Blend of inactivated yeasts naturally rich in sterols, fatty acids, vitamins, and minerals, specifically designed for yeast rehydration.

Sterols and unsaturated fatty acids are essential for maintaining the structural integrity of yeast cell membranes. Under certain enological conditions (such as anaerobic environments or low turbidity) yeasts may become deficient in these compounds. This deficiency increases their sensitivity to challenging fermentation conditions (e.g., osmotic pressure, high alcohol, extreme temperatures, or inhibitory substances).

When under stress, yeasts tend to produce more undesirable compounds (volatile acidity, sulfur compounds, medium-chain fatty acids that can inhibit malolactic fermentation) and fewer desirable ones, particularly aromatic compounds. These conditions also heighten the risk of sluggish or stuck fermentations and create an environment favorable to spoilage microorganisms like Brettanomyces.

Œnostim® supports a healthy, complete fermentation and reduces the risk of contamination by helping yeast remain strong and efficient from the start.

This product is allowed for a use in Organic and NOP according to the current regulations.
