Galalcool SP - 1 Kg

Tanin Galalcool SP P is a highly-purified gallic tannin preparation, for white and rosé wines.

TANIN GALALCOOL® SP is used during white and rosé wine maturation to: 

• Regulate the oxidation-reduction phenomena. 

• Regulate and limit SO2 additions thanks to its anti-oxidant action. 

• Increase protein stability. 

• Reduce natural enzyme activity causing residual oxidation (laccase, polyphenol oxidase) 

• Reduce bacterial development (as in Champagne production). 

• Improve clarification 

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