Wine in 7-Eleven store

Wild Horse Pinot Noir may seem like a world away from the Big Gulp, but you can find both drinks in many 7-Elevens these days. The world's largest chain of convenience stores, known more as a go-to destination for a six-pack of beer or a cup of Joe, has suddenly embraced upscale wine.

The company recently started selling four so-called ultra-premium wines (the category priced at $15 to $19.99), all of them well-known, including Kim Crawford Sauvignon Blanc from New Zealand and La Crema Chardonnay, Louis Martini Cabernet Sauvignon and the Wild Horse Pinot Noir from California.
