funny as I am not into grape flavor (drinks, gum, hard candy, Popsicles, et al), someone sent me some grape LorAnn (flavor drops) and I will be sorry to see it go. Good combination I have been using has been having it mixed with a bubble gum flavor, or the grape and strawberry (another flavor I don't like the taste of in other things) with a few drops of menthol.
Remember that pizza juice might seem like a good flavor.... but vaping it is another matter (I am still somewhat green around the gills from trying it)
