Two really wonderful wines, IMHO, are:
*Blackstone
*Bogle
Both are from California, and have Cabernets in their line-up. Of the two, Bogle is the better I think... I've brought it to parties (the Merlot in that case) and people make sure to ask what they are drinking when they try it.
A bottle of Blackstone in my area is $10-11, and the Bogle is $11-13, depending on the store.
Yellowtail is not bad... I like it!
On the other stuff:
Boxed wines though... *shudder* hehehe! I've tried 'em, and no-go for me, they tasted watered down, or like you wished they would be
I didn't like Ravenswood myself either... but to each, their own!
Though I give them credit for a spiffy label! I do like me a pretty label... heh!
