AEB Fermotan Liquid | Fermenation Tannin | 25 kg

• Designed for use during fermentation to stabilize color and improve phenolic integration
• Mixes much easier than powdered tannins thanks to its liquid formulation
• Composed of ellagic tannins (oak) and condensed tannins (exotic woods)
• Protects wine from oxidation by acting as a sacrificial tannin and antioxidant
• Promotes anthocyanin-tannin binding, improving long-term color and mouthfeel stability
• Ideal for red wines needing structure, color retention, and oxidative protection from the start

Fermotan Liquid is a balanced blend of ellagic, proanthocyanidinic, and gallic tannins designed to strengthen color, stabilize phenolic compounds, and shape the sensory profile of wines. Its liquid formulation makes it easy to dose and ensures rapid integration without the need for prior solubilization. Used during red wine fermentation, Fermotan Liquid enhances structure, preserves varietal character, and supports long-term aging potential. The result is a wine with deeper color, lifted aromatics, and a rounder, more polished mouthfeel compared to tannins from other sources.

From the onset of fermentation, anthocyanins are extracted faster than tannins. In order not to extract these color compounds in vain, it is imperative to protect them from the oxygen and steer them towards stable polymerization forms, such as those with proanthocyanidins. The synergy among the three classes of tannins (ellagic, proanthocyanidinic and gallic), exerts a triple protective action towards the anthocyanins.

Protocol
Add directly to the must at the beginning of alcoholic fermentation, ensuring thorough homogenization.
