November 2015)Guinness has been around for 256 years and, for the vast majority of that time, has never felt much pressure to appeal to vegans. Maybe it’s an Irish thing. But despite its illustrious history, the beer brand has decided there’s always room for a little change.
Last time I had one, which is probably 20 years ago, I thought it tasted of blood But I might give it a try again once they're no longer using fish bladders.
(Note: The article is inaccurate when it say vegans won't drink Guinness because they can't guarantee all the isinglass is removed in the final product. The real reason vegans won't consume it is of course that isinglass was used in the production process at all. It's irrelevant whether it's completely removed or not.)
