DOC or DOP (Protected Designation of Origin)
DOP applies to wine products with originality and individuality due to an inextricably link to a particular region, place or traditional denomination with specific characteristics deriving from the local terroir (geographic environment, natural and human factors).
These wines are subject to strict rules of control in order to guarantee authenticity and quality and can be labelled as DOC.
Protected Designations of Origin for European wines are included in a European Union register.
IG or IGP (Protected Geographical Indication)
IGP applies to wines from a specific region named on the label, produced with at least 85% of grapes of that region. Like DOP/DOC wines, they are subject to strict rules of control.
These wines can be labelled as “Vinho Regional”. Protected Geographical Indication for European wines are included in a European Union register.
Wine not fitting into the above categories is simply known as ‘Vinho’.
They must comply with National and European Union regulations.
