Real de Aragón works within Calatayud, a region in Aragón known for its continental climate and high-altitude vineyards. The winery focuses on Garnacha, the indigenous grape of northeastern Spain, which thrives in Calatayud's demanding terroir. Garnacha from this region typically expresses dark fruit character and mineral tension, shaped by the area's slate and limestone soils. Real de Aragón's Garnacha has drawn assessment from major critics including Falstaff, Wine Advocate, Wine Enthusiast, Wine Spectator, and Decanter. The wine reflects the precision and structure that modern Calatayud producers have brought to this historic variety.
