Review of Boysenberry-Raspberry Flavor-SC-WF:

I love this to accent a blue raspberry or a cotton Candy. It has the right amount of sweet. I get a tart note
Accent.5-1.25%
Background 1.5-2%
Main 2-3% 

nice tart blend of dark berry and ripe red raspberry, juicy, sweet, no off notes, lingers on my pallet. This is a great accent flavor.
