As Senator Ben Cardin toured the Heavy Seas brewery Friday, July 19, he was nearly splashed with a great deal of pumpkin ale being pumped into a bourbon barrel not far from where he stood with Hugh Sisson, Heavy Seas' founder. After the narrow miss, the senator and Sisson, flanked by a covey of distributor reps, investors, and reporters, traversed through the Halethorpe brewery's recent expansions: a 96,000-cubic feet cold room; rows upon rows of storage racks, stacked with bourbon barrels and packaging; a new tasting room to hold a new 24-foot mahogany bar, where the tour ended. A table was set up with cans of Loose Cannon and Davy Jones' Lager on ice. Sisson mentioned plans for an additional bar attached to the cold room. "There's a lot of drinking going on here," a legislative aide for Councilman Tom Quirk muttered to an acquaintance. Amid clicking cameras, Sisson pointed out a photo of Cardin tapping a cask of beer at the grand opening of Sisson's, the famed South Baltimore brewpub, in 1989.
