Whisky or whiskey?
The extra letter tells you something about origin—not quality.
The short answer
Scotland, Canada, Japan and most other producing countries normally write whisky. Ireland and the United States normally write whiskey. Both words describe the same broad family of distilled grain spirits.
Why did the spellings split?
The words share the same linguistic roots. During the nineteenth century, Irish producers increasingly used the spelling whiskey to distinguish their spirit from Scotch whisky. American usage largely followed Irish convention because of immigration and distilling influence.
Are there exceptions?
Yes. Some American brands use whisky and some producers choose a spelling for historical or branding reasons. Follow the spelling printed by the producer when discussing a specific bottle.
