Located in the village of Navaridas at an elevation of 500 meters above sea level is the vineyard where Olivier Rivière makes what he considers his Grand Cru Rioja – Losares. This site was planted in 1930 on decomposed sandstone and limestone soils. Typical of many older vineyards in Rioja, it is planted with a wide array of red and white varieties, with Tempranillo the dominant variety. Losares is a blend of Tempranillo, Graciano, Mazuelo and small percentages of the remaining red varieties.
