Oenostim® Direct
Oenostim® Direct is used during yeast rehydration, a key step that determines the quality of alcoholic fermentation. By maximising the yeast’s resistance to harsh environmental conditions (alcohol, anaerobic conditions, acidity, nitrogen deficiency, etc.), it helps to ensure the quality of fermentation.
The enriched formula of Oenostim® Direct improves efficiency during rehydration. After a short acclimatisation phase in water at room temperature, the starter culture can be added directly without the need for a double batch with must, without compromising fermentation quality.

Features and Benefits
- Formulation: Formulation based on yeast autolysates and inactivated yeasts, specifically selected for their high content of ergosterols and unsaturated fatty acids, for the rehydration of active dry yeasts.
- Enological benefits:
- Yeast rehydration is a key step that directly determines the quality of alcoholic fermentation.
- By maximising yeast resistance to challenging environmental conditions such as alcohol, anaerobiosis, acidity and nitrogen deficiencies, it helps to ensure a reliable and optimised fermentation process.
- ŒnoStim® Direct provides a high concentration of ergosterols and unsaturated fatty acids, enhancing yeast resistance while improving intra- and extracellular exchanges.
- Its enriched formulation makes it possible to bypass conventional rehydration protocols and gain in efficiency.
- ŒnoStim® Direct saves time, reduces the risk of contamination and ensures optimal fermentation quality.
- Vegan friendly.
- Usable in organic production in Europe.
Product Applications
Gradually sprinkle ŒnoStim® Direct (30 g/hL) into 20 times its weight of water at room temperature and mix thoroughly to avoid lump formation.
Add the selected yeasts (20 g/hL) and allow to swell for 20 minutes. Then incorporate the yeast starter into the tank using a pump-over to ensure proper homogenisation.
Recommended dosage:
- 30 g/hL, calculated based on the total volume of the tank to be inoculated.
The quantity of ŒnoStim® Direct to be added is calculated according to the volume of the tank to be fermented.
