Tannic Acid is a natural water soluble plant-derived tannin — food grade and ideal for use in winemaking and home brewing. It improves mouthfeel, supports clarity, and helps your wine age more smoothly.Tannic acid powder adds structure, body, and balance to homemade wine. If your wine tastes flat, thin, or lacks that satisfying dryness, tannin is usually the missing piece.

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 during fermentation or finishing. Start with a small dose and adjust to taste.

Bonus use — rust conversion: Tannic acid is also widely used in metal treatment. When applied to rusted surfaces, it reacts with iron oxide to convert and stabilise rust, preparing the surface for painting or sealing. This product is supplied for winemaking purposes but the same chemistry applies.
