The difference between whisky and whiskey

In short:

The distinction between whisky and whiskey is a common question that often piques curiosity. In this article we’ll explore exactly what sets them apart.

To ‘e’ or not to ‘e’? You’ll likely have seen it spelled as whisky and whiskey – and it’s often difficult to know which spelling to use. They both sound the same, but do they mean the same thing? First, let’s take a look at the basics of making whisky.

How is whisky made?

Whisky production involves several key steps. First, grains like barley, corn, rye, or wheat are ground and mixed with hot water to extract vital sugars. This mixture, known as 'the mash,' undergoes fermentation where yeast is added to convert sugars into alcohol. The resulting liquid, called ‘the wash’, is then distilled in copper stills to separate alcohol from impurities, creating a clear spirit.

The spirit is aged in wooden barrels, typically oak, which imparts flavour and character over time. Whisky maturation can take years, allowing the spirit to develop complex aromas, flavours, and texture. Finally, the aged whisky is often diluted with water, filtered, and bottled for enthusiasts to enjoy.

What's the difference between whisky and whiskey?

To put it simply, ‘whiskey’ is the term used for Irish and American spirits, whereas ‘whisky’ is used in Scotland, Japan, and Canada.

The earliest written evidence of whisky production is found in Scotland, dating back over 500 years ago. Scottish whisky, or Scotch, is never referred to as whiskey. For a whisky to be labelled Scotch, it must be produced and matured in Scotland. Once produced, Scotch whisky must be matured in oak for at least three years before bottling. Peated whisky, often produced in Islay, derives its smoky flavour from compounds released by peat fires used to dry malted barley.

Inspired by Scottish whisky-making traditions, Japanese distilleries have adopted the same naming convention. They have developed their own unique approaches, incorporating meticulous attention to detail and craftsmanship. Japanese whisky is renowned for its exceptional quality, smoothness, and complex flavours, often showcasing a delicate balance between tradition and innovation.

Distillation is said to have been present in Ireland as early as 432 AD, but the word whisky itself is derived from Gaelic. Many believe that the 'e' in whiskey was added by the Irish to differentiate their product from the Scottish one, and it has remained as whiskey to this day.

Irish whiskey shares some similarities with Scottish whisky, but there are key differences. Like Scottish whisky, Irish whiskey must legally be matured for three years before release. However, Irish whiskey uses little or no peat, in contrast to some famous Scottish whisky producers.

Over the centuries, Ireland has consistently retained the name whiskey for its beloved spirit. However, you may have noticed that distillers in the United States also use the term ‘whiskey’.This can be attributed to the significant influx of Irish immigrants to the United States, who brought their distillation methods and techniques with them, thus shaping the American whiskey tradition.

American whiskey has gained recognition for its wide range of styles and distinctive characteristics. One of the most renowned types is bourbon, primarily crafted from corn and aged in freshly charred oak barrels. Bourbon is celebrated for its rich and sometimes spicy flavour profile, along with a rounded sweetness. Another popular style of American whiskey is rye whiskey, made from rye grain, which typically has a spicier and drier flavour profile compared to bourbon.
