Black Sheep Brewery has some vegan options

Company email (July 2021)
"Unfortunately, our cask ales are not suitable for vegans due to the finings we use.

However, our bottled ales, cans and kegged beer are perfectly suitable. . . We offer a large range so you will have plenty of great ales to be able to enjoy"

Company email (February 2017)
"For us, its relatively simple. Our casks use isinglass for clarification, so are not. Our bottles and kegs are filtered so do not use isinglass."

Company email (August 2013):
"We use isinglass finings in the processing of our cask conditioned beers so they are unsuitable for vegans. However it is not used for our bottled products which are therefore suitable."

Company email (April 2011):
"Black Sheep bottled beers are indeed suitable for vegans. Unfortunately due to the use of isinglass finings to clarify our cask beers, they are unsuitable."

Company email (May 2010):
"Thanks for your inquiry about the suitability of our beers for vegans. Our draught cask ales all use isinglass finings derived from fish swim bladders for clarification and therefore would not be suitable. However our range of bottled beers are filtered and hence due not use isinglass, therefore are animal ingredient free."

Note from Cindy
"After receiving an email from the company I am happy to say their bottled beer is vegan and it's quite tastey too! Beware, their cask beers are fined with isinglass."
