Review of Sour Blue Raspberry Flavor-WF:

It reminds me of FW Hard Candy, but without the harshness or negative aspects I get from Hard Candy, and more "blue" flavor. After even just 1 day the flavor starts becoming more pronounced, but to me it's not exactly like blue raspberry jolly rancher. I think it tastes like what the picture shows, but without the sour part. I get no sour at the 6% nor 8% that I've tried.  I've been making it at 8% with 1.6% tfa sweet & tart and it's very good.
I also added some to the "blue raspberry jolly rancher" I usually make, and it made the juice taste closer to an actual blue raspberry jolly rancher. That recipe is on reddit, and Bullcity has all the ingredients.
I'll definitely be getting more my next order.
