Portuguese wine has a long-standing viticultural heritage, shaped by the vast amount of indigenous grape varieties and varied terroirs. Key regions include the Douro Valley, famed for robust red wines and Port; Alentejo, producing rich, fruit-forward reds; and Vinho Verde, known for crisp, light whites. Notable grape varieties include Touriga Nacional, Baga, and Aragonez for reds, and Alvarinho, Loureiro, and Arinto for whites. Portuguese wine styles range from full-bodied reds and aromatic whites to fortified wines like Port and Madeira. Portugal sees traditional techniques blend with modern innovation, which creates wines with character and distinction.
