Spur of the moment trip to Napa/Sonoma

Going to be in the area for the next week. Would like to line up some tastings for high-quality sub $100 Cabernet. Forman, EMH and Togni are already on my radar. Looking for some other suggestions. Thanks in advance.

Alpha Omega! Hit up Jean in advance.

Schramsberg. They are better known for their sparkling wine, but their J Davies Cab is excellent.

Based on your choices I would look into Corison. Similar profile to your other choices and a nice place to visit. Friendly folks and some really cool old vines.
