Features and Benefits

Formulation: Specific preparation of yeast autolyses.

Enological benefits:

  • Natur’Soft® contains autolysed yeast that can combine with anthocyanins, helping to stabilise the colour of red wines.
  • These compounds also interact with tannins, giving roundness and volume on the palate while attenuating green notes.
  • The dual effects of Natur’Soft® can significantly improve the organoleptic properties of red wines.

Product Applications

Add during alcoholic fermentation (EU regulation: only allowed on grapes and fermenting must). Dissolve Natur’Soft® in 5 times its weight in must. Incorporate at the beginning of alcoholic fermentation (AF) and homogenize with a pump over.

Dosage: 30 g/hL
