Review of Butterscotch Flavor-FA:

Very good, just not exactly the flavor that came to mind when I ordered it. Works very well with Kahlua and Irish Cream, works nicely in a lot of recipes. Not too sure about using it as a stand alone flavor, although I suppose it wouldn't be too bad. 
As always, Bull City is the best place to find these, and they have the best selection of flavors. Super fast shipping and the customer service is BEYOND top notch. No better place to buy your supplies from.
