Suggestions for Natural Napa Cabernet wines

Any suggestions in the $50 to $100 range would be appreciated. I want the wines to pass the Nossiter test. I want to experience how wine is supposed to be made.

Thank you.

Anything from Arnot Roberts will definitely suffice, although most are Sonoma. I am a big fan of the Bugay Vineyard bottling.

Arnot Roberts = no sulfur or under 35 ppm sulfur?
