Guinness wasn’t vegan for over 250 years because it used isinglass, a fining agent made from dried fish swim bladders to clarify beer and remove yeast. Vegan drinkers campaigned for years with petitions, emails, and articles even though isinglass only appeared in trace amounts by packaging time. Diageo announced in 2015 they would eliminate isinglass with a new filtration system, and by 2017 all Guinness became fish free and vegan friendly. #guinness #beer #vegan #isinglass

Guinness wasn't vegan for over two fifty years, but in 2017 that changed. So the beer used to be produced with isinglass, a finding made from dried fish swim bladders. This clarifies the beer and pulls the yeast out of suspension. Vegan drinkers campaigned against this for years with petitions, emails, and even articles. By the time the beer is packaged, isinglass only appears in trace amounts, but this still wasn't enough for vegans. Then in 2015, Diageo announced it would eliminate Isinglass with a new state of the art filtration system. By 2017, all Guinness was fish free and vegan friendly, and it's been that way ever since.
