Plan B Restaurants is launching its flagship beer, “Oh b’Haze,” brewed in partnership with Harpoon Brewery. The beer is an “assertively hoppy, well-balanced and aromatic unfiltered Pale Ale with an easy-drinking flavor and a vibrant amber color.” It will be available exclusively at its locations in Connecticut, Massachusetts, D.C. and Virginia. Names were solicited from the public, with a vote in early December to name the beer. The winning name was submitted by Nick Volte of West Hartford. The inaugural batch was brewed in Boston on January 11. The beer was scheduled to be tapped at all locations simultaneously on January 25 at 7 p.m., with the first 24 people to order it at each location receiving a custom pint glass.
