In general their flavors have a wide range when it comes to concentration. Where the same kind of flavor from a different flavor company would go into the nasty/chemically/floral range if you used too much in general Capellas flavors don't tend to go into that "icky" range very easy. Not sure why, much have something to do with the composition. maybe its why you generally pay a little more for Capellas than the other flavor companies. I use them all though. Capellas, TPA/TFA, Flavor Art, Flavor West, Super Concentrates.. ertc. There are just flavors that other companies don't have. I like to mix and match.
