Vegetarians may be concerned to know that a gelatine produced from the swim bladders of fish is common in beer. Odourless isinglass makes beer more clear, bright and attractive. The Campaign for Real Ale (Camra) has asked brewers to look into alternatives, and Guinness announced last year that it would stop using isinglass. Camra has suggested that greater consumer awareness may lead to more pressure on brewers to change their practice and create more options for vegetarians.

Key Takeaways:

• Fish Bladder added to beer to make it clear
• Vegetarian bear without finings.
• Cloudy beer without fish additives

“Where once brewers skipping on finings was very much swimming against the tide, could we be looking at a situation where a flocculated beer filled to the gills with isinglass is a thing of the past?”
