The seductive 1976 Vina Bosconia Gran Reserva is another ethereal beauty, revealing an expressive nose along with notes of earthiness, sweet perfumed fruit, cocoa, flowers and an occasional hint of white truffle that floats out of the glass. Fresher and more vibrant than the Tondonia Gran Reserva, it offers outstanding length and notable structure in an understated yet profound expression of Rioja. It is that rare wine that invites contemplation by engaging all of the taster’s senses. A great effort.
