EVENA, Estación de Viticultura y Enología de Navarra Food and drink · Olite/Erriberri, Zona Media, Navarra Image of Olite/Erriberri, not of the place itself. Founded in 1981 as a publicly owned company of the Government of Navarre —known until 1986 as Evensa—, the Estación de Viticultura y Enología de Navarra (Navarre Viticulture and Oenology Station) is based in Olite, on the foundations of an old winery. It is dedicated to quality control and wine-growing experimentation, and carries out the analyses and tastings for the Consejo Regulador (Regulatory Board) of the Denominación de Origen Navarra. 1981 Photo: JnCrlsMG (CC BY-SA 4.0) What to see and do in Olite/Erriberri
