Previous results have shown the impact of the pH on the stability of white wine proteins. In a context of global warming that implies increases in ethanol content and pH, we wanted to compare for the

Cu organic acid complexes efficiently bind hydrogen sulfide in wine and therefore prevent its accumulation and subsequent reductive off-flavour [1]. This fraction of Cu can also bind methanethiol, ...

Viticulture and oenology face two major challenges today, climate change and the reduction in the use of inputs. Climate change induces low acidity and microbiologically less stable wines, implying...

The main objective of this work is to study and model the impact of the polyphenolic profile on the stability and quality of wine aroma during oxidative aging. Aromas considered in the study are...

The aim of this study was to evaluate the role of pH on both acetaldehyde chemistry and and wine phenolics evolution over the aging period. In addition, the effect of both an early and late acidifi...

Some red wines develop a “bouquet” during ageing. This complex aroma is linked to quality by wine tasters. The presence of dimethylsulfide (DMS) in those wines is implicated in the expression of “b...

The overall quality of fine wines is linked to the development of "bouquet" during wine bottle ageing. Bordeaux red wine ageing bouquet is defined by the association of several odours including fresh

The quality of bottled white wines is highly influenced by their storage conditions, mainly temperature, and exposure to light and oxygen. The aim of this work was to study the effect of different ...

Prematurely aged red wines are marked by intense prune and fig aromatic nuances that dominate the complex bouquet that can be achieved through bottle aging. This oxidation off-flavor in part is cau...

This research activity focuses on the study of the chemical and biochemical mechanisms underlying the white wines oxidative stability, the development of analytical tools for predicting wines aging...

Aromatic profile of a bottled wine evolves mainly under the influence of oxygen to which it is exposed at bottling and during bottle aging. The closure permeability is therefore an essential choice...
Among red wine ethyl-esters, those from short-chain substituted acids play the role of natural enhancers of fruity notes in red wines. Can we predict the "aromatic potential" of these esters?
