Outstanding Colour Stability
Grape Skin Tannin contains a high concentration of complex wine pigments that are responsible for stabilizing the colour of red wine during ageing. Unlike simple anthocyanins these complex pigments:

• Maintain their colour at low pH
• Are resistant to sulphur dioxide bleaching
• Are stable to oxidation

Grape skin tannin can be used to add value, improve quality, and enhance wine structure and mouth feel.
