Made from fresh and seasoned oak, Harvest Tannin is used the same way as powdered fermentation tannins, yet has a much smoother effect. It is easier to measure and disperse than powder, and is competitively priced. Harvest Tannin adds structure, preserves color and covers most vegetative characters.
Tannin content ≈150 g/liter
Added prior to fermentation, these semi-polymerized tannins will bind and help stabilize color and flavor compounds, protect from oxidation while preserving the fruit character through the fermentation process.
