Review of Graham Cracker V2 Flavor-Cap:

I just tried this at 1.5% and it tastes exactly like a graham cracker! Identical! 
I then mixed it with Capella Cake Batter (50/50) at 1.5% and it's amazing! The graham cracker is still very much apparent, but is now more like a dessert rather than a snack. 
Spot on Graham Cracker IMO. I have virtually all of the graham cracker flavorings, and this one is now #1
