¹Analysis done according to our HACCP study

Lesaffre know-how and continuous yeast production process improvement generates an exceptional quality of dry yeasts able to resist to a very wide range of uses, including by-passing acclimatization, cold or no rehydration conditions, without affecting their viability, kinetic and/or analytical profile. Winemakers can choose to use our E2U^TM yeast with the process that fits best their need:

• Direct inoculation: Inoculate the desired quantity of yeast directly into the must in the fermentation tank, taking care to homogenize the entire volume. In whites or roses, ideally directly sprinkle the yeast into the fermentation tank after the beginning of the transfer from the settling tank and keep transferring to ensure a good homogenization. Alternatively pour the desired yeast quantity on the surface of at least 10 times its weight of must. Gently stir to avoid clumps. Immediately transfer into the tank and homogenize the entire volume.
• With prior rehydration and potential acclimatization: Gently pour the desired quantity of yeast in 10 times its weight of tap water from 15-37°C (59-98.6°F). Gently stir to complete yeast rehydration and avoid the formation of clumps. Leave it to rest for 20 minutes and incorporate the yeast starter in the fermentation tank with homogenization. Following the rehydration, it is possible to continue with an acclimatization by incorporating to the yeast starter ½ of a volume of must and leave it to rest for 10 minutes. Repeat the operation until the temperature difference between the fermentation tank and the yeast starter culture is less than 10°C (50°F).

Packaging

Guarantee

The product must be stored/transported in dry conditions and protected from direct sunlight. For less than 6 months, the product can be stored/transported at ambient temperature below 25°C (77°F) without affecting its performances. Peaks up to 40°C (104°F) are allowed for a limited period of time (less than 5 days). Fermentis recommends a long-term storage at a controlled temperature (below 15°C/59°F), once the product arrives to the final destination.

Each Fermentis yeast is developed under a specific production scheme and benefits from the know-how of the Lesaffre group, world leader in yeast manufacturing. This guarantees the highest microbiological purity and maximum fermentation activity.
