In 1992, Júlio Bastos, wishing to ensure its growth and, at the same time, the distribuition of his wine production, sold 50% of the Sociedade Agrícola Quinta do Carmo to the Domaines Barons de Rothschild (Lafite). It was then that the old winery was transferred from Quinta de Dona Maria, or Quinta do Carmo, to the Estate called Herdade das Carvalhas, which belongs since then to that company.
Never having given up on the idea of again producing his own wine, it was at the beggining of the new millennium that the opportunity arose. Júlio Bastos then decided to sell his shares in the Sociedade Agrícola Quinta do Carmo, and started this new project, Dona Maria wines.
Since the beginning of this project the Dona Maria wines have been recognized, not only by the public but also by opinion leaders. Having achieved high scores in international magazines such as WineSpectator, Robert Parker and Wine Enthusiast, as well as in many international competitions, the Great Gold Medal award, with the wine Dona Maria Reserva 2003, was a great achievement since it had, until then, been the first-ever Portuguese wine to be awarded this distinction.
