THE CHOICE FOR EXTREME CONDITIONS
SafŒno™ BC S103 was selected for its excellent fermentation characteristics and its great resistance to extreme winemaking conditions.
Ingredients: yeast (Saccharomyces cerevisiae*), Emulsifier: E491 (sorbitan monostearate)
SafŒno™ BC S103 sensory features
With its technical characteristics, SafŒno™ BC S103 can be used in secondary fermentation whether in bottle under the classic method or in tank (in this last case, it will be preferred to SafŒno™ VR 44).
To respect varietal typicality
SafŒno™ BC S103 makes varietal characteristics more intense and plays a role in producing fine wines typical of their terroir. It is particularly recommended for fresh and neat Chardonnay.
As a curative
Thanks to its resistance to alcohol (18%) and to SO2, SafŒno™ BC S103 is particularly adapted to restart fermentations (high alcohol strength and high SO2 content). Refer to the Fermentis® protocol to restart a stuck fermentation.
Securing fermentations in difficult conditions
SafŒno™ BC S103 adapts to all kinds of musts such as those with a potential high degree, highly clarified ones or musts containing high SO2 levels.
Still White & Red wines: 10 to 20 g/hl
Barrel fermentation: divide the inoculation rate by 2 to allow a regular fermentation without generating a too important temperature increase.
Fermentation restart: 30 to 40 g/hl
Prise de mousse: 15 to 40 g/hl

- Lesaffre know-how and continuous yeast production process improvement lead to obtain an exceptional quality of dry yeasts able to resist to a very wide range of use, cold or no rehydration included, without affecting their viability, kinetic and/or analytical profile.Winemakers can choose usage conditions that fit the best their needs, i.e.:
- Direct inoculation: Pour the yeast on the surface of at least 10 times their weight of must (possibly directly on the top of the tank or during tank filling after settling for whites and rosés). Gently stir to avoid or break clumps. Immediately transfer into the tank via a pumping over with aeration (or homogenize tank volume).
- With prior rehydration: Pour the yeast on the surface of 10 times their weight of tap water at room temperature. Gently stir to avoid or break clumps. Wait for 20 minutes and transfer into the tank via a pumping over with aeration.

The high rate of dry matter of our yeasts assures an optimum storage in its original packaging at a temperature not higher than 20°C (during 3 years) and 10°C for an extended storage (4 years). Fermentis guarantees the product complies with the International Oenological Codex until its Best Before End Date in the storage conditions mentioned above.
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.
Note that you could find a different yeast classification for this product on our sachets and on older versions of our communication tools.
Indeed, this product was previously classified as Saccharomyces bayanus, but as the taxonomic classification of yeasts is a highly evolutive concept, the most recent edition of ‘The Yeast, a taxonomic study’ made us revise our classification to be aligned with the scientific community.
For sustainable reasons, we made the choice to use our remaining stock of printed sachets before we re-print new ones.
In the meantime, don’t worry if you have already fermented your beverage with this yeast strain, yeast taxonomy classification has no impact on the product characteristics.
