Ultra-premium vodka. Alcohol content is 40% ABV (80 proof). The vodka is produced from 100% premium, non-GMO European winter wheat and purified water processed to exacting neutral specifications. The spirit is 100% sugar-free with no added sugars, sweeteners, glycerin, or artificial texturizers. Distillation uses a hybrid method: the wheat mash is first processed through a modern multi-column distillation tower to generate a clean wheat spirit, then a portion is redirected into traditional coal-fired copper pot stills (including the distillery's original 19th-century copper still, Distilleerketel #1, the namesake of "Ketel One"). The heavy pot-still distillate is blended back into the crisp column spirit, then filtered over loose charcoal blocks and rested in tile-lined stabilization tanks. The appearance is completely crystal clear. No specific column specifications, charcoal block details, or resting duration are provided by the producer. The Nolet family has distilling heritage dating back to 1691. The brand was launched globally in 1983.
