SafŒno™ BC S103 was selected for its excellent fermentation characteristics and its great resistance to extreme winemaking conditions.
This is the workhorse of the Fermentis range, THE yeast we advise for all extreme fermentation conditions (low nitrogen needs high alcohol tolerance…) In short, a yeast we use for safety and in that case (matrix thiols), it is quite neutral in aromatic terms. But if we put it in good conditions (matrixes Esters and Esters/Thiols), we showed a very high production of isoamyl acetate (amylic notes) and of phenylethanol (floral) as well as a rather high thiol release and low ethyl esters production. And this was strictly correlated with fresh, floral and amylic notes. It was a very nice confirmation of the feedback we had from our most staunch customers.
KEY-POINTS
→ Excellent settling strength
→ Wide fermentation temperature spectrum: 10-35 °C
→ Excellent fructose assimilation
→ Very good alcohol tolerance: up to 18% vol./vol.
→ Low nitrogen requirements
SafOeno™ BC S103 is the strain you need…
- For foaming
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.
- To secure 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.
