Just an additional note on the history of the grape...as stated below, it is widely believed to come from the Pinot or Greco family, but some sources conclude otherwise. Some maintain that it comes from a wild native variety domesticated by the Etruscans living in Capua (a city in the province of Caserta). It has similar etymological origins as some of the primitive Lambruscos (Aspro and Cruet) and was cultivated in the same way (vines trained to live supports such as trees, in the case of Asprinio, poplar trees) as many of the Lambruscos from the Po River Valley. So there.
