Abstract
Carrageenan, sourced from seaweed, has long been used in brewing to help remove excess protein from wort and to help produce bright beer. Its highly negative charge helps it to adsorb excess protein in wort and settle it out as cold break. This paper reviews the structure, chemistry, function, production, and use of carrageenan in brewing.
