I grabbed this at the corner store this past weekend:
Brand: (Mexican) Squirt.
Purchase Place: Marshall Stop, St. Paul, MN.
Review: This had a little more "kick" than the Squirt I'm used to. And I don't think it's all in my head. Squirt that I'm used to is a little smoother, and this isn't. It's sure not bad, but it's just slightly different. Otherwise, the pretty normal citrus flavor I'm used to. (Oh, but COOL bottle. The slight spiral was nice.)
Score: 6 out of 10.
