Beerblefish Betty Butter's Better Bitter

Company email (April 2017) "The Beerblefish Brewing Company makes 100% vegan beers. We are currently registering with the Vegan Society and are committed to making beer everyone can enjoy." [On followup about the other beers listed on their site:] "They are all Vegan, these are just the 4 we have registered so far with the Vegan society and are currently producing/have in stock but everything we make is vegan. We will be registering 10 this year with the Vegan society and rolling out more as we make them new or again."
