    Several previous open-field experiments have shown that foliar applications with guaiacol solutions can modify wine volatile composition. After such treatment, guaiacol glycoconjugates were detected in fruits, leaves and shoots of Monastrell variety, suggesting that aglycone compounds could be released during wine processing with some changes on t...

    In contrast to malic acid, few studies relate to the metabolism of tartaric acid (TA) under abiotic stress in ripening berries. TA biosynthesis is well known with its metabolism believed to be limited from berry set until véraison and therefore not impacted by ripening conditions. However in previous (unpublished) berry drying experiments, as wel...

    Production of high quality grapes requires balanced vines, assessed through leaf to fruit ratio or Ravaz Index (RI). In some areas with high yield potential, canopy management is used in vineyards to increase yields to profit from this potential. One way is to increase number of shoots per m of canopy. In vertically shoot positioned trellising sys...

    Autochthonous varieties, called ‘criollas’, are highly cultivated in South America. For instance, in Peru or Chile they are used for making Pisco. In Argentina, they represent 33% of the grapevine cultivated area. Surprisingly, research to characterize their attributes for winemaking has been scarce. In this study, we aimed to study agronomica...
