Specifications and oenological applications

TANIN GALALCOOL® is a highly purified extract of gallic tannins, with physical and chemical properties particularly well adapted to white and rose must vinification.

• Reduces natural enzymatic oxidation activity (e.g. from laccase or polyphenol oxidase), complementing the activity of SO².
• Complements bentonite use to precipitate unstable proteins.
• Regulates and minimizes the use of SO² due to its excellent anti-oxidant activity.
• Improves clarification.

Protocol for use

Oenological conditions

• Protection from oxidation.
  
• Botrytis infected harvest: laccase activity > 2 U/mL.
  
• Sparkling wines (Traditional method): add TANIN GALALCOOL® during tirage bottling for the secondary fermentation..

Dosage

• Oxidation & Botrytis protection: 5 - 20 g/hL (50 - 200 ppm).
• Bottling of sparkling wines: 2 - 4 g/hL (20 - 40 ppm).

Implementation

• Thanks to its granulation, TANIN GALALCOOL® can be directly sprinkled onto the wine, during homogenisation or a pump-over.
• On a Botrytised harvest, add a 10% TANIN GALALCOOL® solution after crushing, and in small doses during pumping into the press.
• For sparkling wines, add a 10% TANIN GALALCOOL® solution to the “mixtion of tirage” (blend of sugar and yeast).

Storage recommendation

• Store above ground level in a dry area not liable to impart odours. Ensuring stock is kept at a moderate temperature, in its original, unopened packaging.
• Optimal date of use: 4 years.

Packaging

• 1 kg bag
