Was it something you thought you'd love but hated? How about a flavor you thought you'd never like but did? Possibly just something that tasted waaaay different than you thought it would either good/bad/indifferent?
The 2 flavors that surprised me most, and both in a good way, were both semi-homemade.
1) I had put a few Menthol drops (from Juicy) into the wrong vial and accidentally mixed them into Watermelon. I thought it was ruined... till I vaped it. AWESOME!!!
2) I, just to try it, dripped one drop of 555 and one drop of RY4 into my atty and hit it... wow.. WOW... Vapegasm.... Probably the nicest "relaxing with a cognac in a cushy chair" kinda vape I could ask for.
Probably RY4 & 555. By the descriptions, I thought I would hate 555 & love RY4, but it's definitely the other way around. Also Ecopure Rich. Everyone raves about it, but I don't think it tastes like anything.
