    Organic farming may be one solution to reduce the quantities of pesticides used in viticulture. Various innovative organic practices are required because Protected Designation of Origin (PDO) vineyards are planted in very different soil and climate conditions. During the transition to Innovative Organic Viticulture (IOV) i.e. drastic reduction of ...

    Global warming is causing early harvests because of the fast grape total soluble solids accumulation. This results in a decoupling of phenolic and technological ripening, negatively affecting wine quality. In this trial, carried out in cv. Tempranillo under the temperature-warm and semi-arid conditions of eastern Spain, we evaluated the effects on...
