Quinta do Monte d'Oiro, located in Alenquer, is a benchmark project in Portuguese viticulture, especially recognised for its inspiration in the French Rhône tradition. Founded by José Bento dos Santos, a businessman and gastronome with a passion for wine, the estate has become a place of innovation and excellence. The philosophy centres on producing terroir wines that authentically express the region's clay-limestone soil and microclimate, marked by the Atlantic influence. The focus on national and international grape varieties, such as Syrah, planted in the 1990s and today a true icon of the house, has given Quinta do Monte d'Oiro a solid reputation in Portugal and beyond. The work on sustainability, respect for the environment and organic viticulture practices reinforce the identity of the project, which combines modernity, tradition and a cultural vision of wine.
