2021 Vintage- At Marqués de Riscal, there used to be “winemaker’s wines” among its historic reservas, like the Reserva Medoc and the XR, which never became commercial names. In the tradition of the cellarmasters from Bordeaux that have long been part of Riscal’s story, the winemaker marked some of the barrels in chalk with the letters XR (Extra Reserva) as a consequence of having found special characteristics which were not present in other wines. These wines were never sold but served as a reference point for the winemaker. This custom lasted almost a century, between the harvests of 1869 and 1964. In 2015, Marqués de Risca released a wine named XR, paying tribute to all the master winemakers who have helped to forge a part of the greatest history of Spanish wine in Marqués de Riscal.
