Orvieto

Recognized since 1973, the Orvieto designation spans eighteen municipalities, including Allerona and Alviano, with vineyards situated primarily in Umbria. Distinct from neighboring Italian white wine appellations that market aged versions, Orvieto regulations explicitly forbid the use of the term "riserva" on labels. Instead, territorial character is defined by a mandatory blend of at least 60% Trebbiano Toscano and Grechetto. Furthermore, the "Classico" designation is strictly restricted to grapes grown and vinified within the older historic zone established by a 1931 decree. For late-harvest styles like "Vendemmia Tardiva," picking cannot begin before 1 October, resulting in a delicate, straw-yellow wine.
