Quinta de Sant'Ana produces red wines in Lisboa, Portugal's dynamic wine region. The winery draws on indigenous Portuguese varieties—Touriga Nacional and Aragonez—alongside Merlot to craft structured blends and single-varietal expressions. The Homenagem Baron Gustav von Fürstenberg, a blend of Merlot, Touriga Nacional, and Aragonez, represents the house's top expression. The Reserva follows a similar composition, while a dedicated Touriga Nacional bottling showcases the grape's dark fruit and tannin architecture. These wines have been assessed by Wine Enthusiast, Wine Advocate, Wine Spectator, Decanter, and Falstaff.
