For the past six years, Bauhaus has celebrated Oktoberfest with Schwandtoberfest, a Bavarian-style märzen lager with notes of caramel, toasted bread, and orange rind. The beer gets its name from the brewery’s owners, the Schwandt family. At Saturday’s event, there will be plenty of beer and a protein-heavy food truck menu from the likes of Gerhard’s Brats, Hoodlum BBQ Co., and New Bohemia. Or score some plant-based eats from Herbivorous Butcher. The party starts off with traditional tunes from the Brass Barn Polka Band at 3 p.m., followed by more jams from Static Panic (disco), Graveyard Club (indie synth), and Schwandt family band Viva Knievel (rock covers). Guests who ante up $30 for VIP tickets get a commemorative stein and two fills of the event’s namesake brew. All ages.
