    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...

    There is some evidence that sugar accumulation is retarded in minimally pruned vines. This may be caused by an excessive yield (i.e. low leaf to fruit ratio) that could affect grape enological quality. Our goal was to evaluate the effect of crop load on grape and wine composition for Cabernet Sauvignon under minimal pruning during two seasons (201...
