@LordMordred With wine I know that like 50% of it isn’t vegan, so I check it against Barnivore and have a few known widely-available products that I buy.
Beer on the other hand is vegan 90% of the time. It’s bread soda. The odds are in your favor. So yeah it’s a little risky, but it typically is somewhat obvious if there are allergens in it. This particular beer didn’t set off my vegan senses until later.
