Guinness won’t be hard to swallow for vegan beer lovers anymore.
Vegans have long been petitioning the Dublin stout’s use of an animal
product with several online campaigns. Its other ingredients include
barley, hops, yeast and water. Guinness has not yet revealed an
alternative to isinglass.
Pea extract can make suitable alternatives to isinglass, according to a
study in the Journal of the Institute of Brewing. The study indicated
that when pea protein was added to a commercial lager, it performed well
in comparison to beer with fish bladders. Another alternative is BioFine, a clarifying solution of colloidal silicon dioxide, a compound that helps remove yeast.
Guinness and other breweries are not required to state the use of isinglass on the bottle.
