SafŒno™ VR 44 BIO sensory features

SafŒno™ VR 44 BIO is convenient for all types of applications even in difficult wine making conditions. Resistant, robust and with low needs in nitrogen, this strain allows to decrease the use of inputs. It is the reason why it is particularly adapted to the production of organic wines.

Organic base wines and prise de mousse

SafŒno™ VR 44 BIO expresses all features that are suitable for high quality organic base wines intended to produce organic sparkling wines through the classic method, i.e. crispness, freshness and frankness. It is also particularly adapted to secondary fermentation (in bottle under the classic method particularly or in tank).

Organic white wines

Ideal for fermentations under controlled temperatures (on Chardonnay, Sémillon, Trebbiano, Malvasia, Pinot Griggio…).

Red wines

Given its fermentations characteristics, SafŒno™ VR 44 BIO allows the production of prestigious organic red wines fine, neat and with terroir characters (Cabernet Sauvignon, Merlot, Carmenère, Barbera, Sangiovese, Teroldego…).


SafŒno™ VR 44 was selected for its excellent fermentation characteristics and its suitability for sparkling wine making conditions (Fermentis® selection).


  • Gently pour the desired quantity of yeast in 10 times its weight of tap water at 30-35°C in a wide vessel. Pay attention to cover all the water surface area by creating a thin layer of yeast.
  • Leave to rest for 20 minutes.
  • Gently stir to complete yeast rehydration while avoiding the formation of lumps prior acclimatization.
  • Double progressively the volume of the yeast suspension by adding must from the tank while stirring the mix so that the temperature of the yeast starter decreases and yeast activation starts.
  • Leave to rest for 10 minutes.
  • Homogenize and incorporate the yeast starter in the fermentation tank during 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 10°C (during 2 years).
Fermentis® guarantees the product complies with the International Oenological Codex until its Best Before End Date in the storage conditions mentioned above. All our products are also fully authorized per TTB 27 CFR 24.246 prior to and during fermentation.

This Fermentis® yeast is developed under a specific organic 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.

The data contained in this technical sheet are the exact transcription of our knowledge of the product at the mentioned date. They are the exclusive property of Fermentis-Division of S.I.Lesaffre. It is of the user responsibility to make sure that the usage of this particular product complies with the legislation.
