Isinglass

Isinglass is a substance obtained from the dried swim bladders of fish. It is a form of collagen used primarily for the clarification or fining of some beer and wine. It can also be cooked into a paste for specialized gluing purposes.

History

The use of isinglass in beer and wine clarification has a long history, with the first documented use in English brewing in the 19th century. The process of using isinglass in alcohol clarification is known as fining, and is used to remove yeast and other solids from the drink.

Production

Isinglass is produced from the swim bladders of fish, particularly sturgeon and cod. The bladders are harvested, cleaned, and dried before being sold for use. The production process is labor-intensive and requires a high level of skill.

Uses

Isinglass has a variety of uses, primarily in the clarification of beer and wine. It is also used in the production of certain types of glue, in the restoration of old parchments, and in the making of certain types of jelly.

Health concerns

There are some health concerns associated with the consumption of isinglass, particularly for those with fish allergies. However, the amount of isinglass remaining in beer or wine after the fining process is typically very small.
