Boulder Distillery is offering a refreshing return to sanity with Prüf vodka. No silly marketing gimmicks. No crazy flavors. No pretension. Just a clean, soft, super-smooth vodka with a subtle hint of sweetness that makes it perfect for sipping or mixing to perfection into your favorite cocktails. We start with pure Colorado rocky mountain water and use only the highest purity alcohol that has been distilled from corn, and produce a pure, simple, honest, vodka.
