Courvoisier has a traditional French Cognac heritage, but it also has many colorful and opulent associations. Courvoisier only uses Ugni Blanc grapes, and these are chosen from the four finest Crus of the Cognac region: Grande Champagne, Petite Champagne, Borderies and Fins Bois. The double distillation process is specific to cognac and takes place in a traditional Charentais pot still made of red copper. Courvoisier always uses French oak to create its ageing barrels. French oak is preferred by spirit makers worldwide because its age and finer grain woods add superb complexity and finesse to the cognac.
