Well, I had a similar thought once, but from the opposite direction.
You know how herbal tinctures are alcohol based? I was thinking of doing something with those. I love the way swedish bitters taste! I think they could make a rockin' drink! (Well, they do already. But I'm not gonna drink the whole bottle even though it's tempting! hee hee)
I've had wheatgrass juice with honey in it, it was deeeeeelicious! Add a little extra sumpin-sumpin and BOY would it ever have a kick!
