Tanin VR Skin (500 gr)

Proanthocyanidic tannins extracted from grape skins using LAFFORT’s Instant Dissolving Process (IDP).

Qualified for the elaboration of products for direct human consumption in the field of the regulated use in oenology.
In accordance with the current EU regulation n° 2019/934.

Specificiations and oenological applications

Due to its specific nature (grape skin tannin) TANIN VR SKIN® will allow:

  • Compensation for natural grape tannin deficiency (lack of phenolic maturity or adverse tannin-anthocyanin ratio).
  • Stabilisation of colour due to the formation of tannin-anthocyanin polymeric pigments.
  • Improved fining.
  • Refinement and enhancement of wine structure and palate length.

Physical characteristics

  • Aspect: granulated
  • Solubility in water: complete
  • Colour: brown

Chemical analysis

  • Total phenolics (%) > 65
  • Humidity (%) < 10
  • Ash (%) < 4
  • Insoluble substances (%) < 2
  • Arsenic (ppm) < 3
    Iron (ppm) < 50
  • Lead (ppm) < 2
  • Mercury (ppm) < 1
  • Cadmium (ppm) < 1

Protocol for use


  • Colour stabilisation: 20 - 40 g/hL (200 - 400 ppm)

TANIN VR SKIN® can be sprinkled directly onto must or wine (thanks to the IDP process), during homogenisation or a pump-over.
In the case of colour stabilisation, add TANIN VR SKIN® during a pump-over at the start of fermentation.
