Handcrafted in small batches, using traditional recipes at the Nolet Distillery in Holland. Founded 1691.
Is the "ultimate" in the world of vodka… In a class by itself. For generations, the Nolet family in Holland has been distilling the finest spirits using techniques and recipes perfected by Jonnes Nolet and his successors since 1691. Ketel One, named after the original distilling ketel number one, is distilled in small batches using traditional pot stills, filtered through charcoal and rested until perfect. This costly, painstaking yields a limited quantity of Ketel One Vodka that possesses a refined elegance, distinctive smoothness and unmatched quality.
