Different distillation methods

DISTILLATION   


Continuous distillation column: prohibited for Cognac eaux-de-vie

Distillation continue à colonne : interdite pour les eaux-de-vie de CognacThere are several distillation techniques used to produce spirits. Their differences stem from the way the distillation is carried out :

– continuous distillation is prohibited in the production of Cognac spirit but generally used to make vodka and most whiskies.


Double distillation in batches known as “repasse”: mandatory for making Cognac eaux-de-vie

Distillation discontinue dite « à repasse » : obligatoire pour les eaux-de-vie de Cognac– double distillation in batches, also called “repasse”: This is the traditional and long-established Charentaise distillation method and is the mandatory technique for producing Cognac. It is carried out in two successive “chauffes” (heatings) using a traditional “Charentais” still.

Double distillation results in better aroma concentration

Double distillation results in an aromatic eau-de-vie, unlike continuous distillation in column stills, which aims to produce a more neutral eau-de-vie.

The heating method, heating time and shape of the equipment, all have an effect on the quality of an eau-de-vie
