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...

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.

Wine buyers, consumers and importers are increasingly concerned with the biogenic amines level in wine.
Selected wine bacteria, as well as Bactiless™ are the most efficient and natural solutions to prevent the production of biogenic amines.

In wines, unexpected aromatic treasures can be hidden, which run the risk of not being properly valued. To reveal the aromatic potential of a wine and highlight the grape varietal characteristics, the use of an ad hoc enzyme can be an effective and simple solution.
Using LALLZYME BETA™ helps you win the treasure hunt for aromas in your wine!

How to manage the oxidative risk all along the winemaking 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...

Studies of microbiological impact on aroma profile in wine have recently shown that Lactic Acid Bacteria (LAB) can have just as profound a sensory impact as yeast (Silvano, 2019), yet little research has focused on end-user perception of these differences, in white and red wines.

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.
