There’s something new brewing at Guinness.

Guinness has just announced the release of two new beers, inspired by authentic recipes from Guinness brewers’ historic diaries from 1796 and 1801.

Guinness Dublin Porter and Guinness West Indies Porter are the first releases from a new brewing project at the St. James’s Gate brewery in Dublin. ‘The Brewers Project’ gives Guinness’ enterprising brewers license to collaborate, reinterpret old recipes and explore new ones.

The new Guinness Dublin Porter is sweet and smooth with malt and dark caramel notes. Originating from the diary entry of a Guinness brewer from 1796, the recipe is inspired by the ‘golden age’ of porter – the 1800s workingman’s beer in Dublin and London, where after a long day at work, this Guinness stout porter was always the choice.

The new Guinness West Indies Porter is hoppy with notes of toffee and chocolate, described as “complex yet mellow.” The recipe originates from an 1801 diary entry about brewing specifically to maintain freshness while Guinness is transported from one country to another. To guarantee the fresh quality, brewers created a porter with more hops and a higher gravity.

The new flavors came to life right inside Dublin’s St. James’s Gate, where some of the world’s most skilled brewers have been working away on refining their technique since the start of the Industrial Revolution.

Guinness’ Head of Innovation Nick Curtis-Davis noted in a recent press release that the new porters combine a rich heritage of 255 years of brewing with a legacy of innovation:

“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.”

This is an exciting time for stout lovers; the new porters, with their distinctive tastes, offer a fresh take on ‘the black stuff’ that’s been enjoyed for centuries, and only 255 years into the Dublin brewery’s 9,000-year lease, more innovative flavors are bound to come.

Guinness Dublin Porter and Guinness West Indies Porter will be available in selected pubs and retailers around Ireland starting October 1.

And for those of us who can't make it to Ireland for a taste test, in the coming weeks Guinness will introduce its first American Lager, Guinness Blonde, brewed in Pennsylvania.

The crisp lager has a floral, hoppy aroma, and is "twice as smooth, half as bitter, and 80% lighter in color than Guinness Draught," a press release said, though it stays true to the signature Guinness quality.
