Italian designation (also vigneto) for vineyard. It is also used for subzone, single vineyard site, vineyard plot or plant. Also some wineries put Vigna or Vigneto in front of their estate name (see Azienda vinicola). Vigna corresponds to the French Grand Cru. In Italy it is used for wines from hilly vineyards. This is indicated on the label with Vigna and the vineyard designation. Compared to the normal DOC/DOCG regulations, there are usually even stricter requirements (higher alcohol content, lower yield etc). Only those sites may be mentioned which are officially recognised. Other designations for qualitatively outstanding areas are Bricco, Colli, Ronco, Serra and Sori. A complete list of keywords relevant to vineyards is included under vineyard area.
