• Protects wine with regards to oxidation (more aromatic intensity)

• Eliminates reductive odours.

Quertanin - 25g to 500g

To introduce oak character in wines, an addition of pure oak tannin may be beneficial. Quertanin is extracted from oak trees grown in the Limousin region of France.

Quertanin contributes wood nuances without toasty or smoky character.

This finishing tannin is a strong anti-oxidant and can increase the complexity of the wine finish. It will not, however, increase middle palate.

Quertanin contributes to color preservation, especially when old barrels are used during aging.

 

Dosage: Red Wine (2-20g/HL), White Wine (2-20g/HL)
