Founded in 2010 by a former U.S. Navy officer as San Diego's first production nano-brewery, Mike Hess Brewing, North Park operates its flagship 30-barrel brewhouse at 3812 Grim Ave. The tasting room shares the 30th Street brewery corridor with Belching Beaver Brewery North Park, anchoring a walkable craft-beer trail through the 92104 ZIP code. An elevated skybridge inside the taproom provides a direct sightline over the full brewing floor, letting visitors watch production runs from grain-in to packaging. Guests seeking a sit-down dinner nearby can walk to Siamo Napoli Restaurant on 30th St for wood-fired Neapolitan pizza. The brewery's most complex annual undertaking is its multi-stage charity beer festival, which coordinates releases across seven California locations and has directed over $100,000 toward pediatric cancer research and veterans' organizations.
