By the law of 2003 "On vineyards and wine" (Ley 24/2003 de la ViГ±a y del Vino), Spanish wines are classified into two broad categories: table wines (Vinos de Mesa, or VdM), which make up about 2/3 of all wine produced in Spain, and the so-called high-quality wines made in certain regions (Vinos de Calidad Producidos en Regiones Determinadas, or VCPRD). Table wines have a sub-category of "estate wine" (Vino de la Tierra, or VdlT), wine bottles with this marking have the name of the region of production specified.
You may encounter the following types of high-quality wines (VCPRD):
Wines of known origin that have a marking DO on the label. DO stands for DenominaciГіn de Origen, for example, Montsant DO or PenedГ©s DO. By 2012 Spain has around 70 wine regions that have the right to mark their wines with DO. The DO mark means that several conditions have been met with regards to the wine produced: the grapes used in its production have been grown in the region specified, the wine itself has been made in the region specified, and the region has a high market standing.
Wines of high-quality origin have a marking DOCa on the label. DOCa is DenominaciГіn de Origen Calificada (Spanish), also known as DOQ, meaning DenominaciГі d'Origen Qualificada (Catalan). Right now there are only 2 regions in Spain that boast the right to use the marking of DOCa/DOQ, namely, Rioja and the Catalan region of Priorat. DOCa/DOQ signifies the highest quality of wines produced over the course of many years.
Outstanding, exclusive wines are marked with VP (Vinos de Pagos). Pago means "a land patch", and within context of wine classification signals a small land with unique micro-climate and soil qualities, which, coupled with a certain unchanged type of wine-making, creates the ability to make extraordinary wines. There were 12 pago registered in Spain in 2012, and most of them are found in the autonomous region of Castilla - La Mancha.
