TANIN VR COLOR (1 kg)

Instant dissolving (IDP Process) formulation of catechin tannins designed for red winemaking.

Qualified for the elaboration of products for direct human consumption in the field of the regulated use in oenology. In accordance with the current EU regulation n° 2019/934

Specifications and oenological applications

TANIN VR COLOR® has a high content of naturally active catechins (OxyProtect™ process) that allow the formation of chemically stable covalent bonds with anthocyanins (heterogeneous condensation tannin/anthocyanin ) for a superior colour stabilisation effect. To be used in case of tannin deficiency causing an unbalance of the tannin/anthocyanin ratio:

• Grapes harvested at sub-optimal phenolic ripeness.
• Grape varietals with a naturally poor tanin/anthocyanin ratio.
• Varietals that have colour management problems (extraction/stabilisation).
• Improves fining
