Antonio Madeira produces wines from Dão, the granite-bedded heart of Portugal's Beiras region. The winery's portfolio centers on indigenous varieties—Baga, Tinta Amarela, Jaen, and others—that thrive in Dão's cool continental climate and schist-rich soils. A Centenaria, a single-varietal Tinta Amarela, and Os Granitos, a structured blend of five regional grapes, represent the winery's core offerings and have earned recognition from Wine Advocate, Decanter, Wine Enthusiast, and Wine Spectator. Vinha da Serra, a Baga-led blend, rounds out the lineup. These wines reflect Dão's character: mineral precision, firm tannin structure, and the earthy complexity that comes from old-vine plantings on granite slopes. The region's elevation and diurnal temperature swings lend freshness and definition to reds that age with grace.
