Check out this superb article, about Calera's Pinot noir's back bottle label:
The above photo shows only the front label, but the back label is a treasure trove of fascinating information about the wine. And this is a very special wine, by the sound of it (once you've read the back label). My only quibble is that I don't think that less-concentrated vine spacing brings lower yields; in fact I would expect the opposite. I think it is the high-elevation and limestone soil which retard the yield. And I totally agree that his own-rooted vines (as opposed to grafted rootstock) probably would yield more and better flavors.
In case you're interested: I've not heard of this one. It's small production and likely not available at wholesale.
