SELECTYS® LA MARQUISE is S. Cerevisiae galactose yeast selected for its great qualities in the production of still wines. It has very good implantation capacity and good fermentation speed, thus ensuring the smooth progress of the AF even when there is heavy contamination (high pH, deficient health conditions, etc.). It is resistant to high alcohol content (15.5%) and to difficult conditions (low temperature, overclarified must, etc.), and can be used to obtain great wines, both red and white.
