Biogenic Amines in Wine and how to control themBiogenic amines are found in fermented food and beverages, including wine. Of the many biogenic amines, histamine, tyramine and putrescine are the most important in wine. It is the metabolism of amino acids by lactic acid bacteria that produce the biogenic amines found in wine. Red wines tend to have higher biogenic amines content than […]

NON-SACCHAROMYCES: BIODIVERSITY UNDER CONTROLWine Yeast Under Investigation #3 The initial microbial population present in grape must is very diverse. During the early stages of alcoholic fermentation, Saccharomyces cerevisiae is not the dominant specie and other species (non-Saccharomyces) are present. Non-Saccharomyces yeasts are part of the must microflora and represent an important reservoir of the wine sensory potential. While […]

Managing oxidative risk with biological tools – Glutastar™ in Pre-fermentationManaging oxidative risk Throughout winemaking, several steps are known as strategic key points where oxidation mechanisms can occur: transport of grapes, at pressing, stabulation, racking, at the beginning of AF, during cold stabilization, storage and transport. This Winemaking Update will focus on biological tools available to winemakers to control oxidation prior to the onset of alcoholic fermentation, […]

Managing oxidative risk with biological tools Post-fermentation with Pure-Lees™ LongevityManaging Oxidative Risk We have seen in Part I of Managing oxidative risk with biological tools how to fight #oxidation in must with specific inactivated #yeast, such as Glutastar™, during pre-fermentation stages. But there are also sensitive stages post fermentation, where #wine needs to be protected from oxidation. A research conducted by the INRAE, under the […]

Glutastar improves freshness and increases shelflife in your aromatic whites and rose.The GlutaStar Journey Our video retraces the history of our latest glutathione-rich inactivated yeast, Glutastar, developed to protect white and rosés #musts and #wines from oxidation while reducing the use of SO2. The video showcases how this innovative tool was researched and developed in a 5-year fruitful collaboration with the #IUVV in Dijon, France, and notably with Regis Gougeon team and particularly Florian Bahut thesis. You will […]

A NATURAL TOOL TO FIGHT BRETTANOMYCESNoBrett Inside Brettanomyces bruxellensis constitutes a permanent threat to the quality of wines. These wine alteration yeasts can develop in difficult environments and at any time during the life of a wine, but particularly during the aging phase. Different means are currently used to fight against Brettanomyces, with varying degrees of success. However,…… NBI Chitosan […]
