QUERTANIN Plus 500g

QUERTANIN® PLUS

QUERTANIN® PLUS is an ellagic tannin preparation used during the ageing process, which acts on the tannin structure and contributes to the balance of the wines.

It regulates redox phenomena during barrel ageing or micro-oxygenation.
Recreates in used barrels an environment rich in ellagic tannins, identical to that found in new oak.
Facilitates clarification.

DOSAGE:
The Oenological Code states that tannins "must not alter the aromatic characteristics and colour of the wine".
Dosage rates therefore vary according to the wine matrix and are determined after trials.
- Preservation of aromatic freshness in white and rosé wines: 2 - 5 g/hL (20 - 50 ppm).
- Ageing in red wines: 5 - 10 g/hL (50 - 100 ppm).

QUERTANIN® LINE
Various preparations with "stave wood quality" ellagic tannins extracted from oak heartwood or ellagic tannins extracted from oak heartwood and gallic tannins in soluble form
immediately (IDP), for the ageing of white, rosé and red wines.
- It regulates oxidation-reduction phenomena during maturation in barrels or during micro-oxidation.
- Thanks to the barrels used, the QUERTANIN® range allows the reconstitution of a medium rich in elagic tannins similar to a new barrel.
- After addition, it is recommended to carry out normal storage until clarification or preparation for bottling.
