RockFilter Distillery sits on Maple Drive in Spring Grove, Minnesota, a small town tucked into the bluffs of southeastern Minnesota’s driftless region. Founded by Tom Klinger and his team, this craft distillery opened its doors in 2013 with a mission to create small-batch spirits using local ingredients and traditional methods. The operation centers around a custom-built copper still system housed in a converted industrial building that they’ve transformed into a working distillery and tasting room. Klinger’s journey into distilling began as a hobby that evolved into a passion for creating quality spirits. The team at RockFilter focuses on producing vodka, gin, and whiskey, with particular attention to sourcing grains from local Minnesota farms when possible. Their approach emphasizes hands-on production methods and careful attention to each batch, allowing them to maintain quality control throughout the process. Visitors to RockFilter can experience both the production side and finished products in their on-site tasting room. The distillery offers tours that walk you through their process from grain to bottle, and tastings that showcase their current lineup of spirits. The atmosphere balances the industrial heritage of the building with the warmth of a family-run operation, creating a space where you can learn about distilling while sampling the results of their work.
