For a truly unique and traditional beer-tasting experience, visit Primitive Beer. This Longmont brewery is one of the few in the country dedicated exclusively to 100% spontaneously fermented, Belgian-style sour beers. Served still (uncarbonated) directly from the cask, their complex and nuanced beers are a true taste of old-world methods. The cozy, intimate taproom is a fun and fascinating place for the adventurous beer drinker to explore the wilder side of fermentation.
