The quality and prestige of Azorean wines have been recognized for a long time, resulting in the recognition of three Indicações de Proveniência Regulamentada (Indication of Regulated Provenance) for the wines of Pico, Graciosa and Biscoitos.
•
The Pico IPR wine is a white wine produced from grapes grown on the rocky soils, located along the western coast of the island.
•
The white Graciosa IPR wines are produced from similar currais of Pico, although other variants are cultivated in more secluded areas.
•
The prestigious white wine of the Biscoitos IPR is produced from the dark and rocky volcanic soils on the island of Terceira, marked by bread-like rock formations that allowed the protection from the intemperate climate in the area.
