Interesting observation. Well, for me, anyway.
I had some juices at 0.4% menthol. For my taste preference, that's pretty strong damn menthol right there. On a whim, I decided to use my other menthol "base" which is 0.5% menthol + 0.5% koolada. MUCH more mellow.
So the menthol went up, but still ended up being more mellow. Only explanation I have is that the Koolada tones it down. But I can't figure out why that is, if both have the cooling effect as a main property.
