Polyclar™ Brewbrite stabilizer – Wort Clarifier 50g.

Polyclar™ Brewbrite stabilizer from Ashland is a highly effective, proprietary wort clarifier and beer stabilizer. It is an optimized composite of purified food-grade carrageenan and specially modified polyvinyl polypyrrolidone (PVPP) making it the ideal upstream, single-addition product for stabilization protection against chill haze and permanent haze.

Non-biological haze formation results primarily from the hydrogen bonding between haze-producing proteins and the polyphenol constituents of beer. Non-microbiological products (NMPs) act as templates on which these protein-polyphenol complexes may attach, thereby accelerating haze development in beer. Kappa-carrageenan, a hydrocolloid extracted from red seaweed, is very effective at reducing the size of NMPs in wort. These comprise protein, polyphenol, polysaccharide and other materials.

Polyvinyl polypyrrolidone, or crosslinked PVP, is a synthetic polymer that specifically binds to haze-producing polyphenols. It complexes with specific polyphenols in beer via hydrogen bonding and is then removed during filtration.

To achieve colloidal stability in beer, it is necessary to reduce these protein-polyphenol complexes, or prevent them from forming. Polyclar Brewbrite beer stabilizer does both as it reduces the size of NMPs in the wort and removes polyphenols.

Polyclar Brewbrite wort clarifier and beer stabilizer benefits and features include:

Upstream wort clarification and beer stabilization with a single addition of the product to the wort

Effective and highly selective removal of haze-producing polyphenols

Protection against chill- and permanent-haze development

Improved fermentation characteristics

Increased wort collection

Prepared as a 10% slurry in room temperature water

Removed with the trub

Longer filter-run lengths

No negative impact on foam, flavor or other quality parameters

Complete insolubility in all types of beer
