Vicfine

AB Vickers process aids

Vicfine is purified isinglass in convenient powder form. It is added to beer at the end of fermentation to speed maturation and improve filtration by removing yeasts and protein particles. For ease of use Vicfine in its standard form includes the necessary acid and preservative already blended.

  • The active component of Vicfine is isinglass (collagen). It is derived from the swim bladder of fish. Processing into finished form involves a regime of rigorous washing and sterilisation, followed by drying and milling.

    Collagen exists in solution as tightly bound triple helix strands which possess both positive and negative charged sites along their length. Beer treated with Vicfine requires shorter cold storage time, and has improved filterability.

    The sediments produced by Vicfine in the cold storage vessel are more compact, so less beer is lost during their removal.
