RAIN Vodka is the only vodka made exclusively from organically-grown American grain. A super-premium vodka. RAIN is made from corn grown on Fizzle Flat Farms in Yale, Illinois. America's heartland...one of the few farms growing organic grain in the United States on a commercial scale. To achieve its exceptional smoothness, RAIN undergoes a rigorous production process, including quadruple distillation. Filtration is done with both activated charcoal and diamond dust -- the costliest form of filtration in the spirits business.
