Powdered Tannins Dilution Procedure

Weighing the tannins

Measure the required amount based on the recommended dosage.

Example:

• Must or pre-fermentation: 5 to 30 g/hL.
• Red wine: 4 g/hL (See the correspondence table for your trials with the decision aid kit  (click).

Preparation of the solution

• Dissolve the tannins in 10 to 20 times their weight in water or wine.

Recommended: Use warm to hot water (50-70 °C / 122-158 °F) for faster dissolution.

• Stir vigorously to properly disperse the tannins.

Rest and homogenization

• Let the solution rest for 15 to 30 minutes at room temperature for complete hydration.
• Stir again before use to ensure homogeneity.

Incorporation into the wine or must

• Slowly and evenly pour the solution into the moving wine or must (pumping over or active stirring).
• Ensure proper homogenization to avoid any local overconcentration.

Immediate use

Use the solution within 3 hours to avoid any risk of contamination.
