Cahaba Brewing Co. Bronnie's ESBrittle is Not Vegan Friendly

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."
