Diluting Powder Tannins 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 conversion table for trials with the decision-support kit —view the conversion table).

Preparation of the Solution

• Prepare hot water equal to 10 to 20 times the weight of the tannins, then gradually add the powder while stirring.

Dilute in hot water while stirring.

• Keep stirring to thoroughly disperse the tannins and obtain a uniform solution without lumps.

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 Wine or Must

• Pour the solution slowly and evenly into the wine or must while it is in motion (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.
