Basically, it's grape soda, but Vignette sodas are made with Chardonnay and Pinot Noir grapes. The sodas have no added sugar, no high fructose corn syrup, and no caffeine (which is sort of a downer for me, but I can live with it for one bottle).

Really like the Chardonnay version. Great refresher when you need a drink to go with an expensive sandwich.
