Yeast needs nitrogen, among other things, to grow and ensure a smooth and complete alcoholic fermentation (AF).  If the assimilable nitrogen is less than 140 mg/L, the grape must is considered deficient, and in this case wine yeasts need an addition of external nitrogen. Nitrogen for the yeast comes in different forms What is complex […]

Beyond looking at nutrition or completing #fermentation, Lallemand Oenology has developed a range of #nutrients which aim at optimizing the aromatic expression of your #wines, by nourishing the #yeast and stimulating the yeast cell functions involved in aroma metabolism: the #Stimula range. Each of the 4 products already available in the range are based on 4 wine yeast strains optimized with amino acids, vitamins […]

UNDER INVESTIGATION NO4 The use of selected wine yeast in dry form dates to the mid-1960’s (Kraus et al, 1983). Gradually, this practice has been one of the most important innovation in winemaking.  It allowed winemakers reliability and security during alcoholic fermentation (AF), as well as a tremendous choice of different yeasts, without the concern […]

Wine Yeast Rehydration Proper wine yeast  rehydration is necessary because grape must is a very hostile environment with its low acidity, high sugar and osmotic pressure, and nutrients or micronutrients limitations is a big challenge for any yeast to conduct AF. Quality, fault free wine is related to a successful AF, and that comes with taking good care […]
