Comes with citric acid.


The prime function if isinglass finings is to remove yeast cells from suspension after fermentation. Being densely positively charged, the collagen molecule rapidly attracts negatively charged yeast cells to form aggregates that are too large to remain in suspension and that, therefore, precipitate from the beer. Furthermore, many protein molecules have negative sites and are also precipitated by isinglass finings.   


Brupaks Isinglass Paste is a readily soluble form of isinglass designed to achieve clarification of beers.  

Method of Use  

To prepare this fining put 1 litre of water into a large mixing bowl or jug. Using a hand-held kitchen blender slowly mix in 70g of isinglass paste until fully dispersed. Add 7 g of citric acid and blend for a few minutes. Add a further 1 litre of water and blend for a further 10 -15 minutes. Store unused paste in a tightly sealed container. Ready mixed isinglass should be refrigerated and used within 4 weeks.

The prepared isinglass should be used at the rate of 200 - 500ml per 25 litres. Disperse thoroughly in either the conditioning tank or cask.
