Features and Benefits

Formulation: Inactivated yeasts naturally rich in sterols, fatty acids, vitamins, and minerals for the rehydration of ADY.

Enological benefits:

Sterols and unsaturated fatty acids play an important role in maintaining the functional and structural integrity of cell walls. Under certain enological conditions (anaerobic, low turbidities), yeasts are often deficient in these compounds, making them more vulnerable to difficult conditions (osmotic pressure, high ABV, extreme temperatures, inhibitory compounds, etc.).

When under stress, yeasts produce more undesirable compounds (volatile acidity, sulfurous compounds, medium chain fatty acids that inhibit malolactic bacteria) and fewer desirable compounds (especially aromas). Furthermore, the risk of a sluggish and/or stuck fermentation is increased. These conditions favour the development of spoilage microorganisms, such as Brettanomyces.

Œnostim® reduces the risk of contamination by ensuring a quick and complete end to the fermentation.

Product Applications

Dissolve Œnostim® (30 g/L) progressively in 20 times its weight in warm water (37°C), while continuously stirring to avoid the formation of lumps. Then, add the selected yeasts (20 g/hL) and follow the instructions in the ADY rehydration protocol. Finally, incorporate the yeast starter with Œnostim® into the tank with pumping over and homogenize well.

Dosage:

  • 30 g/hL (calculated on the total volume of the tank to be inoculated).

*The quantity of Œnostim® to be added is calculated based on the volume to be fermented.
