Biodiversity meets Terrior – 2016 Proceedings of the Entretiens Scientifiques LallemandProceedings of the XXVIth Entretiens Scientifiques Lallemand held in Osoyoos, Canada focused on understanding that microbiological diversity is essential for controlling the production of quality wine. Topics presented included the diversity of microbial populations in the vineyard and in winery fermentations. ESL 2016 Canada – ENG

The many roles of nitrogen in alcoholic fermentationWine 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, […]

A new concept of selected Lactobacillus plantarum for high pH winesThe tendency to harvest higher maturity grapes, resulting in higher pH and alcohol wines, seems more favorable to the development of indigenous bacteria. To limit the development of unknown indigenous flora, which can lead to the production of undesirable sensory deviations, co-inoculation is an interesting winemaking option and using selected Lb. plantarum in the freeze-dried […]

Wine Expert #7 – H2S PRODUCTION BY WINE YEAST DURING ALCOHOLIC FERMENTATIONHydrogen sulphide (rotten egg) aroma is a serious fault in wine and will result in quality loss in the final product. Its production is mainly found during alcoholic fermentation. H2S production by wine yeast varies based on the yeast used as well as on the environmental factors, especially the assimilable nitrogen concentration and micronutriens present. […]
