My wife opened a bottle of it this past week ('twas a Cab if I recall correctly). She poured a glass, tasted it...let it sit for a minute to open up....tasted it again...
...and then she poured the remainder of the glass down the drain, put the cork back in the bottle, and deemed it "cooking wine".
LOL
Me personally, I don't know shit about wine and I really don't much care for the stuff...but my wife has around 7 or 8 cases of wine in the house at all times, and I'd say she's a bit of a wine person.
I imagine that as cheap as the Barefoot is, it's probably just fine for the casual wine drinker, but would leave a serious wine enthusiast with a bad taste in their mouth.
