I've been buying zins direct from California since the 90's. I started with Turley and added Carlisle. I'm at a place where I'm only gonna buy from one. Turley has been at it forever but I've found Carlisle to be a little cheaper and more consistent year-in and year-out. Parker (or what was Parker) seems to like Turley and the WS seems to favor Carlisle. I know there are other good producers, but they don't seem to last. Think Ridge and Rosenblum. Carlisle has a lot of old-vine vineyards with old grape varietals co-mingled with the zin. Maybe that makes them a little more interesting.
I’m not into Zin anymore. When I was really into Zin, Martinelli was my favorite but was also the most expensive. Carlisle was second. Turley was third (for its top wines); Robert Biale was fourth and Ridge was fifth...
HOWEVER — at the end of my interest in these sorts of wines, the only one I still really appreciated was Rafanelli. I haven’t had one in years, though.
Still love the Rafanelli though I stopped buying a few years ago. Only one I still buy is a split case of Scherrer (Old & Mature Vines and Shale terrace) on their futures program each year to lay down as they age remarkably well
Agree with CSM -- Ridge. But Bedrock is also on my buy list, although it is not often seen in these parts.
