Finally got around to mixing this one. Fascinating. You can just about pick out the grape and cactus, but in combination it is a totally unique and otherworldly flavour. Just when you think you've got it, you get a different note slapping you in the face. It's somewhere in between purple candy, a fruity burst, and a strange unfamiliar turkish delight flavour.
It'll definitely take me until the end of the 50ml to come to a firm conclusion on it, but it's certainly a powerful, refreshing flavour without being offensive. Great contrast when your tastebuds are exhausted with endless custards and vanillas.
