak-aged reserve wines are added to each blend.
