Vin de pays
In addition to the top-level DOC designation, there are two secondary tiers: "Indicação de Proveniência Regulamentada" (IPR) and "Vinho Regional." IPRs are similar to DOC "in training" and indicate regions that have established their own regulating bodies but have not yet established an internationally recognizable identity for their wines. It is similar to the French "Vin Délimité de Qualité Supérieure" (VDSQ) system. Vinho Regional is similar to the French "Vin de pays" and is sort of a "catchall" classification for wines that do not qualify under the DOC or IPR designations.
