MetabolomicsMetaDB a Data Processing Workflow in Untargeted MS-Based Metabolomics Experiments
This dataset reports the UPLC-QTof MS untargeted analysis of Vitis vinifera L. leaves, collected from Italy (Trentino) and Germany (Mecklenburg West-Pomerania), from two fungus-resistant grape varieties (PIWI), Regent and Phoenix. For each variety, 40 leaves were sampled from 10 plants (4 leaves/pla...

MetabolomicsUse of untargeted LC-MS metabolome to discriminate Italian mono-varietal red wines, produced in their different terroirs
The aim of this project was to register in a LC-MS-based untargeted single-batch analysis, the metabolome of 11 single-cultivar, single-vintage Italian red wines (Aglianico, Cannonau, Corvina, Montepulciano, Nebbiolo, Nerello, Primitivo, Raboso, Sagrantino, Sangiovese and Teroldego) from 12 regions ...

MetabolomicsThe influence of storage on the “chemical age” of red wines
Storage conditions and duration have a considerable influence on wine quality. Optimum temperature and humidity conditions may improve wine quality through ageing, while incorrect or excessively long storage leads to negative results. In order to evaluate the global effects of storage on red wine co...

MetabolomicsFlint glass bottles cause white wine aroma identity degradation

Due to marketing recommendations, white wines are often bottled in flint glass to improve aesthetics and showcase wine color. Although this practice is known to cause a wine fault, the influence of light on the fruity and flowery aromatic profile of wine is unknown. The aim of this study was to i...

MetabolomicsLC–MS-Based Metabolomics Discriminates Premium from Standard Chilean cv. Cabernet Sauvignon Wines from Different Valleys

Cabernet Sauvignon grapes in Chile, mainly grown between the 30 °S and 36 °S, account for more than 30% of Chilean wine production, and yield wines with different characteristics which influence their quality. The aim of this study was to apply an LC-MS based metabolomic protocol to investigate t...

MetabolomicsInvestigation of Brazilian grape juice metabolomic profile changes caused by methyl jasmonate pre-harvest treatment

Grape juice is a major source of potential health-promoting bioactive polyphenols, especially for children and those who do not consume wine. Since the subtropical climate may negatively affect the concentrations of grape polyphenols, especially anthocyanins, elicitors such as methyl jasmonate (M...

MetabolomicsTranscriptome and metabolite profiling reveals that prolonged drought modulates the phenylpropanoid and terpenoid pathway in white grapes (Vitis vinifera L.) (Carotenoids; UPLC-DAD assay)

BACKGROUND: Secondary metabolism contributes to the adaptation of a plant to its environment. In wine grapes, fruit secondary metabolism largely determines wine quality. Climate change is predicted to exacerbate drought events in several viticultural areas, potentially affecting ...

MetabolomicsA Metabolome Atlas of Grape Biodiversity
Grapevine (Vitis spp.) is one of the world’s most economically, culturally, and biologically important fruit crops, with remarkable diversity spanning thousands of V. vinifera cultivars together with rootstocks and wild relatives. Yet grapevine biodiversity has never been systematically explored at ...
