Five Star Super Moss Pro is a professional-grade kettle fining agent engineered to deliver unmatched brilliance and clarity to your finished beer. Formulated from highly concentrated, negatively charged Irish Moss (Carrageenan), Super Moss Pro acts as a powerful coagulant during the boil. It rapidly attracts and binds to positively charged haze-forming proteins, causing them to precipitate out of the wort during the "cold break." The result is a cleaner fermentation, improved shelf stability, and a crystal-clear professional appearance in everything from delicate Lagers to heavy IPAs.

  • Size: 3.5 lb. (1.58 kg) Resealable Bulk Jar
  • Active Ingredient: Premium Food-Grade Carrageenan (Irish Moss Extract)
  • Application: Kettle addition for hot-side protein coagulation
  • Efficiency: Highly concentrated—requires lower dosage rates than standard Irish Moss flakes
  • Clarity: Specifically targets "chill haze" and permanent protein haze
  • Compatibility: Safe for all beer styles and brewing equipment
  • Origin: Manufactured by Five Star Chemicals
Technician's Note: For maximum effectiveness, Super Moss Pro should be added to the kettle during the last 10–15 minutes of the boil. Unlike standard moss, this "Pro" version is processed into a fine powder for immediate dispersion. We recommend pre-mixing the powder with a small amount of cold water to create a slurry before adding it to the boiling wort; this prevents "clumping" and ensures the negatively charged particles are evenly distributed to grab as many proteins as possible before the whirlpool or cooling stage.
