Diageo North America selling off 45 acres surrounding Guinness Open Gate Brewery

The former manufacturing plant surrounding the Guinness Open Gate Brewery has hit the market as Diageo North America Inc.’s presence in Baltimore County continues to shrink. Diageo listed the 45-acre property — which does not include the Open Gate Brewery — at 5001 Washington Blvd. last week in another move toward downsizing at the site in Relay near Interstates 95 and 895. A leasing brochure from JLL, hired to handle the sale, says the deal aims to close by early October.
