Managing 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, more specifically on how the specific yeast derivative, Glutastar™ can support the process of managing oxidation in white and rosé wines in a strategy to reduce chemical intrant such as SO2.

Managing 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 supervision of SALMON JM showed the potential of specific inactivated yeasts to consume oxygen and protect wine from oxidation. One of the tested SIYs particularly stood out for its outstanding ability to scavenge oxygen. And it is now made available to #winemakers: PURE-LEES LONGEVITY.   Winery scale trials demonstrated that using PURE-LEES LONGEVITY at the most sensitive post-fermentation stages enables to protect the wine against oxidation while reducing SO₂ additions.   🍷 PURE-LEES LONGEVITY is an essential tool to control wine oxidation post-fermentation and can be part of an overall #bioprotection strategy to preserve wine #aromas and color, and confer a longer shelf life and a better market value to your wine.   Discover all the results in our Winemaking Update Part II 👉 WUP - Oxidation - Pure-Lees ENG

NoBrett 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 - JMH ENG
