Irish moss removes excessive protein from beer when ended at the end of the boil. It is composed of Chondrus crispus, a marine algae, and is an excellent method to reduce protein haze, improve flavor stability and overall quality in beer. Add 15 minutes before the end of the boil and chill rapidly to enhance protein precipitation.
Clarity-Ferm eliminates chill-haze in beer, increases shelf-life and improves consistency. It does not alter flavor or aroma and has no effect on head retention.
Clarity-Ferm works by preventing the precipitation of complexed polyphenols and proteins by hydrolyzing the sensitive (haze-active) polypeptides in the region where such hydrogen bonding occurs. The specificity of the enzyme ensures that no other beer parameters are affected. In addition to eliminating chill haze, Clarity-Ferm significantly reduces the gluten content in beers made with barley and wheat. A Clarity-Ferm treated beer made from barley or wheat usually tests below 10 ppm of gluten.
