Ok, guess I should contribute something actually on topic. So:
Out of 445 notes in CT (for about 3+ years now), I only have two producers with 10 or more notes (Karl Lawrence and Neal). I guess that makes me a dilettante who spreads himself too thin

.
Oh well, so here're my results running Eric's query for 4 or more notes/producer:
Ramey (92.0 pts. in 5 notes)
Bodegas El Nido (91.8 pts. in 6 notes)
Pride Mountain Vineyards (90.8 pts. in 7 notes)
Lewelling (90.3 pts. in 8 notes)
Karl Lawrence (89.9 pts. in 11 notes)
Beaux Frères (89.0 pts. in 4 notes)
Neal Family (89.0 pts. in 10 notes)
Rosemount Estate (88.6 pts. in 6 notes)
Georges Dubœuf (88.0 pts. in 7 notes)
Fox Run Vineyards (87.8 pts. in 5 notes)
