Cartuxa is a wine producer based in Alentejo, Portugal's largest wine region by area. The estate focuses on white wine production, drawing on the distinctive terroir of southern Portugal's warm continental climate and varied soil compositions.

Alentejo has emerged as one of Portugal's most dynamic wine regions over the past few decades, known for producing both traditional and innovative wines that reflect the area's Mediterranean influences and continental conditions. The region's producers work with both indigenous Portuguese grape varieties and international cultivars, adapting to the challenging heat and drought conditions through careful vineyard management and modern winemaking techniques.

Cartuxa's current offering includes a white wine made from Antão Vaz, a traditional Portuguese variety grown throughout Alentejo. This grape is valued for producing fresh, mineral-driven whites with good acidity despite the warm growing conditions of the region.

Alentejo is Portugal's largest wine region, covering roughly one-third of the country's territory in the south-central interior. The region extends from the Spanish border eastward to the Atlantic coast, encompassing vast plains dotted with cork oak forests and olive groves. Historically an agricultural heartland, Alentejo has emerged as one of Portugal's most dynamic wine regions since the 1990s, transforming from bulk wine production to quality-focused viticulture.

The region experiences a Mediterranean climate with hot, dry summers and mild winters, moderated by Atlantic influence in western areas. Soils vary considerably across the expansive territory, ranging from granite and schist in the north to clay and limestone formations elsewhere. Alentejo is divided into eight sub-regions, including Portalegre in the north, known for higher altitude vineyards, and Évora in the central area, which encompasses much of the region's wine production.

Alentejo produces both red and white wines, with indigenous Portuguese varieties playing a central role alongside international grapes. Traditional red varieties include Aragonez, Trincadeira, and Alicante Bouschet, while white wines feature grapes like Antão Vaz, Arinto, and Roupeiro. The region is known for its approachable, fruit-forward style, with reds typically showing ripe berry flavors and moderate tannins, while whites tend to be fresh and aromatic with good acidity.
