QUERTANIN™ PLUS is a preparation of ellagic tannins used in aging, which acts on the tannic structure and contributes to balance in wines.

• Regulates redox phenomena during barrel aging or micro-oxygenation.

• Recreates an environment rich in ellagic tannins in used barrels, identical to that found in new oak.

• Facilitates clarification.

DOSAGE:

It is specified in the Oenological Codex that tannins “must not change the olfactory properties and the colour of wine”. The dosage rates will therefore vary in function of the wine matrix, and shall be determined after trials.

• Preservation of aromatic freshness in white and rosé wines: 2 - 5 g/hL (20 - 50 ppm).

• Ageing of red wines: 5 - 10 g/hL (50 - 100 ppm).
