I tried this earlier today:
Brand: Sky Valley Organic Root Beer.
Origin: Danville, VA.
Purchase Place: Whole Foods, St. Paul, MN.
Sweetener: Organic Cane Sugar.
Review: This was terrible. Down right horrible. There was an odd sharpness to it, and I think it was from the sea salt and/or the apple cider vinegar found in the ingredients list. I thought the apple cider vinegar COULD be an interesting addition, but it made the root beer a little bitter. I only had a few sips - it was one of the worst sodas that I've had in a while. So this makes 2 horrible root beers that I'd have lately. I've got to change that soon...
Score: 1.5 out of 10.
