Hygiene & disinfection Enological Consulting Microbiology
Managing the risk associated with microbial spoilage is a key point throughout the life of a wine.
SO₂ is the commonly used product to limit microbial contaminants, especially Brettanomyces and undesirable lactic and acetic bacteria, although the market is looking for wines with lower contents. Pure chitosan and chitosan associated with chitin-glucan are biological alternatives of great interest.

Our latest Under Investigation issue focuses on the mode of action and efficiency of these biol...

Enological Consulting Microbiology Stabilisation & Bottling
We have seen in Part I of Managing oxidative risk with biological tools how to fight oxidation in prefermentation stages with specific inactivated yeasts, such as GLUTASTAR™.
But there are also sensitive stages post fermentation, where wine needs to be protected from oxidation. PURE-LEES LONGEVITY™ is an essential tool to reach this goal.

Sensory analysis Vinification process
Grape compounds such as pectin, hemicelluloses, celluloses and glucans can impact the winemaking process, cause product loss and increase costs and time.
Specific enzymes such as pectinases, hemicellulases, cellulases and β-glucanases can help overcome these problems resulting in a smoother and more efficient process.
Glycosidases are specific enzymes able to increase the primary aroma of wine. Typically, oenological enzyme preparations include a mix of several synergic activities in order t...
An original and new specific inactivated yeast to improve the oxidative stability of white and rosé wines
Publiée le 23/09/2020 07:55
Microbiology Stabilisation & Bottling
This paper presents a research work carried out in collaboration with the University of Burgundy, which has highlighted the impact of a new specific inactivated yeast developed for the protection of musts and wines against oxidation.

This results from the application of an optimized production process to a unique strain of Saccharomyces cerevisiae yeast to maximize the biosynthesis and accumulation of intracellular glutathione and other compounds of interest.
