Wine Bacteria Product Manager in Lallemand Company, Lallemand Oenology Division


Microbiologist specialized in food industries, I am involved in the world of microorganisms applied to fermented beverages and mainly in oenology and wines. From the selection of yeasts, to the development and marketing of biotechnology and oenological products, I am currently a product manager for wine bacteria in the Lallemand oenology division, the malolactic fermentation is a very qualitative step in the process of vinification, at least as much as the alcoholic fermentation, but is still very few invested. The selected bacteria offer new opportunities for winemaking process , for wine quality meeting the wineakers’s expectations and needs. We try to show these benefits and make the use of selected bacteria more recognized.

GLUTASTAR™ - The king of natural antioxidants
Publiée le 13/06/2019 16:26
Innovation Sustainable development Stabilisation & Bottling
Protection of rosé and white musts against oxidation at the earliest stage of the winemaking process is key to prevent browing and loss of aromas in wine. The addition of inactivated dry yeasts (IDY) containing glutathione is now well known from the winemakers as a tool to limit oxidation phenomena in musts and wines. GLUTASTAR™ is a new specific inactivated yeast with guaranteed glutathione level offering more benefits to the wine than protection against oxidation only.
