Is Harpoon beer suitable for vegans and vegetarians?
Yes, the only animal products used in beer production is isinglass (which is a dried swim bladder of a tropical fish from the Sea of China) or gelatin. These products are used typically in the production of ‘cask’ ales, the unfiltered ones served through a beer engine at bars that cater to beer connoisseurs. They’re very, very rarely used otherwise, although some brewers will use them to prepare a particularly hazy beer for filtration. At Harpoon, we never use either for our regularly produced beers.
