Blackberry is our favorite of the four new flavors. There's a mellow blackberry flavor to this drink, which, like all flavors of Hint, is unsweetened. It's a very enjoyable mix, with just enough of the blackberry flavor to satisfy your palate. And, unlike some of the other new flavors, this one finishes clean as the blackberry flavor fades out nicely. The same can be said about the design of the label, which relies on a blackberry graphic as the lone visual element.
