Paul Draper also has made some excellent Mourvdre (labelled Matar) at Ridge over the years -- some from the same source as Cline, I believe. So the potential is out here -- you just have to get the right vineyard and producer.
I had a nice ATP Mataro from old vines in Sonoma County (I think) from the final year before they got ripped out for a subdivision that was very nice, circa mid-90's(?). I'm sure those vines would be worth their weight if they kept them. Can't vouch for the houses.
