Diketone-free. Very peachy on the front end with a mixed-melon exhale. Highly recommend the sour in this one as I always do; the small percentage is used as an enhancer more than a sour component. 1-2% Koolada optional. I personally love fruit vapes with Kool. TFA Honeydew II @ 2% can be subbed for the CAP Honeydew, and the Watermelon is easy to sub too. I would not recommend switching the Yellow Peach as that is an unusually tart peach flavoring, but I am sure TFA Juicy Peach (or something else) would also make a pleasing vape... just will be very different. Peachy Melons 8% CAP Yellow Peach 3% CAP Honeydew Melon 3% CAP Sweet Watermelon 1% TFA Sour (optional 1-2% TFA Koolada) Total: 15-17% Enjoy!
