About 75% Tempranillo the rest Mazuelo, Garnacho, and Graciano. While a winemaking revolution has raged around them, a handful of bodegas have stayed true to the traditions that made Rioja famous. Perhaps the best known of these in the United States is López de Heredia. Little about López de Heredia has changed in the more than 130 years since its founding. It occupies the same historic cellars and unlike most of their competitors, which are now owned by outside investors, López de Heredia is owned—and every detail of its operation is handled—by the family who founded it. Most Rioja wineries buy grapes from dozens of small growers; but not López de Heredia. They own every inch of the vineyards that supply their wines. Only natural yeasts are used and there is no filtration. They still age their greatest wines in wood for six to eight years and even make their own barrels. The bodega is now in the capable hands of the family’s youngest generation—Maria José and Mercedes. Yet, still, nothing changes. In fact, these two are philosophically committed to the winery’s traditions as their parents and grandparents were before them. This vineyard is 2 miles away from the winery at an altitude of 1,348 feet above sea level; the vines are an average age of 40 years of age. The soil is composed of clay and limestone. The surface is 24 hectares, and is planted to Tempranillo, Garnacho, Mazuelo and Graciano. Historically the wines from that vineyard were called "Special Harvest", but are now the source of their Viña Cubillo. This Crianza is a superb red wine that is of a style that is going extinct is exactly what Lopez de Heredia is all about. Tradition.
