It was so simple all you had to do was put water yeast and barley together for a few days. Drain off the fluid and fun it through a huge copper space rocket with a bend at the top. At a very high temperature. Then do it again and in some instances do it again.
Then when that has happened don't drink it. Put it in a wooden oak barrel for several years, the longer the better. And magic you had created whisky. I don't know why it wasn't thought of earlier its so basic. People are doing things like it all the time.
It's like a good quality sausage who would of thought of killing a pig, mincing up all that stuff putting it in a stomach lining, chucking it on the bbq and you have a bit more magic. And how about inventing Dijon mustard to go with it, how did that happen.
My vote goes to the sausage.
