Personally, I love cork and I even love the corks that aren't even made out of cork anymore but some sort of plastic rubber cork. Drinking wine out of a box or screw top to me is like getting a fine seafood experience at Long John Silvers.
I am a huge fan of the muscadine wines. NC goes crazy for them and I have sort of adopted that taste.
It takes all kinds. Muscadine grapes are considered inferior and gross by wine snobs. Go figure.
Barefoot is mass produced. But you know what's good, the Riesling with the really long German name that comes in the blue bottle with the sun on it. Every store seems to have it, and its a bit effervescent. It's not super quality but it's really tasty.
A famous and well-respected winery in CA called Bonny Doon only does screwtops now, because cork is unsanitary and can rot. The artificial corks are fine with me but some people look down on them. It's all in what you like.
In my experience, I can usually get an Argentine wine from Mendoza, a Chilean red, New Zealand or Australian white, or a Torrontes and go home happy without much fuss.
