Alphafloc paste

AB Vickers process aids

Alphafloc paste is a very concentrated form of isinglass which has to be converted into ready for use isinglass before addition to beer.

  • As with liquid isinglass, the resulting ready for use (RFU) is added to beer at the end fermentation to speed up maturation and improve filtration by removing yeast and protein particles. The main advantage of paste compared to RFU, is that it has a longer shelf life and can tolerate storage at temperatures up to 20°C.
