Aeronaut pours its famously experimental beers inside a cavernous converted factory a short walk from Somerville’s Union Square, and the taproom operates less like a bar than a neighborhood clubhouse with fermentation science underneath. Founded by science-grad-student homebrewers, the brewery keeps a deep draft list running from flagship IPAs to small-batch oddities, plus cider, wine, seltzer, and solid non-alcoholic options for the designated drivers.

The calendar is the real draw: live music several nights a week — jazz on weeknights, Americana and singer-songwriters in the mix — along with trivia, drag events, book clubs, and seasonal gatherings. Local art covers the walls, families wander through on weekends, and nobody hurries you out. It suits beer nerds and people who don’t drink at all in equal measure, which is exactly the point.
