Genesis Lift

 

Oenofrance yeast product suited for white, rose and red wines.

Oenofrance worked over 10 years with professeur Michel Feuillat and his team from Université Jules Guyot (Dijon) over the yeast products and their multiple potential applications in winemaking. Our knowledge of these yeast products grew as years went by. The fruit of this knowledge is the Genesis line of products which is centered around the various identified and controlled properties of those yeast products.
Genesis Lift is based on a selection of yeast hulls from a yeast strain with particularly abundant mannoproteins from their walls and undergoing innovative treatments (Œnolysat process). Used in wines, it favors the end of fermentation by removing the toxins. Mannoproteins released during fermentation or aging have a positive impact on mouthfell.



  

Composition :

Preparation from yeast hulls
 

Properties :

 
• By adsorption on the yeast hulls, Genesis Lift removes the toxins and the pesticides residues which will be separated from the wine during a racking or a filtration.
• The yeast walls are composed of polysaccharides (glucanes) and glycoproteins (mannoproteins). Genesis Lift is able to release mannoproteins during its contact with the wine. Those mannoproteins can improve the volume of the wine or, by a combination with tannins, can reduce the feeling of astringency and the loss of color in red wines.
Augustin (1986) has shown that an addition of yeast hulls improves the color intensity and the hue of red wines. With yeast hulls, tannins are less reactive towards proteic fractions of gelatin because glycoproteins combine with tannins and reduce their reactivity towards proteins, and therefore their astringency.
In fact, the wines are less astringent (lower BSA index, Bovine Serum Albumin), that’s what we show during an experiment on a press wine from Medoc (France, vintage 2003). After three months, the wine added with 20g/100 liters of Genesis Lift has a BSA index lower than the control : it is less astringent. During tasting, this diminution enhances the quality of the wine.
