Diageo shuts Guinness Baltimore brewery, leaving 174 jobs and one US site
Guinness is closing its Open Gate Brewery in Halethorpe, Maryland, effective November 1, 2026. The shutdown eliminates 174 positions held by Aramark employees and leaves the Chicago facility as the brand's only remaining U.S. location. The decision stems from a $1 billion restructuring plan by parent company Diageo, shifting focus away from experimental brewing toward core products like Guinness Zero.
