The history of Protos dates back to 1927 when 11 vine growers established the “RIBERA DE DUERO” winery, with a progressive vision to prepare quality wines with a commitment to brand value. Ninety years later, this spirit not only lives on, but also flourishes year upon year. At Protos, we have always taken pride in our roots, using only our native variety, the Tempranillo, and in 1982 allowing our brand “RIBERA DE DUERO” to be used for the recently established Ribera del Duero Denomination of Origin. Today Protos is the leading winery in Ribera del Duero with 3 wineries in Ribera del Duero D.O. for the elaboration of our red wines, 1 in Rueda D.O. for the elaboration of our white wines & 1 in Cigales for the elaboration of our rosé wines and clients in around 100 countries, we continue our international growth with the help of a solid distributor network and in-house staff in the main international markets including the USA, UK, Germany and Asia.
