Uh-Oh

I remember that when I was a kid, I got a taste of some mildly alcoholic root beer that my dad was making, and it tasted so bad to me that even now as an adult I still don't like the flavor of alcohol. So you might figure that the same thing would work with the kids. But the only problem is that when they tasted it, they liked it. Now what. (Don't worry, nobody let them drink any).
