Soft drinks are very acidic. When I was a child, I remember my parents using Coke to clean out a radiator.

When you make lemonade, you add lemon not just for the flavor. Even Kool-Aid has acid.

Make up some sugar water. Ten percent sugar is about what Kool-Aid is. Taste it. See how much you like it. Then add some lemon juice and do the same thing.

It wasn't until (Louis) Pasteur that we knew how wine was made. Prior to that, it was like magic. In low-acid situations, you'd stick your nose in it and it would be disgusting.

More sugar will make it taste less acid.

[It denied as] ridiculous ... he does not take alcoholic drinks.
