Cognac Distillation Process: The “Two-Stage” Distillation Is Comprised Of The “Brouillis”, Followed By “La Bonne Chauffe” (Animated Video)
The distillation method has not changed since the birth of Cognac. The special Charentais copper stills “à repasse” that were used then are still in use today. Cognac distillation is performed in a two-stage process: Stage one: a first distillate is obtained, referred to as "brouillis", with an alcohol volume of 28 to 32%; Stage two: The "brouillis" is returned to the boiler for a second heating, known as "la bonne chauffe".
