High Rock is a premium, handcrafted vodka co-created by Dale Earnhardt Jr. and Amy Earnhardt in collaboration with Sugarlands Distilling Company. High Rock Vodka is triple filtered using the Lincoln County Process, made famous by Tennessee whiskeys, in which Sugar Maple Charcoal is used to filter out impurities. It is distilled from 100% corn, seven times. It is made using water from the Great Smoky Mountains in Tennessee and is 88 proof, a subtle nod to Dale Earnhardt Jr’s racing career.
