Olive oil of the royal variety Food and drink · Alloza, Andorra-Sierra de Arcos, Teruel Image of Alloza, not of the place itself. Alloza preserves olive groves of the royal variety, little grown outside a few inland comarcas. It gives a golden, mild-tasting oil, different from the empeltre that dominates in the rest of the Bajo Aragón. Photo: Ecelan (CC BY-SA 4.0) What to see and do in Alloza
