Sly Fox Brewing is Vegan Friendly

VEGAN REVIEW:
Kevin M says "Their dry irish stout. which goes by the name O'Reilly's Stout, has a similar style to Guinness, but has bested it in many local blind taste tests."

UPDATE! DEC 2009
"We do not use any animal products in our beers with the exception of our cask beer. For beer served from a cask, we use isinglass finings."

Company Email:
"We use Isinglass, but only for our cask conditioned beers. All our normal draught and packaged beers are not made with Isinglass.
Almost all beer is filtered with Diatomaceous earth."
