Portugal is located on the western edge of the Iberian Peninsula and is one of Europe's oldest wine- producing countries. Its wine regions reflect strong contrasts in climate, terrain, and tradition, shaped by Atlantic influence in the west and more continental conditions inland.
Northern regions such as Minho, Tras-os-Montes, and Douro are defined by rugged landscapes and river valleys, with the Douro internationally known for fortified and table wines. Central regions, including Beiras and Tejo, combine inland plateaus with river-based agriculture. Southern areas such as Alentejano and Algarve are warmer and drier, supporting broader-scale viticulture.
Portugal's Atlantic islands, the Azores and Madeira, form part of the national wine landscape, producing distinctive volcanic and fortified wines that differ markedly from mainland regions.
