RED, ROSÉ AND WHITE WINE - AGING.
QUERTANIN® INTENSE is preparation of high quality toasted oak tannin. Enhances wine mouthfeel, roundness and palate length. Stave wood quality ellagic tannins, extracted from oak heartwood for post-vinification use in red, rosé and white wines.
Used during fining, QUERTANIN® INTENSE NF is an ellagitannin preparation to enhance 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.
• Preservation of aromatic freshness in white and rosé wines: 0,5 to 2 g/hL (5 - 20 ppm)
• Red wine maturation: 3 to 10 g/hL (30 - 100 ppm)
