The cellars at Tesseron date back to the 13th century and were once part of a crypt of a local church. Tesseron Cognac is a new luxury cognac brand owned by the Tesseron family, which for more than a century has provided its old, rare stocks to the larger Cognac houses. The family holds one of the largest and finest collections of aged cognac reserves in the world and launched their own brand in 2003, releasing Cognacs only XO (which stands for extra old) and above in age. Made only in miniscule quantities, their Cognacs are incredibly rare and highly desirable.
