Finings are agents that are usually added at or near the completion of brewing beer to the fermenter. Their purpose is to remove unwanted organic compounds to help improve the beer clarity - as no one likes cloudy beer. They are also used for wine, cider, alcoholic ginger beer and non-alcoholic drinks such as juice.

What do beer Finings do?

Finings are processing aids added to unfiltered beer to remove yeast and protein haze. During fermentation yeast cells and beer proteins largely derived from the malt form a colloidal suspension that appears as a haze. A colloidal suspension forms when very small, charged particles are suspended in a liquid.

Do beer Finings stop fermentation?

Beer finings do not kill yeast. Some fining agents do cause yeast cells to flocculate and sink to the bottom of the fermenter, but there will still be plenty of active yeast present to carbonate the beer when it is bottled.
