Is Isinglass in beer vegan?
Depends on the brand
Depends — some cask beers are clarified with isinglass from fish swim bladders.
Also listed as: fish bladder finings
Why
Isinglass, gelatin and egg albumen are used as fining agents to clear beer and wine. Most modern craft and canned beers are unfined or use silica and PVPP instead.
