Features and Benefits
Formulation: Preparation of proanthocyanidic tannins extracted with water, instantaneously soluble.
Enological benefits:
- Prevents abrupt losses of colour matter (reaction with proteins) and helps to stabilise the colour.
- Has an antioxidant effect and helps to inhibit the laccase activity of botrytised grapes, protecting anthocyanins and improving their stabilisation.
- Facilitates the fining and clarification of red wines, thus improving their quality and stability over time.
Product Applications
Dissolve Pro Tanin R® previously in some must or wine, then add it into the tank during a pump-over or during a transfer to ensure perfect homogenization.
Dosage Guidelines:
- Healthy grapes: 10 to 30 g/hL, depending on grape ripeness.
- Botrytised grapes: 30 to 80 g/hL at tank filling, based on laccase activity determined by Botrytest®.
- Fining: 5 to 15 g/hL.
The dosage of tannins depends on the type of wine and the winemaking goals to be achieved. The Botrytest® is a useful tool for measuring laccase activity, which aids in determining the appropriate quantity of Pro Tanin R® to add to the must. Consult your enologist to ensure compliance with the oenological codex (OIV).
