Do high temperature extremes impact berry tannin composition?
Flavonoids, including flavonols, anthocyanins, and tannins, are important contributors to grape and wine quality, and their biosynthesis is strongly influenced by bunch microclimate.
Molecular characterization of wines nucleophilic potential by ultra-performance liquid chromatography high resolution mass spectrometry
The knowledge about the molecular fraction associated to white wines oxidative stability is still poorly understood.
A new graphical interface as a tool to integrate data from GC-MS and UPLC-MS-QTOF: new compounds related with port wine aging
Port wine value is related to its molecular profile resulting from the changes occurring during the ageing period. It is of empirical knowledge that the style is greatly affected by the oxidation regimens, i.e. bottle versus barrel storage
Q-NMR measurements: quantitative analysis of wine composition applied to Bordeaux red wines authenticity control
Traceability of wine is today a consumer demand and a scientific challenge. The methods of analysis must be able to control three fundamental parameters: the geographical origin, the grape varieties, and the vintage.
