Auxiliary finings

AB Vickers process aids

Auxiliary finings are added to cask beer at the end of fermentation, prior to isinglass addition to enhance the clarification of isinglass.

  • Auxiliary finings contain protein – reactive materials such as silicic acid and/or polysaccharide. These associate with haze forming beer proteins and in turn complex with Isinglass as well as other proteins and yeast to enhance sedimentation and clarification.
