the 20th century plantings of Verduzzo were on the decline, there were still 1658 hectares (4,097 acres) planted throughout Italy in 2000. The majority of these plantings were found in the eastern province of Udine in the Friuli-Venezia Giulia region, particularly around the communes of Nimis, Faedis, Torlano and Tarcento which have all had a long history associated with the grape. Outside of Friuli, significant plantings of Verduzzo can also be found in the Veneto along the banks of the Piave river and around the town of Pramaggiore. Verduzzo is permitted in several of the Friuli DOCs-Colli Orientali del Friuli, Friuli Annia, Friuli Aquileia, Friuli Grave, Friuli Isonzo and Friuli Latisana as well as the overlapping Lison Pramaggiore DOC that extends into the Veneto. It is also grown in the Collio Goriziano DOC zone, however, it is not a permitted variety and wines made from this grape are labeled as vino da tavola. Also within the Veneto, Verduzzo is authorized for the Piave DOC. Within the Colli Orientali del Friuli, the grape is used to make sweet wines in the Ramandolo DOCG. In Ramandolo, the grape is mostly commonly found on the steep hills that sit around 380 meters (1,250 feet) above sea level that circle the commune of Nimis. DOC requirements Outside of Ramandolo, most of the DOC wine produced by Verduzzo are labeled under the Friuli Grave and Colli Orientali del Friuli designations. Under Italian wine law, each DOC has its own specification for how each grape variety can be used in order for the DOC name to appear on the wine label. For example, in the Friuli Aquileia DOC, Verduzzo can be produced as a varietally labeled wine provided it makes up at least 85% of the blend from grapes that have been harvested at a yield no greater than 12 tonnes/hectare and the finished wine attains a minimum alcohol level of at least 11%. In the , a varietal Verduzzo can be made with at least 90% of the variety and other local white grape varieties such as Friulano (Sauvignon vert), Ribolla Gialla, Pinot bianco, Pinot grigio, Sauvignon blanc, Riesling Renano and Picolit permitted to fill in the remainder. (Other Friuli DOCs will often add Chardonnay, Malvasia, Müller-Thurgau, Riesling Italico and Traminer Aromatico to the list.) Any grapes used must be limited to a maximum harvest yield of 11 tonnes/ha with the finished Verduzzo wine having
