Company email (May 2014):
"In our mainstay beers (Windvane, Ominous, Migration and Firefly Rye) we do not use any animal products/by-products. Our filter media is perlite, which is created by cracking volcanic glass.
I cannot guarantee that special one off releases wont contain things like honey or lactose, but you should be safe with the aforementioned beers."
