ZYR starts with clean, naturally filtered water. The water is then filtered five times in preparation for its marriage to the fermented blend of grains. After the five distillations of ZYR's mash, ZYR is filtered four more times using carefully selected birch tree charcoal granules to remove any remaining impurities and round out the taste. The fermented blend of winter wheat and rye is distilled five times. These stages ensure maximum clarity and purity in the product and in the incredibly clean taste. After these steps, ZYR is married to additional crystal-clear water, bringing the resulting spirit to 80-proof or 40% alcohol by volume.
