The house usually throws into the Crianza some 15% or so of slightly overripe CS &/or Merlot, but I really don't know if they followed this procedure for their (1st ever) Gran Reserva. I believe there was very little produced and it's horribly expensive here at least...

Really not a clue about export availability...
A much easier option would be the 1999 Reserva after a few years. Some of us commented (rather ungratefully perhaps) that we'd have DIED for a mag of the 99 Reserva which is absolutely stunning wine with lots more fruit now. God knows about its evolution in the future, though.
1996 was the last seriously GREAT Vintage in Ribera so no wonder the guys had their chance for the release of a Gran Reserva, but I guess that made it disappear fairly quickly...
