We discovered Naked Winery last fall in Custer, SD of all places. My wife and I have been to several wineries since (and she's been to Napa at least once), but we still talk about what a neat find Naked was.
They have a wide variety of really risque-sounding, but very delicious wines. While my wife prefers the reds, I lean more towards white. We tasted many of them, but there was just something really good about the Wanderlust. I've already ordered two cases of it since our trip, and when I offer it to our guests, you can see the "Really, wine from a plastic bottle"-look on their faces, but that quickly goes away once they have some.
These are great for days at the beach or lake. If you like your wine chilled, just toss them in the cooler with the other drinks and go. I've dropped at least one bottle on our patio (in bare feet) and just had to chuckle when it bounced and I didn't wind up having to pull shards of glass out of my toes.
