100ml bottle and 1 litre bottle Isinglass finings
Added to beer for rapid settling of yeast. Increases stability and shelf life of beer.
Originally used in the British brewing industry to accelerate the fining or clarification of cask beer.. The finings flocculate the live yeast in the beer into a jelly like mass forming a sediment at the base of the cask. Always used post fermentation.
Instructions: Dissolve 100ml in approximately 250ml of beer. Add this back to a 25 litre brew in your fermenter. Stir.
Leave to settle for 24-48 hours before bottling.
