Used to visit Napa/Sonoma/Mednocino when I lived in the Bay area many years ago. Visited Opus when it first opened with many others such as Jordan, Heitz, Diamond Creek, etc., all the biggies…
For moderate price, I second the dry creek Zin recommendation. there are many other excellent Zins made in the Dry Creek valley.
Also like Williams Seylem Pinot Noir, kinda pricey but IMO worth it, need to get on the list though…
