The nice thing about RJS, is that if a RQ is very popular and they can continue to source the juice, they will make it part of the regular lineup in the Cru Select line. Some notable RQs that are now regular are:
Australian Bush Vine Grenache
Italian Brunello
Italian Valpolicella Ripassa
New Zealand Unoaked Chardonnay
Okanagan Valley Red Meritage
There are others, but I'm too tired to remember them all now. Sadly, some of the better ones, never make it due to limited juice resources. The Spanish Monastrell Cabernet from 2006 was one of the best RQs I've ever done, and was never to be seen again. I still have 3 bottles left that I jealously guard.
