Using thiols to make red wines more drinkableRed grape varieties can release thiols, as evidenced by various studies. Their extraction results in wines with fresher, fruitier profiles. Many of us associate volatile thiols with sauvignon blanc, manseng, riesling or colombard. Fewer of us associate them with red wine. Yet thiol precursors are much more frequent in red varietals than could be expected. […]

The use of direct inoculation yeast is less effective and safe than rehydrated yeastSince the development of active dry yeasts for wine in the 70’s, to get the best of them, the best practice has been to rehydrate them in water at 37 °C for a short time, before inoculation of the juice or must to be fermented. However, there is a new trend for so-called “direct inoculation” […]

Enhancing wine aromatic expression through balanced organic yeast nutritionIn the context of climate change, grape musts exhibit chemical changes with micronutrient imbalances. Managing yeast nutrition become again crucial to address these challenges. As well-known, Yeast Assimilable Nitrogen (YAN) significantly impacts alcoholic fermentation, influencing kinetics and wine quality. But other key parameters are vitamins and minerals, vitamins promote yeast growth and stress resilience, while […]

Wine bacteria biodiversity driving sensory profiles of red and whites winesWine bacteria have a more considerable impact on the wine sensory profile than previously thought. New findings have shown that the genetic diversity within the wine bacteria Oenococcus oeni and Lactiplantibacillus plantarum is very rich, and that it can have implications on how the wine bacteria perform, especially in terms of revelation of aroma compounds and wine […]
