Our protocol to restart stuck alcoholic fermentation

Who said restarting a stuck alcoholic fermentation was a long process?
We have developed an easy and short protocol to restart stuck alcoholic fermentation (AF) with the specific selected yeast UVAFERM 43 RESTART™.

Key steps in the protocol include:

1. Stuck wine preparation:

  • Adjust SO₂ levels depending on wine and analysis.
  • Detoxify the wine by adding RESKUE™ cell walls.
  • Rack-off.

2. "Pied-de-cuve" preparation:

  • Prepare a dedicated tank for the "pied-de-cuve" with part of the stuck wine, water and sugar.
  • Yeast preparation: rehydrate UVAFERM 43 RESTART™ yeast, which is pre-acclimated to stress conditions, to ensure a robust fermentation restart.
  • Nutrient addition: incorporate FERMAID O™ to provide essential nutrients and support yeast growth.

3. "Pied-de-cuve" incorporation:

  • When ready, add the "pied-de-cuve" to the full tank of stuck wine.
  • Nutrient addition: add FERMAID O™.
