Isinglass and the Vegetarian Diet
Isinglass is a gelatinous substance obtained from the dried swim bladders of fish, particularly sturgeon. It is utilized primarily as a fining agent in the clarification process of beer and wine, helping to remove impurities and produce a clear final product. Although it is highly effective in these applications, its animal origin makes it unsuitable for vegetarians and vegans.
