    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 However in previous (unpublished) berry drying experiments, as wel...
