Valdespino is the most historic house and one of its most traditional producers. The estate dates back to 1264 when Don Alfonso Valdespino was rewarded with land for his role in helping to oust the Moors. Its crown jewel is the Macharnudo vineyard, with the highest vines in Sherry. Its limestone clay soils are born from a band of chalk subsoil, and it is this chalk that limits yields and gives Macharnudo fruit its characteristic mineral intensity. Valdespino is widely known for the care and length of aging its wines.
