Very interesting OP. For a number of reasons I have done a couple of very high end cull parties recently, popping bottles until we found something that really hit home. A bunch of things I always thought I liked fell completely flat.
When I looked at the carnage, it was clear that I spent too much $$ buying across producer ranges. Certain folks are very skilled with certain grapes (to my palate), and their other wines do not move me. Every Syrah made by Pax that I opened stood up and made a positive impression. Unfortunately his Wind Gap Pinots did not. I had enjoyed a few of those wines in the past, but they did nothing for me. Note to self - only buy Syrah from Pax. I had a similar experience with Ramey. I love what David Ramey does with Chardonnay, and think his Cabernet wines are also excellent. His Pinot does absolutely nothing for me. Buh-bye. More selectively, I like what Jamie Kutch does with Pinot Noir, but have discovered that I so vastly prefer Falstaff to his other vineyards, that it makes no sense to buy anything else (other than his Chard which is delicious). Meanwhile, other producers are making Pinot Noir that hits the right place for me. Rhys of course is on that list (though I do not much care for Family Farm or Bearwallow). John Lockwood at Enfield is making Pinot Noir from the Antle Vineyard that impresses me. I was recently introduced to Goodfellow on Berserker Day, and one bottle so far has been excellent.
