What metabolomics teaches us about wine shelf life

Abstract

The metabolomics era started about 22 years ago, and wine was one of the first foodstuff subjects of analysis and investigation by this technique. Wine, which is most likely the richest food in terms of number of metabolites, was an excellent chemical model solution for chemists to explore the potentialities of this new technique, which enable untargeted study. Since then, metabolomics techniques were applied in several oenological studies shedding light on numerous questions from vine to glass.
In fact, metabolomics techniques helped us to gain knowledge on the chemical modifications taking place during the wine aging and shelf life, which has a paramount importance since wine is one of the few foods that aging may improve its sensorial character and economical value. Recently, the combination of well-designed experiments, high-resolution mass spectrometers and modern informatic tools opened new roads for better understating how primary and secondary metabolites are modified during aging, and we learned new reactions taking place or followed in detailed reactions which were not very clear. This talk will provide a snapshot of recent publications regarding the behaviour of wine’s metabolome during shelf life.

Soil survey and chemical parameters evaluation in viticultural zoning

The most recent methodological developments in soil survey and land evaluation, that can be taken as reference in the viticultural field, go over usage of the GIS and database. These informatic tools, which begin to be widely utilised, consent to realise evaluations at different geographic scale and with different data quality and quantity in entrance.

Diffuse light due to wildfire smoke enhances gas exchange of shaded leaves

The risk of wildfires is increasing as the frequency and severity of drought and heat waves continue to rise. Wildfires are associated with the combustion of plant materials and emit smoke. In the atmosphere, smoke may spread readily across large areas. Smoke is composed of solid and liquid phase particulates and gases and has been identified as a causal agent of “smoke taint” in wine. On a smoky day, the intensity of direct light decreases because these particulates scatter sunlight. Even though this effect is frequently assumed to decrease plant photosynthesis, this assumption ignores the potential changes in diffuse light and may be based on scant evidence.

Vitamins in musts : an unexplored field

Vitamins are major compounds, involved in several prime yeast metabolic pathways. Yet, their significance in oenology has remained mostly unexplored for several decades and our current knowledge on the matter still remaining obscure to this day. While the vitaminic contents of grape musts have been approached in these ancient investigation

Methodology of climate modelling using land surface temperature downscaling: case study case of Gironde (France)

Aim: Climate modelling in viticulture introduced new challenges such as high spatio-temporal monitoring and the use of dependable time series and robustness modelling methods. Land surface temperature (LST) is widely used and particularly MODIS thermal satellite images due to their high temporal resolution (four images per day).

La haie bocagère comme critère de zonage à l’échelle parcellaire

In the French AOCs, the production area of ​​the raw material can be subject to plot delimitation based on criteria of physical environment and use. On the other hand, many environmental zonings are developing and the AOCs are called upon include provisions relating to these concerns. Hedges, through their effects on local changes in the regional climate and on functional biodiversity, can impact the functioning of vines and orchards. It is for this reason that their consideration as a delimitation criterion is envisaged.
