Foamaid is a liquid form of propylene glycol alginate produced by the esterification of alginic acid. It is designed to give a trouble free method of enhancing and protecting beer foam.
Many years of development have been undertaken to identify the ideal blend of seaweed species required to yield the right quality of Alginic acid, and to optimise the critical esterification stage.
Foamaid stabilises beer in two ways:
This latter effect explains the positive role Drifoam plays in protecting beer foam from external contamination, particularly from grease and detergents.
