The wine region Península de Setúbal also includes a large coastal chunk of the administrative region (as opposed to the wine region) of Alentejo.
Much of the area is flat and sandy, with the exception of the Serra da Arrábida, a short chain of mountains running along the south coast of the peninsula, where the soils are limestone or clay-limestone. The climate is Mediterranean, with hot, dry summers and mild but rainy winters. Vineyards in the Serra da Arrábida are cooler, owing to the higher altitude and the proximity of the sea.
There are two DOCs, Setúbal and Palmela. Setúbal is sweet and fortified, made primarily from the Muscat of Alexandria grape. It can be labelled Moscatel de Setúbal when Muscat makes up more than 85 per cent of the blend. DOC Palmela is mainly red, and based on the late-ripening Castelão grape, which is more at home in the hot, sandy soils of Palmela than anywhere else in Portugal, ripening well to make wines of complexity and depth, elegance an balance, with good cherry fruit.
