Isinglass
A fining agent made from fish swim bladders, commonly used to clarify beer and wine.
Why this is a critical point
Isinglass comes from fish swim bladders, so the material itself is generally halal. It is, however, most often used to clarify beer and alcoholic wine — the finished product still warrants scrutiny because of its context of use, not because of the isinglass itself.
Also known as
Isinglass, Fining agent, Bahan penjernih minuman
Commonly found in
Clarifying beer, wine, and some packaged juices.
Halal alternative
Plant-based fining agents such as bentonite or carrageenan in non-alcoholic beverage products.
