In Ireland, there’s nothing more sacred than a perfectly served Guinness… Generous, creamy white foam, with a black/ruby robe underneath… But a British brewery has just launched a beer that is causing quite a stir in Ireland’s Irish pubs: a beer in the colors of Guinness… but in reverse.
The Team Toxic brewery in Liverpool, UK, has just released a strange beer that appears to be the negative of a Guinness. Named “Sinistral”, it quickly became known as the “Reverse Guinness”.
The cause: its black foam… and its white dress!
Presented as a white stout, it already seems to be arousing the curiosity of beer lovers.
And although this beverage is already causing controversy among some Irish purists, it’s already a phenomenal success in the UK! In fact, stocks are running out at a rate that exceeds all the British brewery’s forecasts.
At first, people immediately think of Guinness, and want to try an unusual beer. But the black foam is more of a gimmick… It’s not just a counterpoint to Guinness… The beer is well worth the detour. It’s the product of our brewery’s 20 years of craft beer experience. said the Team Toxic executive. People are amazed that it tastes so good.
It’s a success story that’s set to hit Irish pubs in the coming months…
What’s up? More Guinness? Or Reverse Guinness? Who will try it?
