An arínzano is an agricultural estate that showcases unique vineyards, and this winery was the first estate in northern Spain to be endowed with the prestigious Vinos de Pago classification. The term pago is a nod to the Greek “pagus”, or property. The idea behind these wines is that they are entirely unique because of their provenance, or terroir, in wine geek speak. In sum, pago equals prestige, as the classification is set up.
