Brut is French for "raw" and is used to describe sparkling wine or Champagne that has a dry taste. It's at the lower end of an ascending scale used to indicate sweetness, starting with brut zéro, brut nature, extra brut, and brut sauvage (all of which are bone-dry), then brut (dry), extra dry (which, oddly enough, is sweeter than brut), sec (slightly sweet), demi-sec (fairly sweet), and doux (definitely sweet). The three types of sparkling wine you're likely to see on the market are brut, extra dry, and demi-sec, with brut being far and away the most popular.
