1410 - Drinky MacDrunkard discovered how to make single malt scotch. He was then beaten to death by his neighbors when they found out they had to wait 12 years before they could drink it...

HAHAHA

That reminds me of the time I brewed up a barleywine (ala Thomas Hardy) with a friend of mine who wanted to shove the racking tube down my throat when I told him he had to come over in a year's time to try it out and see if it was ready for consumption.
