Alphaclar S

AB Vickers process aids

Even after filtration, beer contains proteins which originate from the raw ingredients. These proteins will react with polyphenols, also present in the beer, to form unacceptable haze. Alphaclar S is a single-use product which helps to remove the polyphenolic material.

  • Alphaclar S

    Alphaclar S is a single-use cross-linked polyvinylpyrrolidone (PVPP). It is a colloidal haze stabiliser which can increase the shelf-life of beer. Alphaclar S absorbs the haze-active polyphenols which would otherwise react with haze-active proteins in filtered beer to form colloidal haze during storage.
