mix the jak with the cherry juice,after blending put them in a high glass , then put the grape juice so that it dosen't blend with the jak and cherry. once you are done put some vanilla on top (i use sticks of vanilla but you can use essence)
it's verry easy to do, the vanilla gives it 'something' that makes it a pleasure to drink, try it! the best thing is that you won't get drunk from it.
