The most enjoyable current release Napa Cab I've had in a while is:

- marketed by Gallo
- not overextracted, over-oaked, sweet, or otherwise unnatural tasting
- an historic California producer

And the wine is....LOUIS M. MARTINI CABERNET SAUVIGNON NAPA RESERVE 2004

Yes, it's far from a cool wine to like, it's a Gallo product, is probably not made from organically farmed, hand picked grapes, and is probably made in massive quantities. Doesn't matter as I think the wine is fun, quite natural tasting, reasonably priced, and reflective of a type of style all but lost in Napa Valley. Go buy a bottle (it's probably a very easy find) and see what you might be missing.
