Yards Brewing Co. put up a giant, 16-foot Christmas tree in its tasting room yesterday. To get it properly trimmed, they’re offering a tasty incentive. Bring an ornament — homemade preferred — to the brewery, hang it on the tree and receive a free beer. It’s that simple. In addition to its regular offerings, this week Yards is pouring its ultra-rare Trubbel de Yards, a strong Belgian-style Dubbel that’s been seldom seen since the late 90s.
