ESL 2009: Sensory of cool-climate varietals

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

ESL 2008: Production and sensory impact of Sulphur compounds

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.

Optimal wine yeast nutrition with Stimula Chardonnay™ for maximum aromatic expression in Chardonnay wines

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

Wine Expert #8 – the many roles of Nitrogen during alcoholic fermentation

Wine yeast requires certain essential elements to transform must into wine: sugars, vitamins and minerals, some oxygen, and also very importantly, a sufficient concentration of Yeast Asssimilable Nitrogen. This type of nitrogen (YAN) is composed of amino acids, some small peptides and ammonium that can be used by yeast cells to not only complete fermentation, but also to fully develop the sensory profile of the wine. Many wine musts are deficient in nitrogen and the type of nutrient used and the timing of additi on is crucial in the development of AF. WE#8 ENG
