Œnococcus œni strain particularly robust in difficult conditions, combined with the exlcusive production process: PreAc®. Qualified for the elaboration of products for direct human consumption in the field of the regulated use in Œnology. In accordance with the International Œnological Codex. SPECIFICATIONS AND ŒNOLOGICAL APPLICATIONS • Resistance to low pH even in binding conditions.
• Resistance to medium chain fatty acids (C8 and C10). Survival and activity spectrum of the LACTOENOS 350 PreAc® bacteria. LACTOENOS 350 PreAc® pre-acclimatized NB: these parameters have a cumulatively inhibiting effect. Up to 16 From 2.9 Up to 80 Ethanol content (% vol) Temperature From 15°C ≤ 60 mg/L of C8 ≤ 15 mg/L of C10 C8 and C10 Total SO2 (mg/L) LACTOENOS 350 PreAc® is efficient on any wine with high contents of C8 and C10 (white, red and rosé).
LACTOENOS 350 PreAc® is adapted to low pH wines, including whites wines and certain rosé wines.
