In fact, a number of alcoholic beverages contain, or are produced using, animal products. Many beers, lagers and wines are clarified or "fined" by adding isinglass or other animal products such as egg albumen and chitin, from the shells of crustacea.

The lack of labeling of these ingredients makes life difficult for those with food allergies, as well the UK’s three million veggies, and of course those who simply prefer a tasty pint without any ‘fishy’ additions.

Fortunately, some brewers (including many big names in the industry) don’t consider these animal products conducive to the pleasure of a pint. Many have established production processes that enable the finest beers and lagers to be produced without recourse to animal products.

Spokesperson for The Vegetarian Society, Collette Walsh, says: “We really welcome vegetarian friendly brewing at The Vegetarian Society (we’re partial to the odd pint ourselves) and wish to say cheers to those who are keeping up the good work by encouraging nominations from those who also appreciate a genuine veggie beer or lager.”
