Dom Pérignon is only made in good harvest years.
In 1921 Dom Pérignon was first used as a brand, but it was not until 1947 that it became a champagne made in its own way from different grapes. The champagnes are made from well-ripened grapes and are a blend of pinot noir and chardonnay. The composition varies from year to year. After the second fermentation, the champagne is cellared for about eight years.
