According to Koonal it can be. He’s even explained why a beer he likes is not vegan and tell us where to get vegan beer from.
A few months ago, I was very disappointed to learn that isinglass finings (obtained from fish bladders) are used as a processing aid in the brewing industry to accelerate the clarification of beer – i.e. to make it less cloudy. This means that most real ales (hugely superior in taste to fizzy, chemical-infused lagers) are not vegetarian/vegan.
However, I recently learned that all beers produced by the Samuel Smith’s brewery (with the exception of Old Brewery Bitter) are 100% vegan. Samuel Smith’s operated pubs are inexpensive and charming, and
are located throughout the UK, including several within central London. They can get very busy, but I would certainly recommend a visit as they have a very traditional feel to them, and they don’t sell spirits or soft-drinks produced by any of the large corporate manufacturers.

Do you know about any other vegan or non vegan products?
