Stringers No. 2 Stout (cask conditioned) is Vegan Friendly

Update, March 2012:
Company website shows Dry Stout in bottles as vegan friendly: http://www.stringersbeer.co.uk/#bottle_section

Previous update:
We produce a number of beers, some of which I believe to be suitable for vegans. The only animal product which will find its way into any of our beers is piscine isinglass.

As far as cask beers go: While some brewers manage to avoid the use of isinglass by relying on a highly flocculent yeast or by sending beer out with rather low levels of residual yeast, we've found that neither of these approaches will give us beer that reliably conditions in cask and suits normal cellar operations. Basically, we've found it pretty near impossible to sell pale, cask-conditioned beer unfined, so we do normally use isinglass in these products. On the other hand, our darker beers work well without finings, so we don't put any in, making them suitable for everyone, including vegetarians and vegans.

The cask beers of ours I'd suggest would be the "No. 2 Stout" or the "Dark Country". And possibly other, occasional beers, which we'd identify on our website as being suitable for vegans.

Regarding bottled beers: We're planning to start marketing a small range of bottle-conditioned beer and we hope that these will all be unfined. At present our two filtered, carbonated beers are the "IPA" and the "Dry Stout". Of these, the "Dry Stout" is unfined, hence suitable for vegans.

Any utensils or containers that may have been in contact with isinglass will, as a matter of course, be cleaned thoroughly after such use, and before being used for anything else.

We're always looking to improve our products, and for me this would include moving away from the use of isinglass where we can."
