The brewery’s innovation hub has been active at its St. James’s Gate, Dublin for over a century.
From early December, however, visitors will now be able to meet the brewers and discuss their work, as well as to sample a wide range of exclusive beers.
Guinness will be sharing early small batch versions of experimental beers, together with a selection of Guinness beers from around the world which have never been available in one single location before.
More familiar brews, including the iconic Guinness stout, Hop House 13 Lager, and Guinness West Indies Porter will also be available.
Guinness brewer Peter Simpson said: “We feel extremely lucky to have free rein to regularly explore and create new beers in small batches.
“There is huge interest in beer nowadays and my fellow brewers and I are excited to share our experimental beers, which until now, have never been tasted outside the brewery.
“We are also really looking forward to collaborating with beer enthusiasts from around the world at The Open Gate Brewery in the future.”
The Open Gate Brewery will be open to the public every Thursday and Friday night from 5.30pm until 10.30pm.
