I cracked into this recently:
Brand: Yacht Club Grape Soda.
Origin: SOMEPLACE, Rhode Island.
Purchase Place: "Minnesota's Largest Candy Store," Jordan, MN.
Sweetener: Cane Sugar.
Review: Initially, it had a bit more of a "bite" than I'd like a grape soda to have. I want a sugary, smooth, sweet grape soda, and this wasn't quite that. After a few sips, I started to like it more, but it was still far from one of my favorite grape sodas. I'll give this an average score (like I've given to many Yacht Club sodas - they haven't impressed me much).
Score: 5 out of 10.
