Proceedings of the XXIst Entretiens Scientifiques Lallemand held in Geisenheim Institute in Germany focused on cool-climate varietals and to understand how wine fermentation impacts their sensory properties.  The meeting also celebrates the 115^th anniversary of the Geisenheim Research Centre with a presentation by Prof Manfred Grossmann. Topics presented included Margaret River cool-climate Chardonnay, yeast and its role terroir expression in Germany and France, and how MLF impacts cool-climate varietals. CahierGeisenheimComplet

Proceedings of the XXth Entretiens Scientifiques Lallemand held in Horsens, Denmark discusses how Sulphur compounds impact wine aromas – positively and negatively.  Topics presented included prevalence of wine faults from a blind tasting perspective (International Wine Challenge held annually in London), genetics of Sulphur-containing compounds in Saccharomyces and production by O. oeni during MLF.

Wine yeasts are able to produce volatile aroma compounds from precursors found in the grape musts. Despite this ability, the wine yeast needs an adapted nutrition management (type of nutrient and timing of addition) that will maximize this secondary metabolism. Work done in collaboration with INRA (Montpellier, France) has shown that the type of nutrient, and the timing of addition during alcoholic fermentation has an important impact on the production of fermentative aroma compounds. Stimula Chardonnay™ has been shown to maximize specific aroma compounds in Chardonnay wines UI Stimula Chardonnay 2019 ENG USA  

Stimula Chardonnay^TM

Stimula^TM is a new range of 100% yeast autolysate formulated to supply the optimal levels of amino acids, sterols, vitamins and minerals known to optimize the aromatic metabolism of the yeast.  Stimula Chardonnay^TM is particular rich in biotin, B6 vitamins, magnesium and zinc which optimize the volatile ester biosynthesis by the yeast.  Use Stimula Chardonnay^TM at 40 g/hl at the first ¹/₃ into the alcoholic fermentation to enhance the biosynthesis of aroma compounds and support the bioconversion of precursors to volatile esters until the end of the fermentation.   The addition of this new product makes a significant impact on the flavour profile of the wine.  Keep on reading our Nutrient and Protector Under Investigation edition no. 2 for more details.
