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.
