The House of Clicquot is best known for its Yellow Label Brut non-vintage Champagne, which was a best seller in America prior to Prohibition. Veuve Clicquot also produces a Vintage, a vintage RosŽ, and a Demi-Sec. The firm's most prestigious Champagne, La Grande Dame, named for the Widow Clicquot herself, is made exclusively from the finest Pinot Noir and Chardonnay grapes picked from vineyards she purchased in the early 1800s.
