DOC area for white wine in the border area of the Italian regions Umbria and Lazio. The zone covers about 2,500 hectares of vineyards in the municipalities of Allerona, Alviano, Baschi, Castel Giorgio, Castel Viscardo, Fabro, Ficulle, Guardea, Montecchio, Montegabbione, Monteleone d'Orvieto, Orvieto and Porano in the province of Terni (Umbria), and Bagnoregio, Castiglione in Teverina, Civitella d'Agliano, Graffignano and Lubriano in the province of Viterbo (Lazio). Humidity in autumn causes fog and thus noble rot. The Etruscans were already cultivating wine here and Orvieto wines had a legendary reputation in the Middle Ages. The painters Pinturicchio (1454-1513) and Luca Signorelli (1441-1523) demanded rations of wine as part of their fee for their work in the Sistine Chapel and the Cathedral of Orvieto. Pope Gregory XIV (1535-1591) also greatly admired him and decreed in his will that his body should be washed with it before burial.
