Valduero is a family winery and was one of the first to be founded in the D.O. Ribera del Duero. It was created by Gregorio Garca lvarez in the small village of Gumiel de Mercado, which is located 16km to the northeast of Aranda de Duero, right in the heart of Ribera del Duero, in the province of Burgos. At that time, there were only about half a dozen wineries in the region and despite its long tradition of winemaking and the reputation among connoisseurs for the quality of its wines, it was largely unknown to the general public. The Consejo Regulador of D.O.Ribera del Duero was created at about the same time.
