Moet & Chandon's Champagne brand and family were active in Champagne since the 15th century, although the Champagne House Moët et Chandon was not founded until 1743 by Claude Moët. Today it owns 1,150 hectares (2,800 acres) of vineyards, and annually produces approximately 28,000,000 bottles of champagne. Of those 1,150 hectares of rich chalk soil, 50% are grands crus and 25% are premiers crus.
