So... Thanks to all that replied to my thread.
Recieved the koolada last night, added some (too much to start off) to a 10ml bottle of Ninja Fruit - Sensai Ice.
Had to make some slight adjustments by adding more stock liquid etc and believe I've got a ratio now for going forward that works. But oh my god, does this increase the flavour profile 10 fold.
I reckon koolada is going to be a common addition to all my stock bought juices now!
So again, thanks for your help!!
