Companhia das Quintas operates in Alentejano, Portugal's expansive southern wine region, where warm continental conditions and diverse soils produce structured red wines of depth and aging potential. The winery's portfolio centers on traditional Portuguese varieties. Uniqo Superior blends Touriga Nacional, Tinta Roriz, and Touriga Franca into a wine that has drawn assessment from Wine Advocate, Wine Spectator, Wine Enthusiast, and Decanter. The Uniqo Grande Reserva follows a similar varietal framework, while Monte Novo Reserva Tinto shifts toward Trincadeira, Alicante Bouschet, and Aragonez—grapes that thrive in Alentejano's heat and contribute darker fruit and tannin structure. These wines reflect the region's capacity for bold, age-worthy reds built on indigenous Portuguese grapes rather than international varieties.
