Xisto, a singular, new, limited production, ultra-premium red wine from Portugal, is the fruit of a long-standing friendship between the internationally renowned Bordelais wine producer Jean-Michel Cazes and Jorge Roquette, owner of the highly acclaimed Quinto do Crasto estate in Portugal’s Upper Douro Valley. The Roquette family has played a highly instrumental role in the revitalization now underway within Portuguese wine industry.
