Brut means “dry, raw, and unrefined” in French, and it refers to a style of Champagne that has less than 12 grammes of sugar per litre. Because of this, the Champagne is not very sweet and has a dry taste. The French word Brut means “dry,” so Brut Champagne is a dry sparkling wine. There are several different types of Brut Champagne, which can be told apart by how sweet or sour they are.
Brut should be served the same way as Champagne or any other sparkling wine: nice and cold.
