Founded in Viana in 1986, Bodegas Ondarre belongs to the Grupo Bodegas Olarra, one of the most renowned consortia within the D.O.Ca. Rioja. Ondarre is a smaller-scale winery with lower production than the group's original winery (Olarra), and it specializes in the production of reservas. Additionally, it produces a barrel-fermented white wine and some cavas. Attention to detail is one of the keys to the success of its wines, which have maintained high standards of quality since their inception.
