Opens and annies

October 24 | Grand Opening: New centrally located 32 North Brewing Company will throw open its doors and throw down with a Day One inventory of core beers such as Landfall Berliner Weisse, Fly By Night Milk Stout, and Nautical Mile IPA, plus specialties including Peanut Butter Cup Porter, a beer the brewmaster won praise for while at Karl Strauss Brewing Company. | 32 North Brewing Company, 8655 Production Avenue, Suite A, Miramar, 5 p.m.

October 25 | Two-Year Anniversary: If specialty beers like a bourbon barrel-aged barley wine, imperial pumpkin ale, and extra hoppy IPA aren’t enough to get you to Arcana Brewing Company’s Year Two fete, maybe food from MishMash Gourmet and a chance to test out your Halloween costume a day early will get you off the fence and into the steampunk-themed tasting room. | Arcana Brewing Company, 5621 Palmer Way, Carlsbad, Two Sessions (2 p.m., 6 p.m.)

October 25 | One-Year Anniversary: For fans of Barrel Harbor Brewing Company looking to celebrate its first year in business, doing so is essentially just another day in paradise. Admission is free and the rules are simple — seven bucks gets you a beer of your choosing poured into a commemorative pint glass. Some of the best things in life are the simplest. | Barrel Harbor Brewing Company, 2575 Pioneer Avenue, Suite 104, Vista, 12 p.m.
