Eat, Drink and Be Murphy: An out-of-this world stout lands amid ski season MPNnow EAST BLOOMFIELD -- A man has time to think when coming up with specials to post on the large chalkboard that greets visitors to the Irish Mafia Brewing Co. So when he was presented with a Bristol Mountain trail map, owner Mark Mansfield thought that would be something cool to replicate on the board. Then, the wheels really turning, he thought, “It would be cool to do a beer with Bristol.” Cosmic Peak, a small batch collaboration between the East Bloomfield eatery and bar and Bristol, is available at both places, on draft and in cans.
