Review of Sour Blue Raspberry Flavor-WF:

Read reviews and was skeptical. I’ve tried a few different blue raz flavors and either they taste like soap, are very floral or harsh like it’s suspended in alcohol. 
After a few small 10ml tester bottles I figured out what worked for me. 4.5% flavoring and 1% capella super sweet. 

The sweetener rounds out the flavor, it doesn’t taste like soap at all. The sour aspect isn’t really there, by far the best blue raz flavor I’ve tried in the past 10 years. 

Only regret I have is not buying a bigger bottle, next time I’ll be getting the 4oz bottle of it
