Innovation Stabilisation & Bottling Grapes & wines analysis Sensory analysis Microbiology
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.

Innovation Stabilisation & Bottling Sensory analysis Microbiology
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.

The wine world has changed vastly in the last six months due to COVID-19, and has affected all parts of the distribution network, from producer all the way to consumer, and everything in between.

Lallemand Oenology organized a webinar to try to understand from a market point of view how things are shaping up, how the wine market is affected and what is next. Four experts in the field participated to this exclusive event. Sam Harrop MW and consultant in Spain, Chile, Japan and New Zealand, Ja...

A new spanish study performed in collaboration with technical institutes investigates the effects of co-inoculation ( inoculation of wine bacteria 24 hours after yeast addition)  with two different  wine bacteria Oenococcus oeni  (PN4 and OMEGA under MBR form , from Lallemand oenology)  on the kinetics of malolactic fermentation (MLF), wine chemical composition, and organoleptic characteristics in comparison with spontaneous MLF in Tempranillo grape must from Castilla-La Mancha (Spain).
A new generation of wine yeasts that helps to manage undesirable sulfur compounds in wines

In a collaborative study conducted with the ICV Group, Montpellier Supagro and the INRA Montpellier (through a PhD focusing on the genetic basis of sulfur production by yeast to identify the molecular determinants involved in the yeast’s SO₂ metabolism, carried out in 2011 by Jessica Noble with Bruno Blondin, from the INRA Montpellier as PhD supervisor), Lallemand Oenology identified, through an innovative QTL approach, the molecular basis of SO₂ production in yeast to eventually be able to re...
Copper sulfate use in organic vineyards: Are wine yeast and bacteria affected by this fungicide?

Innovation Grapes & wines analysis Viticulture Sustainable development
In 2017, the organic vineyard areas had tripled in 10 years and approximately 5% of worldwide vineyards are now under organic certifications. The growth is also reflected in consumer consumption of organic wines, not only in Europe but all over the world where in Sweden for example, the growth is 51%, in France 36%, and in Australia, 120%.
The extraordinary & infinite world of non-Saccharomyces yeast

Innovation Sustainable development
Although non-Saccharomyces yeasts have long been considered harmful to alcoholic fermentation, nowadays research associates these strains with a real potential for differentiating wines. Progress in the field of molecular biology has led to the discovery of the roles played by various non-Saccharomyces yeasts. Their impact on the final composition of wine is very interesting, as they are able to enhance the complexity of the aroma profile of wines. Some can enrich the must in metabolites that ha...
The impact of copper in winemaking and how to control it
Publiée le 10/12/2019 14:13
During the 2019 edition of the Sitevi, a conference was organized on the effects of copper in winemaking and how winemakers could monitor, control and minimize them. Marion Bastien, from Lallemand Oenology, was one of the speakers and her speech particularly focused on the impact of copper on yeast and bacteria during the alcoholic and malolactic fermentations.
