Utterly unique! This is a hybrid style of white Rioja from the fabled Cvne winery that hadn't been produced since the '70s until this vintage. The Viura wine is topped off with Manzanilla Sherry purchased from the Hidalgo family of Sanlúcar de Barrameda (this is the same sherry and source Cvne used back in the old days). The sherry was purchased in its original sherry casks, which were used to further age the Viura. This is not like using a wine barrel to age a whiskey where the barrels influence is subtle! The result is awesome and unmatched elsewhere in Rioja; it starts out like a fresh white Rioja before the sherry takes over. The finish is totally dry but goes on for days in a savory, nutty fashion.
