The world's raging thirst for Pinot Grigio was kindled by top-drawer Italians. Mouthwatering, zesty, with deeply satisfying pear and apple flavours, bottles like these stand head and shoulders above the wishy-washy supermarket brands. We found these gorgeous examples from the cooler mountain-ringed regions of Friuli Grave and Venezie in the north, and selected high-altitude vineyards in Sicily.
