Gravner Breg 2004.  Sandrone Barolo 1989.  Ornellaia 1993.  These are not wines that you normally see offered by the glass at any restaurant, anywhere in the world.  But Del Posto has been offering these options by the glass for several months now, in addition to many other wines of similar stature.  Eater reached out to Del Posto Wine Director Jeff Porter to find out more details.
