The DOC area (formerly Bucellas) for white wine is located north of Lisbon in the Portuguese region of Extremadura. It is named after the municipality of the same name, where the folk festival "Festa do Vinho e das Vindímas" takes place every year in October. The vineyards cover about 200 hectares of vineyards on soils of calcareous marl and crystalline limestone covered with a thin layer of humus. The acid-accentuated, storable white wine is mainly made from the native variety Arinto, supplemented by Esgana Cão(Sercial). The red wines of the area, mainly from Touriga Nacional, are marketed as IGP (Land wines).
The white wine was praised by William Shakespeare (1544-1616) and mentioned in his drama Henry VI as "Charneco" (after a village). At that time he was considered the "King of Portuguese white wines". Arthur Wellesley, 1st Duke of Wellington (1769-1852), victor over Napoleon at the Battle of Waterloo in 1815, became acquainted with wine as a young officer during the Spanish War of Independence in 1809 and later made it immensely popular in England. Because of its taste similar to riesling, it was called "Portuguese Hock" (Portuguese Rhine wine) there. But this reputation was lost and for a long time there was only one producer. Today it is again produced by several, for example Quinta da Romeira.
