The Setúbal Peninsula, located south of Lisbon, is one of Portugal's most distinctive wine regions, recognized for its Protected Geographical Indication (PGI). Nestled between the Atlantic Ocean and the Arrábida mountains, this region benefits from a temperate Mediterranean climate, ideal for viticulture. It is particularly renowned for its fortified wines, notably the Muscat of Setúbal, a sweet and aromatic wine appreciated for its notes of raisin, caramel, and honey. In addition to Muscat, the Setúbal Peninsula also produces high-quality red and white wines, made from native grape varieties like Arinto and Castelão, as well as international varieties such as Cabernet Sauvignon and Chardonnay. The diversity of soils, ranging from sands to calcareous clays, adds extra complexity to the wines from the region. With a winemaking history dating back to Roman times, the Setúbal Peninsula continues to surprise and delight wine enthusiasts worldwide with its rich heritage and unique flavors, making it an essential discovery for anyone passionate about wine cellar management.
