The quality requirements for a Vino de Pago correspond to those for a DOCa wine, and wine estates that are classified as Vino de Pago are subject to separate requirements rather than those of the wine region where they are located.[1] One of the requirements is that the estate may only use their own grapes for their wines. The Spanish word pago comes from the Latin word pagus, meaning a country district.
When introduced, the new regulation met with particular interest in Castilla-La Mancha, where the first Vinos de Pago were created. So far, all Vinos de Pago are located in Aragon, Castilla-La Mancha, Castilla y León, Navarra and Valencia.
