(Newser) – After pressure from beer-chugging vegans who were behind a long-running campaign and several online petitions, Guinness has elected to change its 256-year-old recipe and remove isinglass—a gelatinous byproduct of fish bladders that helps filter yeast particles—from its brewing process, reports CNN Money. Guinness now says it will use a new filtration plant to be installed at its flagship brewery in Ireland at some point in 2016, reports the Independent, while it doesn't yet plan to change its other breweries scattered across 49 countries.

The company had previously responded to requests to remove isinglass by saying it provides a "very effective means of clarification," and as recently as January said in a company email to Barnivore, which tracks animal ingredients in adult beverages, that it had yet to find a replacement "as effective and as environmentally friendly." No word yet on what it's come up with. Parent company Diageo has said that competition from microbreweries flattened its sales in 2015. Meanwhile, many popular beers, including Anheuser-Busch, Heineken, and Miller, are deemed vegan-friendly by Barnivore.
