Itxas Harri, located in the village of Monteagudo in the northern Basque region of Navarra, is a project from Ignacio Ameztoi and his long-time friend and winemaking partner, Inaki Guelbenzu. The vineyard is on well-drained, gravelly limestone soils in an ancient seabed at 385m in the Monteagudo village.
Garnacha and tempranillo grapes for Beltza are 90% destemmed and given a brief pre-fermentation cold soak. The wine is then fermented with native yeasts in temperature-controlled stainless steel tanks, with maceration throughout. It then ages in stainless steel until bottling the following spring.
