Brewtan® Gallotannins

100% natural gallotannins specially designed for haze reduction in beer.

Brewtan B, Brewtan C, and Brewtan F are 100% natural gallotannins specially designed for the brewing industry. These tannins improve the clarity and shelf life of beer by reacting with haze-sensitive proteins (proteins rich in proline) and SH-group-containing proteins by adsorption and precipitation. They also chelate iron, thereby inhibiting the Fenton oxidation reaction.

  • Brewtan B:
    • Used in the mash tun as iron chelator (2–6 ppm)
    • Used in brew kettle for kettle fining ( 2–6 ppm)
  • Brewtan C: Used in aging tanks for colloidal stability (5–8 ppm)
  • Brewtan F: Used in the filtration process for colloidal stability (1–2 ppm)
