If there’s one thing that’s consistent about the beer scene, it’s a constant focus on innovation with an acknowledgement of our Midwestern history. This year’s Cave Fest at Casanova Liquors in Hudson highlights that. Take a little road trip to the historic Casanova Caves just east of the St. Croix River, and sample from a curated selection of cellared sour beers. The three-hour event will offer tastes of more than 75 sour and wild-fermented beers, plus there will be live music and appetizers to help keep some sense of sobriety among the revelry. This event is held sporadically; today’s will be the third the space has hosted in the past six years. Act now. Who knows when you’ll have your next opportunity to drink in a Wisconsin cave. 21+.
