Note that you could find a different yeast classification for this product on sachets and on older versions of Fermentis 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 Fermentis revise its classification to be aligned with the scientific community.
For sustainable reasons, Fermentis made the choice to use the remaining stock of printed sachets before re-printing 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.
