The hot southern plains of the Alentejo make Portugal's most approachable and best-selling reds — ripe, soft and generous, built on Aragonez (Tempranillo), Touriga Nacional, spicy Trincadeira and the dark, dense Alicante Bouschet. Sunshine and space give wines of easy charm, plump with plum and fig.
Beneath the crowd-pleasers runs a much older thread: some estates still ferment in great clay talha amphorae, a Roman-era method found almost nowhere else. And on the granite and schist, ambitious producers make serious, structured reds. Approachable at every level, the Alentejo is the commercial heart of modern Portuguese wine.
