Tannic Acid Powder is a food-grade, plant-derived tannin designed to improve the structure, clarity, and ageing potential of wine and homebrew. Ideal for both beginners and experienced winemakers, it helps transform flat or thin wines into balanced, full-bodied results.

What tannic acid does in winemaking:

• Adds grip, body, and a subtle dryness to red and white wines
• Reduces flat or thin flavours
• Improves clarity and stability
• Supports smooth ageing

How to Use

Add tannic acid during fermentation or finishing stages. Start with a small dose and adjust gradually to achieve the desired taste and balance.

Additional Use: Rust Conversion

Tannic acid also reacts with iron oxide to convert rust into a stable compound, making it useful for preparing metal surfaces before painting or sealing.
