The Branson XO Grande Champagne is their most exquisite product. The minimum aging requirement for XO cognac is 10 years, but the eaux-de-vie in this expression range from 10 to more than 25 years. All of the juice is from Grande Champagne. It is distilled using a pot still from the 1800s. The 80-proof spirit made Wine Enthusiast's "Top 100 Spirits 2020" list.
