Verdicchio (, also , ) is a white Italian wine grape variety grown primarily in the Marche region of central Italy. The name Verdicchio derives from verde (or "green") and refers to the slight green/yellow hue that wines made from the grape can have. Verdicchio is the principal grape behind two Denominazione di Origine Controllata (DOC) wines produced in the provinces of Macerata and Ancona, Verdicchio di Matelica and Verdicchio dei Castelli di Jesi. In addition to producing still wines, Verdicchio grapes are also used to make sparkling wine and straw wine. History Verdicchio has had a long history in the Marche region of central Italy with documents noting its presence there since at least the 14th century. Despite its sensitivity to climate conditions and propensity to produce variable yields of variable quality wine, Verdicchio was a very popular planting in central Italy with an estimated 65,000 hectares planted in the mid-1980s. These figures made Verdicchio the 15th most planted variety of any grape in the world, ahead of well-known varieties like Chardonnay, Pinot noir, Sauvignon blanc and Sangiovese. While ampelographers believe that Verdicchio is probably indigenous to the Marche, there appears to be a genetic relation to Trebbiano and Greco grape varieties. In particular, the clones of Trebbiano grown in Lombardy and Soave show very close similarities to Verdicchio while genetic evidence has shown that Greco was probably an ancestor vine to nearly all of Italy's native white grape varieties. Wine regions While Verdicchio is widely grown throughout the Marche, Umbria and Lazio regions, it is most often encountered in the DOC wines of Verdicchio di Matelica and Verdicchio dei Castelli di Jesi. Castelli di Jesi, located around the commune of Jesi in the Ancona province, is the larger of the two areas and tends to produce a higher volume of wine. In Matelica, located in the nearby province of Macerata, the yields for Verdicchio are more restricted under DOC regulation with the best vineyard locations situated along hillsides of the Esino valley. DOC regions The following is a list of DOCs that include Verdicchio as a permitted grape variety, along with other grapes that may be included in the blend in varying percentages that are regulated under the DOC label. The wines for which Verdicchio must account for a majority of the blend are in bold. Cerveteri DOC (Latium) – Primarily Trebbiano, Romagnolo, Moscato Giallo and Malvasia with
