The 400-hectare estate of Can Sumoi sits at six hundred meters of altitude in the Serra de l'Home range in the Penedès. Its 350-year-old farmhouse and stone walls accommodate thirty hectares of old Montonega, Xarel-lo and Sumoll vines; stands of oak and white pine shade the rest of the surface. The vines are cultivated on limestone soils in certified-organic fashion and the resulting wines are produced without additives, stabilization or filtration (although no sulfur is added, trace amounts remain in the wines as natural fermentation by-product). They show low alcohol and refreshingly brisk acidity.
