Whisky is fun to drink! I wonder what it's made from. Do you know?
Yes, I certainly do!  It is made from a fermented grain mash that is distilled.
Fermented grain mash? What is that?
It is when various grains, such as barley or corn, are mixed with water and sugars and allowed to come in to contact with yeast.  As it rots, it releases alcohol.
Oh, I see! That's weird! You wouldn't happen to know when whiskey was invented, would you?
I am not sure, but distilled spirits have been around since at least the time of Rome (they called it "aqua vitae").
