I opened this up with lunch today:
Brand: Virgil's Zero Root Beer
Origin: Los Angeles, CA.
Purchase Place: Kowalski's, St. Paul, MN.
Review: This had a deep flavor, but slightly too much anise (which is what I thought of their regular root beer too). I wasn't a fan. Even though it had a deep flavor, it was still weak. There was an odd berry flavor in there that was OK (and unexpected - maybe the Stevia?), but that the was most this had to offer. Giving it an average score.
Score: 5 out of 10.
