Whisky

Whiskey with an e is Irish or American. Whisky without it is Scotch, Japanese and Welsh. Both are correct, and the spelling tells you where the bottle is from before you read the label.

Everything else in the category follows from three things: the grain, the cask, and how long it sat there.

What whisky actually is

Mash the grain, ferment it, distil it, put it in oak and wait. That is the whole process. What separates one bottle from another is which grain, which cask, and how many years.

The oak is not optional. Scotch and Irish whiskey both require a minimum of three years in cask. Bourbon has no minimum age but must go into new charred oak, which is why it picks up colour and vanilla faster than anything matured in a refill cask.

The spelling, settled

Ireland and the United States write whiskey. Scotland, Japan, Canada and Wales write whisky. The convention is regional habit that hardened into house style, and both spellings are correct for their own country.

It is worth knowing because it is a reliable signal rather than a piece of trivia: the spelling on a label tells you roughly where the bottle is from before you have read anything else on it.

The styles, one line each

Scotch. Made in Scotland, matured at least three years in oak. Ranges from delicate and floral to heavily peated depending on region and cask.

Irish whiskey. Matured at least three years. Generally lighter and softer than Scotch, often triple distilled.

Bourbon. American, at least 51% corn, matured in new charred oak. Sweeter and rounder, with vanilla from the fresh wood.

Rye whiskey. American, at least 51% rye. Drier and spicier than bourbon, which is why classic cocktails often specify it.

Japanese whisky. Distilling began in the 1920s, using Scotch methods and often Scottish-trained distillers.

Canadian whisky. Matured at least three years. Widely called rye in Canada regardless of how much rye is actually in it.

Welsh whisky. The smallest of the group and the newest.

Which to reach for

For a highball, use something light and unpeated. Peat and soda rarely help each other, and the smoke ends up sitting on top of the drink rather than in it.

For a stirred drink, rye is the reliable choice. The spice holds up against sweet vermouth where a softer whisky disappears into it entirely, which is why so many pre-Prohibition recipes specify it.

For sipping, the choice is yours and nobody else’s.
