Company email (April 2023)
"We do not use isinglass to clarify our beers. Instead, we use Biofine Clear, which uses silicic acid (SiO2), instead of animal-derived products like isinglass and gelatin. Therefore, our beers are vegan-friendly.
The only beers I can think of that we currently have available that would be exceptions are "Bronnie's ESBrittle" because we brewed it with pecan brittle--and there's butter in the brittle--and Even Morchata, because it was brewed with lactose sugar."
