Verdello is a white grape variety with roots in Umbrian tradition, particularly associated with the Orvieto area and historically used in the blend of Orvieto wines. Its presence is documented in viticultural records from the late nineteenth century to the first half of the twentieth century, when it was recorded as a local variety in the Perugia and Orvieto areas. Today it is grown mainly in Umbria, with some cultivation also in Lazio and Tuscany. The leaf is medium-sized, orbicular and generally five-lobed, with a green upper surface and a petiole sinus with overlapping lobes. The bunch is medium or medium-large, pyramidal, winged and compact; the berry, medium-small and spherical, has a pruinose, greenish-yellow skin, sometimes marked by faint brown streaks. Ripening is medium-late. Most commonly vinified as part of a blend with other local white grape varieties, it produces wines with a straw-yellow colour, a clean and pleasantly fruity bouquet, with floral undertones. On the palate, it offers freshness, savouriness and a balanced structure, accompanied by a delicately bitter finish. Its acidity contributes to the dynamic flavour profile and promotes good development over the medium term. An interesting fact concerns its genetic affinity with Verdicchio and Trebbiano di Soave, whilst retaining its own distinctive ampelographic characteristics.
