I tried wine in a box once... ONCE. My old apartment complex threw a Christmas party and a summer pool party every year, where the only alcohol to be had was wine in a box and a keg of Bud Light. Barf-o-rama.
With the rent they charged, they certainly could have afforded better...
Cardboardonnay - I'll have to remember that
My friends and I usually refer to it and other bad wines as "Chateau le Plonk".
My recommendations:
If you can find it, try Cloudy Bay Sauvignon Blanc. The chardonnay is also very nice.
My fave is Rodney Strong Cabernet Sauvignon, especially with a nice thick medium-rare steak
They also offer a merlot, a chardonnay (one of the few American chardonnays I will drink) and a few others that are escaping me at the moment.
