Do you see many Crusted Ports anymore? I have only seen one bottling (Dow's 2000) at one store in the many wine shops I've visited in the DC area and elsewhere.
I agree on the Warre's 1995 LBV, although it is unfiltered so there is some inconvenience.
For filtered ports, you are in good shape if you can find Taylor's 2000 LBV or Dow's 2000 LBV. Unfortunately, 2001 has replaced the 2000 for most LBVs I'm seeing on the shelves.
