KICK Carrageenan kettle finings are an effective way to improve flocculation and clarity in the kettle and throughout the rest of the brewing process. The active ingredient KICK Carrageenan is kappa carrageenan, a high molecular weight polysaccharide derived from red seaweed. When added near the end of the boil, kappa carrageenan binds to haze-forming proteins and other small particles and flocculates rapidly, resulting in improved wort and beer clarity.
