"All our bottled beers are suitable for vegans. We only use malt, hops and water in the production of our beer and we dont use any finings when bottling our beer, however our cask conditioned beers are not suitable for vegans. Bottles can be purchased direct from the brewery if you are ever in south yorkshire and i am in the process of linking with the web site my brewery tap so you will be able to purchase them online shortly."
