I tasted a few great Spanish wines by the glass from the self-serve Enomatic wine dispensers at one of Miami's really authentic Spanish restaurants, Xixón.  My favorite for both quality and value was another impressive entry from the Montsant region, the Faunus 2011, by Ediciones i-Limitadas.  Another great value Spanish wine from the Montsant region.  I love this region for its intense, earthy balanced reds.  Though perhaps not as consistent and remarkable as neighboring Priorat's more famous wines, they're also a lot less expensive in general.
