The axes that can be heard in the summer months throughout the cork-oak woodlands, or montados, of Portugal's Alentejo region have long fallen silent. The annual harvest is over, and the trees that have yielded their bark are beginning the decadelong process of regenerating their corky cladding. Across the vineyards of Southern Europe, the final grapes have been picked for the new vintage. One day the products of these two harvests should come together in a wine bottle.
