Tannin - VR Color, 100g to 1kg

Tannin VR Color

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 

Dosage: Colour Stabilization (30g/hl), Colloidal Structure (10g/hl)
