Nethergate Old Growler Dark Beer

Company email (April 2024) "All of our bottled beers are vegan (we don't need to fine them as the bottling process clarifies). However, are casks and Craft Lager are not - with the exception of Old Growler, which we leave unfined. We have tried the alternatives to isinglass, but find that they don't work well enough for a commercial product. We do always test any new products to market, so hopefully one day someone will come up with an alternative that works. Company email (October 2020) "All our bottled products are vegan friendly and our Old Growler in cask is also vegan friendly." Company email (circa 2011) "We use Isinglass to fine all of our beers in cask."
