Moët et Chandon or Moët, is a French winery and co-owner of the luxury goods company Moët-Hennessy Louis Vuitton (LVMH). Moët et Chandon is one of the world's largest Champagne producers and a prominent Champagne house. The company holds a Royal Warrant to supply champagne to Queen Elizabeth II. Moët et Chandon was established in 1743 by Claude Moët, and today owns more than 1,000 hectares (2,500 acres) of vineyards, and annually produces approximately 26,000,000 bottles of champagne.

Dom Pérignon is a brand of Champagne produced by Moët et Chandon. It is named after Dom Pérignon, a Benedictine monk who was an important quality pioneer for Champagne wine but who, contrary to popular myths, did not discover the Champagne method for making sparkling wines. Dom Pérignon was the first prestige cuvée, an idea proposed by Englishman Laurence Venn. The first vintage of Dom Pérignon was 1921 and was only released for sale in 1936. Dom Pérignon is a vintage Champagne, meaning that it is only made in the best year, and all grapes used to make the wine were harvested in the same year.
