Barney's Red Rye (bottle/keg) is Vegan Friendly

"The only beer we put lactose in is Marshmallow and we don't add any non-vegan finings to our bottled beers. We used to put lactose in the Sherbet but we don't anymore, however the labels weren't updated to reflect that so if you order some Sherbet don't panic if it lists lactose on it."
