Maker's Mark double distills its whiskey once in an all copper column still to produce low wine and again in a copper pot still to produce high wine. This added step removes impurities and produces a more refined sipping whiskey. Maker's Mark low wine is distilled off at 120 proof, while the high wine is 130 proof. This more expensive practice is used because it preserves Maker's Mark's mellow grain characteristics.
