Guinness deemed suitable for vegans as fish bladders are no longer to be used in stout making
Vegans will finally be able to enjoy a pint of the black stuff for the first time in Guinness’ history as the company will no longer use fish bladders in their stout-making process.
The company announced that it will be updating their infiltration system from isinglass, which is a by-product of the fishing industry used to settle yeast faster.
A spokesperson from the Guinness said: "While isinglass is a very effective means of clarification and has been used for many years, we expect to stop using it as the new filtration asset is introduced."
Isinglass has been used throughout Guinness’ 256 year history traces of fish bladder remain in the finished pint of stout.
"We are conscious that its use may represent a barrier to consumption of our products to some,” the spokesperson added.
“As part of our ongoing efforts to further improve the way we make our products, we are seeking alternatives to isinglass."
The move by Guinness follows years of campaigning from vegan organisations, who were unsettled by the fact that Guinness is not required to state the traces of fish present in the finished product.
