The Ireland company uses fish bladder also called as isinglass in its brewing process to make yeast settle faster and clarify the liquid.

‘Cheers, Vegans! Time to drink up as the world famous Guinness beer to become vegan-friendly. The company has decided to remove fish collagen from its brewing process and replace it with a non-animal filtration system.’

The fish bladder also called as isinglass is actually a type of collagen. It is unsuitable for vegans as it is an animal product. The company is finding out ways to filter beer without using animal products and the new technique will be implemented from 2016.




"Whilst 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. We are conscious that its use may represent a barrier to consumption of our products to some. As part of our ongoing efforts to further improve the way we make our products, we are seeking alternatives to isinglass,” said a Guinness spokesman.
