Guinness Open Gate Brewery

Diageo’s impending closure of the Guinness Open Gate Brewery in Halethorpe, Maryland, will lead to 174 permanent layoffs, effective November 1, according to a WARN Act notice filed October 1 with the state.

The Guinness Open Gate Brewery in Baltimore will permanently close to the public on November 1, Diageo shared today.

The Guinness Open Gate Brewery in Baltimore, Maryland invites the community to celebrate its fifth anniversary from Thursday, August 3 through Sunday, August 6. The five-year anniversary tradition theme is wood, representing the craftsmanship, strength and deep roots that the brewery has grown since opening on August 3, 2018.

More than 300 winners were honored during the Brewers Association’s (BA) 2023 World Beer Cup (WBC) during Craft Brewers Conference in Nashville this week. Guinness Baltimore Blonde – the signature offering of brewing operations at Diageo’s Relay, Maryland-based production facility – has become such a local icon that one Baltimore County official wants to invest $500,000 in a local brewer to keep the beer flowing, according to the Baltimore Banner.

Nearly five years after it opened, Diageo will cease the majority of production later this spring at what was its first Guinness production brewery in the U.S. since 1954.
