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.

Volatilome in grapevine leaves is defined by the variety and modulated by mycorrhizal symbiosis

Volatile organic compounds (VOCs) constitute a diverse group of secondary metabolites key for the communication of plants with other organisms and for their adaptation to environmental and biotic stresses. The emission of these compounds through leaves is also affected by the interaction of plants with symbiotic microorganisms, arbuscular mycorrhizal fungi (AMF) among them [1]. Our objective was to know the concentration and profile of VOCs emitted by the leaves of two grapevine varieties (Tempranillo, T, and Cabernet Sauvignon, CS, grafted onto R110 rootstocks), inoculated or not with a consortium of five AMF (Rhizophagus irregularis, Funneliformis mosseae, Septoglomus deserticola, Claroideoglomus claroideum and C. etunicatum).

Study of varietal wines from the qualified origin denomination Rioja (Spain): analysis of wine colour, polysaccharides, polyphenols and biogenic amines and amino acides 

The cultivar with a greater oenological potential was ‘Monastel’, which showed overall better values than ‘Tempranillo’ in colour intensity, total polyphenol index, wine colour, total anthocyanins, resveratrol and gallic acid.

A first look at the aromatic profile of “Monferace” wines

Grignolino, is a native Piedmont grape variety which well represents the historical and
enological identity of Monferrato, a territory between Asti and Casale Monferrato, included in the World Heritage List designated by UNESCO (1).

VOLTAMETRIC PROFILING OF RED WINE COMPOSITION DURING MACERATION: A STUDY ON FOUR GRAPE VARIETIES

During red wine vinification, maceration allows the must, and consequently the wine, to be enriched with several compounds that contribute to the creation of the typical organoleptic characteristics of red wines. Among these, extraction of polyphenols (PPs) during maceration is a major process of enological interest.
The purpose of this study was the evaluate the suitability of a rapid analytical approach based in linear sweep voltammetry to monitor PPs extraction during vinification.
