Vintage 2023 Founded in 1920 by the Costa brothers, Caves São João became a key player in Portuguese winemaking with its iconic brands "Frei João" from Bairrada and "Porta dos Cavaleiros" from Dão. Initially focused on fine Douro wines, the winery shifted to Bairrada table and sparkling wines after a 1930 regulation restricted Port production. Under French enologist Gaston Mainousson, Caves São João gained a reputation for quality wines. Though demand for Bairrada and Dão wines waned in the 1990s, they saw a resurgence 20 years later as consumers sought finesse and freshness. In 2013, the Costa family began releasing library vintages from 1959 to 2000, showcasing the remarkable aging potential of their wines. Today, Caves São João remains the only Portuguese winery to offer such historic vintages commercially, blending tradition with continuous innovation. A red sparkling wine from Bairrada made from Baga, Touriga Nacional and Cabernet Sauvignon. Bairrada has a long tradition of sparkling wine production, and its cool Atlantic-influenced climate naturally supports grapes with high acidity and moderate alcohol, making it especially suited to this style. The combination of native Portuguese grapes with Cabernet Sauvignon gives the wine both regional identity and a distinctive savory, peppery edge.
