Orvieto is the most important wine appellation for white wine in Umbria. The wines produced in the region are based on Grechetto (minimum 60%), while the blends often also include Trebbiano Toscano (locally known as Procanico) or other permitted white varieties.
Although the appellation also covers sweet wines—including noble rot style Muffa Nobile and late harvest Vendemmia Tardiva—which were once flagship styles, modern production is mostly oriented towards light and approachable dry white wines.
They can also have a slightly bitter aftertaste. The appellation covers the Classico label produced from the grapes cultivated in the oldest and best locations around Orvieto and the Superiore label that has to be aged for at least four months and reach 12% ABV.
