HARVEST PROTECTION WITH SG TANNINS

The earliest moments of harvest are decisive for preserving grape quality. Oxidation, microbial activity and colour loss can all compromise the final wine before fermentation even begins. Enologica Vason's SG (Special Granulation) tannin range is designed to provide immediate protection with one key advantage: exceptional solubility, allowing rapid dispersion and instant action directly in the must and juice.
Thanks to the SG treatment, these tannins dissolve quickly in water, ensuring homogeneous distribution and maximum effectiveness from the moment they are added.

V TAN® UVA SG
Colour Protection from the Start

V TAN® UVA SG combines ellagic, gallic and grape catechin tannins to deliver a synergistic action that protects and stabilises colour during maceration.

Key benefits:

  • Inactivates oxidative enzymes naturally present in grapes or produced by Botrytis cinerea.
  • Promotes stable anthocyanin binding for improved colour retention.
  • Increases resistance to oxidation while enhancing wine structure and body.
  • Recommended from the beginning of maceration and after the first racking.

SAFE TAN® SG
Early Oxidation Control – Must and Juice Protection

SAFE TAN® SG is a carefully selected blend of hydrolysable gallic tannins, developed to protect grapes from oxidation from the moment they arrive at the winery.

Key benefits:

  • Immediate antioxidant protection.
  • High protein reactivity for effective clarification.
  • Enhanced protection of colour and aroma compounds.
  • Excellent support for compromised or Botrytis-affected grapes.

EASYTAN® HARVEST SG
Natural Antioxidant Support Throughout Harvest

Produced from carefully selected woods rich in ellagic tannins, EASYTAN® HARVEST SG provides antioxidant protection while contributing sweetness, volume and greater body to wines.

Key benefits:

  • Protection against oxidation in white, rosé and red winemaking.
  • Improved colour stability in red wines.
  • Clarification and protein stabilisation.
  • Increased palate breadth and balance.
  • Ideal from grape reception and crushing, suitable for Flash Détente processes to protect the must from oxidation and support colour stability.

Harvest Sequence:

- V TAN® UVA SG – Colour extraction and stabilisation.

- SAFE TAN® SG – Oxidation control and protection of aromas and colour.
