Madai operates in Bierzo, the distinctive wine region of Castilla y León in northwest Spain. The winery focuses on two native varieties that define the area: Godello, a white grape of mineral precision and aging potential, and Mencia, a dark-skinned variety known for its structure and complexity. Madai's Godello Sobre Lias represents the winery's commitment to the variety, while its Origen line—available in both Mencia and Godello—demonstrates the range of expression possible within Bierzo's terroir. Both Decanter and Wine Spectator have rated Madai's wines, recognizing the technical quality evident in the cellar's work with these regional grapes.
