据外媒报道，大多数人并不了解，啤酒里面其实含有鱼的成分。英国真麦酒促进组织（Campaign for Real Ale）现在一直在呼吁酿酒商研究替代品。
报道称，一般提到啤酒成分，大多会列举啤酒花、麦芽、大麦和水，外加酵母，几乎不可能想到鱼鳔，但其实啤酒可能都添加了鱼鳔制成的鱼胶。
早在19世纪，鱼胶便被作为澄清剂用于啤酒，让啤酒看起来更透亮、更吸引人，酿酒厂家普遍使用这种无味的添加物，从大规模生产的品牌到小型酿酒厂都一样。
部分原文报道如下：
Many people may not realise the beer in their pint glass contains a product made from fish. Now the Campaign for Real Ale （Camra） is calling on brewers to investigate alternatives for their drinks. But why is fish put in beer anyway?
Ask somebody to list the classic ingredients of beer and the chances are they will come back with: hops, malt, barley and water, with a bit of yeast thrown in for good measure.
