YEAST RANGE

Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom that play an essential role in winemaking to control and regulate the alcoholic fermentation. The most commonly used strains are Saccharomyces cerevisiae, although in recent years new species have been developed (e.g., Torulaspora, Metschnikowia, etc.), which allow the natural organoleptic characteristics of the grape variety to be expressed more fully. Our active dry yeasts are packaged in 100 gram, 500 gram and 10 kg vacuum packages.

The choice of each of our yeast varieties has been carefully elaborated and considered according to many criteria such as:

Our yeasts are natural and are selected and characterized in collaboration with various national and international research institutes, universities, and experimental stations in order to better target our offer and thus meet market expectations.
Our range of yeasts allows oenologists throughout the world to find the yeast best suited to their needs, requirements, and specificities. They are used by winemakers all over the world and for all types of wines, including organic wines.

None of wine yeasts have not undergone any genetic modification and comply with the Oenological Codex.
