What are the four main grape varieties of Orvieto DOC?

The four main grape varieties of Orvieto DOC are Trebbiano, Grechetto, Malvasia, and Verdello. Orvieto is a white wine appellation located in Umbria, Italy, known primarily for its blend of these varieties, which contributes to the wine's distinct character and quality.

Trebbiano is significant because it forms the backbone of many Italian white wines, offering crisp acidity and a light body, which is desirable in blends. Grechetto, on the other hand, adds a bit more structure and a hint of nuttiness and herbal notes, enhancing the complexity of the wine. Malvasia is valued for its aromatic qualities and can impart floral and tropical fruit notes. Finally, Verdello rounds out the blend with its ability to add a softness and roundness to the palate.

The other options listed include grape varieties that do not represent the primary composition of Orvieto DOC. For instance, Sangiovese and Montepulciano are red grape varieties not typically associated with the white wines of this region. Likewise, while Procanico might be used interchangeably with Trebbiano in some contexts, it is not one of the four main listed varieties in the DOC regulations. Garnacha, Mer
