For generations, whiskey fans have repeated one simple rule: Ireland and America spell whiskey with an "e," while Scotland, Canada, and Japan spell whisky without one. But where did that rule actually come from—and does this formula hold up historically?

Today I'll revisit one of the show's earliest topics to dive deeper, separate fact from fiction and uncover the surprising history behind one of whiskey's most debated letters. Along the way, we'll see what the government and the Father of American English, Noah Webster, has to say. I'll look at the cultural confusion of regional language differences, and the myths that have grown around the spelling of whiskey itself.

Was the "e" really invented by Irish distillers in the 1800s to distinguish their spirit from Scotch blends? Did Scotland always reject the spelling whiskey? And have Americans always embraced whiskey with an e?

Using newspaper archives spanning England, Scotland, Ireland, and the United States, I'll traces how the spellings evolved from the early 1700s through Prohibition and into the modern craft whiskey era. The results challenge many of the stories commonly repeated in whiskey circles today.
