Diageo’s brand Guinness has expanded its beer portfolio with the launch of Over The Moon Milk Stout variant in the US.

The beer variant was created at the Guinness Open Gate Brewery in Baltimore, Maryland, with 5.3% alcohol by volume (ABV).

Guinness Open Gate Brewery head brewer Hollie Stephenson said: “Guinness Over The Moon Milk Stout was born from an idea to make a beer that could celebrate our stout brewing expertise, speak to a wide spectrum of beer drinkers, and also convey the creativity and versatility of our brewing team here in Baltimore.

“The beer has notes of caramel, chocolate and a light roastiness that might remind some people of our historic stouts, however, it finishes with a sweetness characteristic of milk stouts, which we believe makes this beer very approachable and appealing to a wider audience.”

The variant offers a creamy mouthfeel, with hints of roasted malt and milk chocolate, as well as rich coffee and bold notes of roasted barley and hops.

Guinness Over The Moon Milk Stout is currently available in select US states including Baltimore, Boston, Washington DC and Philadelphia metro areas, as well as at the brewery’s taproom as a permanent addition to the Guinness family.

It will be available in six-packs of 12oz cans for a suggested retail price (SRP) of $10.99.

Guinness Over The Moon Milk Stout will be distributed across the US market for a limited time from November.

Guinness is brewed in 49 countries worldwide and from four main ingredients, water, malted and roasted barley, hops and yeast.
