The Monte Alto Estate is one of the historic estates in the province of Valladolid, dating back to the time of the monasteries, when the Cistercian Order arrived in Spain, bringing with it the culture of wine. The Monastery of Santa María de Valbuena is located very close to the Estate, in San Bernardo. Later, with the confiscation of Mendizábal, it passed into the hands of the Marquis Alonso Pesquera, one of the largest landowners in the area.
It was in 1981 when the married couple Manuel Esteban Casado and Mª Ángeles Martín de la Rosa bought the Monte Alto estate, which has an exceptional location between Valbuena and Pesquera de Duero. They had a clear vision of converting this agricultural and livestock estate into a wine estate where they could devote themselves to producing wines of the highest quality.
Manuel Esteban Casado was a great entrepreneur, president of Real Valladolid and president of the Association of Hunters and Fishermen of Valladolid, and he was also very involved with university sport. He had always enjoyed the world of wine and passed on his enthusiasm for this activity to his family. After some experiments, twenty hectares of the Tinto Fino variety were planted in 1987.
