The two beers are the first from a new brewing project at the St. James’s Gate brewery, Dublin.
Guinness Dublin Porter (3.8% abv) and Guinness West Indies Porter (6.0% abv) are both inspired by Guinness brewers’ diaries from 1769 and 1801.
Guinness Western Europe marketing director, Stephen O’Kelly, said: “As beer lovers’ tastes and the beer landscape itself evolves it is important we continue to stay at the forefront of beer innovation.
“Our brewers, at the core of the project, are passionate about pushing boundaries, whilst keeping true to the Guinness quality our customers know and love. Our two new beers are examples of this innovation and demonstrate the exciting things our brewers are continuing to do with stout.
“It’s an exciting time in the beer market, and we have made a big commitment to growing Guinness through innovation in the years to come. Guinness is only 255 years into its 9,000-year lease on the St. James’s Gate brewery in Dublin; these two new releases are the first taste of what’s to come.”
Guinness Dublin Porter and Guinness West Indies Porter carry an RRP of £2.20 and will be available in selected pubs and retailers from mid-September.
