The truth: NOT ALWAYS TRUE. Next time you are with some friends drinking some beers, say: “So, do you guys know what isinglass is?” When they say no, you follow up: “Oh, well, it’s just a substance obtained from the dried swim bladders of fish used to filter beer!” And then CHUG your beer and belch and say: “Does that smell like fish?” So, if you follow a strict vegetarian or vegan diet (is there a non-strict vegan diet?), you’ll want to investigate whether your favorite brewery uses isinglass or some other weird animal product in their purification process. Barnivore.com has an exhaustive and well-documented list.
