The other 3 Frostie sodas I've had earned scores of 6, 6, and 6.5. I was hoping this would be decent as well:
Brand: Frostie Concord Grape Soda.
Origin: Detroit, MI.
Purchase Place: Frattallones Ace Hardware, St. Paul, MN.
Sweetener: High Fructose Corn Syrup.
Review: This smelled strongly of grape once I twisted off the top. And the first sip didn't disappoint. This was a deeply flavored grape soda. Classic. The long-lasting aftertaste was fantastic, but the only weird flavor was a little bit of an odd sharpness immediately after taking a sip. But that went away right away. It's probably not in my top-5 grape sodas of all time, but it's close.
Score: 8 out of 10.
