What does brut mean?
|Brut is a term applied to the driest Champagne and sparkling wines. Brut wines are drier which means they contain less residual sugar than those labeled “extra dry.” Extra Brut denotes a wine that’s extremely dry, sometimes totally dry. Totally dry sparkling wines (those that aren’t sweetened with a little dosage) are also sometimes called Brut Nature or Brut Integral.|
