Diageo said it intends to build a U.S. version of Dublin’s Guinness Open Gate Brewery in Baltimore County, Maryland following the momentum from Diageo Beer Company USA. The company plans a mid-sized Guinness brewery and visitor center with an “innovation microbrewery” at its existing Relay, Maryland production site. Tours, a taproom and a retail store are slated for the center. The new brewery would also serve as the home for new Guinness beers created for the U.S. market. If approved, construction is set for spring 2017 with the goal of opening in the fall, timed for the 200th anniversary of its U.S. import debut.
