Italian term (also vigneto) for vineyard. However, it is also used for subzone, single vineyard, vineyard parcel or growth. Some wineries also prefix Vigna or Vigneto to their estate name (see Azienda vinicola). Vigna is equivalent to the French Grand Cru. In Italy it is used for wines from hilly vineyards. This is indicated on the label with Vigna and site designation. Compared to the normal DOC/DOCG regulations, there are usually even stricter specifications (higher alcohol content, lower yield, etc.). Only officially recognised vineyards may be named. Other designations for qualitatively outstanding sites are Bricco, Colli, Ronco, Serra and Sori. A complete list of vineyard-relevant keywords is included under Vineyard.
