AUXILIARY FININGS
Auxiliary finings are added to cask beer at the end of fermentation, prior to isinglass addition to enhancing the clarification effects of isinglass.
Auxiliary finings contain protein-reactive materials such as silicic acid and/or polysaccharide. Auxiliary finings associate with haze-forming beer proteins. The isinglass complexes with these associations as well as the other proteins and yeast in the beer to enhance sedimentation and clarification.
Exhibits optimum speed of clarification
Maximum clarity
A typical treatment rate of 0.25 – 1 pints per barrel is recommended.
For both performance and commercial considerations it is advisable to identify the correct addition rate. This will vary from beer to beer.
