Ketel One Vodka is distilled from 100% wheat and made at the Nolet Distillery in Schiedam, the Netherlands. It is distilled in copper pot stills, filtered over loose charcoal, and rests in tile lined tanks until ready. Ketel One Vodka is named after the original copper pot still, "Distilleerketel #1" and is handcrafted in small batches. The Nolet's family sense of tradition and quality combined with an unconventional promotion campaign assured that the vodka from the Netherlands is taking the world by storm. Ketel One Citroen flavoured vodka begins with Ketel One Vodka, infused with the essence of four different types of lemons, and two types of limes to enhance the freshness.
