Location effects on ripening and grape phenolic composition of eight ‘Carignan’ vineyards from Maule Valley (Chile)
ABSTRACT Among the forgotten varieties within the Chilean wine industry, ‘Carignan’ grapevines (Vitis vinifera L.) in the Maule Valley, Chile, have been rediscovered by viticulturist and winemakers, producing very interesting wines and well recognized worldwide. Phenolic compound...

ABSTRACT Among the forgotten varieties within the Chilean wine industry, ‘Carignan’ grapevines (Vitis vinifera L.) in the Maule Valley, Chile, have been rediscovered by viticulturist and winemakers, producing very interesting wines and well recognized worldwide. Phenolic compounds are secondary metabolites, and there has been much interest in potential health benefits of polyphenols as antioxidants. The aim of this work was to study grape phenolic composition from ‘Carignan’ vineyards growing in eight different sites of the Maule Valley during the 2016 vintage. Phenolic compounds were analyzed by HPLC-DAD.
