Effects of oak barrel aging monitored by 1H-NMR metabolomics

Abstract

The study of wine evolution during barrel aging is an important aspect of wine quality. Our previous works have shown that wine metabolome monitoring by

1H-NMR approaches allows determining the impact of different winemaking processes including traitements using enzymes or finning agents [1]. In this study, the effects of oak barrel aging were investigated by 1H-NMR metabolomics. Targeted and untargeted 1H-NMR analyses were performed on wines conserved in barrels provided by four different barrel manufacturers. Wine samples were taken after one and twelve months. The collected data were statistically processed by principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA), and partial orthogonal least squares discriminant analysis (OPLS-DA). Cross permutation tests and ANOVA were performed to validate the results and determine the compounds significantly impacted. The results of chemometrics analyses show the relevance of 1H-NMR metabolomics for studying the impact of oak barrel aging. The targeted analysis allowed us to identify the compounds that evolved during barrel aging. The untargeted analysis proved to be particularly interesting for the study of the specific signature of each barrel makers. 1H-NMR metabolomics is a rapid method that could be used as a decision support tool for winemaking.

Grouping Vitis vinifera grapevine varieties based on their aromatic composition

Climate change is likely to impact wine typicity across the globe, raising concerns in wine regions historically renowned for the quality of their terroir1. Amongst several changes in viticultural practices, replacing some of the planting material (i.e. clones, rootstocks and cultivars) is thought to be one of the most promising potential levers to be used for adapting to climate change. But the change of cultivars also involves the issue of protecting the region’s wine typicity. In Bordeaux (France), extensive research has been conducted on identifying meridional varieties that could be good candidates to help guard against the effects of climate change2 while less research has been done concerning their impacts on Bordeaux wine typicity.

Caractérisation et gestion de la maturation par terroir en Champagne

Pour prévoir et gérer chaque année les principales caractéristiques de la maturation en Champagne, le CIVC (Comité Interprofessionnel du Vin de Champagne) a développé un ensemble de moyens de prévision et d’information très performants qui permettent aux différents acteurs de la filière viti-vinicole de prendre en compte ces informations à l’échelle de chaque terroir communal pour la recherche d’une qualité optimale.

New food trend ahead? Highlighting the nutritional benefits of grapevine leaves

The wine industry produces an enormous amount of waste every year. A wider inclusion of disregarded by-products in the human diet or its use as a source of bioactive compounds is a good strategy for reducing waste. It will not only introduce an added value to a waste product but also come upon the European Union and United Nations’ demands towards more sustainable agricultural approaches and circular economy.
