White Orvieto is a blend composed primarily of Grechetto and Trebbiano and a blend of Malvasia, Drupeggio, Verdello and Canaiolo bianco grapes. Grechetto is valued for the fruitiness and weight that it brings to the wine; some of the most highly rated examples of Orvieto have a high concentration of Grechetto. The wine today is radically different from the historical sweet Orvieto, with off-dry and sweet wines accounting for less than five percent of total production.
