I do wish cola was a more common candy flavor in the US. Haribo makes some good cola gummies but they are hard to find in my area. I had never tried G Fresh gummies before, so I picked these up at the Mitsuwa in Arlington Heights, IL during my recent trip.
These gummies seemed more like vitamins than candy. They claimed to be a source of both vitamin C and GABA. I had never heard of GABA before, but a little research told me that it is gamma-aminobutyric acid, a neurotransmitter naturally produced in humans that regulates muscle tone, among other things. I highly doubt the amount in this candy has a measurable effect.
First, let me point out the over-engineering of the bag - the tear slit was located between two ridges to ensure a straight rip. On the candies themselves, the sour powder on the surface almost looked like scales! The gummies smelled like sweet cola candy and were immediately sour on the tongue. I could taste the vitamin C really well. The actual gummy part was mild in flavor, with a slightly sour, syrupy cola taste.
The texture of the gummies was very firm, and almost a little too hard. They were made with agar-agar and not gelatin, but I don't think that was the cause of the firmness. The coating was much more sour than the inside, but overall, it made for a pleasantly tart cola flavor. They were quite addictive!
