WGBH is hosting its second annual Craft Beer Festival on Saturday, July 12th at their Allston studios. This year’s event will feature 21 breweries from all around New England, including local powerhouses Harpoon and Sam Adams, along with newcomers, like Somerville’s Aeronaut Brewery. Delicious bites will be served up by food truck favorites Roxy’s Grilled Cheese and Mei Mei Street Kitchen. Attendees will be able to taste beers to their heart’s delight, while the aficionados will have a chance to participate in blind tastings and fermentation tutorials. There will be two live bands keeping the good vibes going and plenty of vendors with all kinds of home-brewing gear for sale. Tickets are $40 for WGBH members and $50 for non-members and both can be purchased online. The event opens at 7:00 and wraps up at 10:00pm.
