One famous brewer is about to make a lot of people very happy.
Ireland's famous stout, Guinness, hopes to stop using isinglass, a gelatin obtained from fish, in its filtration process for the first time. This will provide a pint that's suitable for vegetarian and vegan consumers.
Guinness is in the process of installing a new filtration system at St James's Gate brewery in Ireland that once in place will remove the use of isinglass from the brewing process.
The plan is to have the system running by late 2016, with the new brew on the shelves for consumers to buy soon after.
