Quinta do Quetzal produces wines from Alentejo, Portugal's warm southern region known for bold reds and structured whites. The winery's Reserva Tinto blends Shiraz, Trincadeira, and Alicante Bouschet into a wine of depth and power. The Família Grande Reserva Tinto pairs Shiraz with Alicante Bouschet for a similarly concentrated expression. Both have drawn attention from Wine Enthusiast and Wine Advocate. The Reserva Branco, made from Antão Vaz, offers the region's characteristic white character—mineral and textured. Alentejo's continental climate and granite soils shape these wines: ripe fruit, firm tannins, and the ability to age. Quinta do Quetzal's portfolio reflects the region's shift toward quality-focused winemaking and international grape varieties alongside traditional Portuguese cultivars.
