VSSD is a smooth pioneering spirit by Martell made of 100% Martell VSOP Cognac, finished in Bourbon casks from Kentucky. At least 90% of the cognac must be comprised of those grapes, while an additional 10% can be made of other kinds, such as Semillon, Folignan, and more. Like Champagne, cognac must be made in the Cognac region of France.
The rules governing cognac are many, but essentially it must be double distilled and the final distillation must be between 67 to 72 degrees (alcohol by volume). It can take several decades for the strength to drop naturally to that which most of us drink cognac, 40 degrees. This natural process is by evaporation, the lost alcohol being known as ‘Part des Anges’, the ‘Angel’s Share’. To avoid waiting and to minimize cost, the producer dilutes the young cognacs, often adding sugar syrup and caramel.
