The 56 hectares of vineyards are spread over the clay-limestone soils of the gentle hills typical of the region, which gave rise to its name. The farm's wine cellar uses the most modern winemaking technology, moving all liquids and masses by gravity. The tradition of the Bairrada terroir and the team's savoir-faire translate into a rich and broad portfolio that includes the brands: PRINCIPAL, COLINAS and SÃO LOURENÇO.
