Martell VS Single Distillery combines spirits from a single distillation source in France’s Cognac region for a richer and more intense expression of the Martell distillation sty le. Martell is the only great cognac house to double distill exclusively clear wines, from which all sediments have been removed, in order to preserve the authentic fruity aromas of the grapes and reveal their incredible subtlety. These are hallmarks of the Martell style.
