Oeno 1

Œno 1® is an Œnococcus Œni strain selected for its resistance against difficult conditions. Able to be used in direct inoculation with a short rehydration step, Œno 1® is particularly well suited for co-inoculation.

Features and Benefits

Formulation: Freeze-dried bacteria – Œnococcus Œni.

Enological benefits: Co-inoculation with Œno 1® saves time by leading to a quick start and completion of the malolactic fermentation, which also saves money and time in heating and labour.

Œno 1® prevents spoilage: produces low volatile acidity, no biogenic amines, and prevents development of Brettanomyces and other undesirable microorganisms. It can also be used in sequential inoculation, after the alcoholic fermentation is finished.

Product Applications

Before inoculation: Let the packet rest at room temperature: 2 hours if stored at negative temperatures (freezer) – 15 minutes if stored at positive temperatures (fridge). Rehydrate Œno 1® bacteria in 20 times its weight in mineral water (no chlorides or sulphur) at room temperature and mix well. Wait 15 minutes and add the malolactic yeast in liquid phase (en rouge traditionnel: under the cap). Homogenize with a pumpover in an oxygen-free atmosphere. It is possible to pour the bacteria directly into the tank without any rehydration beforehand: sprinkle and homogenize without oxygen. Do not carry out any acidification or de-acidification after the addition of the bacteria. For further information, please consult the ‘Good practice for the Inoculation of Lactic Bacteria’ document (available online). Dosage: 1 g/hL.
