Since the initiation of Familia Martinez Zabala's project in Ribera del Duero, the committed team, led by the current winemaker Raúl Quemada, has been looking for the finest vineyards in different altitudes and with diverse soils. The architectural genius of the winery aligns with their commitment to sustainability. The unique construction of the building allows to utilize of gravity for grape transportation and minimizes the need for excessive movement of wines. An extraordinary barrel hall, situated below ground level, provides natural and optimal conditions not only for aging wines but also for crafting wines without stabilization and with reduced sulfite levels, thanks to its consistent temperature. The winery features small fermentation tanks to facilitate a meticulous extraction of grape aromas.

Each of Bodegas Portia's premium wines, categorized under Vinos de Autor, embodies the winemaker's distinctive style and reflects the unique characteristics of the terroir.
