QUERTANIN™ CHOC’ is a preparation of ellagic and gallic tannins that:

• Enhances wine structure and palate length.

• Regulates oxidation-reduction phenomena during maturation in barrels or during micro-oxygenation.

• Creates an environment rich in ellagic tannins in used barrels, similar to that of new barrels.

• Improves clarification.

After the addition, it is recommended to carry out normal rackings until fining or bottling preparation.

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).

• Red wine maturation: 5 - 10 g/hL (50 - 100 ppm).
