Which is the correct spelling whisky or whiskey? It’s the topic many a whisky-lover gets worked up about. And more to the point, does it really matter? Unfortunately, it isn’t a simple yes or no answer – both spellings are correct!

The introduction of a new spelling – for the Irish distillers

Until the late 19th Century, all whisky distilleries spelt whisky without the ‘e’. At the time Irish distilleries were supplying about 70% of the world’s whisky. But with the 1860s Spirits Act being passed by the Gladstone government, Irish whiskey distillers needed a way to differentiate their whiskey from those of the Scottish distillers – and so the ‘e’ was introduced into the Irish distiller’s labels.

America followed suit – but not everyone agreed

The Irish Whiskey distillers initially supplied 70% of the world’s whisky. However, when they first started promoting their whiskey to the American market in the 1800s, they decided to start the ‘with an e’ option, to help differentiate their whiskey from the new Scottish versions that were starting to take hold. The American distilleries soon adopted this spelling of whiskey and it became the norm across America.
Canada, India and Japan preferred to follow the Scotch whisky labelling, opting to omit the ‘e’. For Japan, in particular, this decision was taken to pay homage to its Scottish cousin.

It isn’t just the spelling that makes the whisky different

However, there is more than a spelling difference between the two. Primarily the main difference between the three main scotch producing countries includes their choice of grain, the stills used, along with the distillation process itself. Here’s how that breaks down:

Grain use

One of the biggest difference is in the use of grain. Scottish distillers prefer to use malted barley as their grain of choice. However, Irish whiskey is often produced with barley, but it’s often a mixture of malted and unmalted barley, whilst the American distillers often use various grains, including corn, rye or wheat.

The stills

Irish and American whiskey is often produced in large, round-bottomed pot stills. Scottish whisky distillers will often stick with the more traditional smaller pot stills.

The distillation process

As a general rule of thumb, Irish Whiskey is distilled three times. American whiskey and its Scottish counterparts both prefer to distill theirs twice.

The use of peat

Generally, the use of peat is limited to Scotch whisky. Peat is used to dry the malted barley, making it ready for milling and mashing. It is the peat that gives Scotch whisky its full-flavoured smokiness. Irish and American whiskey has less of a smoky taste, as they prefer to use wood or other fuels during this process.

The different whisky options

Finally, it’s not just the countries and their processes that dictate your whisky choices – there’s also the different blends to consider! Here’s a brief breakdown of how they differ:

• • Malted barley is achieved when the grain that has been soaked, allowing it to start germinating or sprouting. This process starts to turn the starch into sugars.
    Single-malt whisky is 100% malted barley and made by one distiller.
  • Blended malt whisky is still 100% malted barley, but it is created using a blend of whiskies from two or three distilleries.
  • Blended whisky is created when single-malt whisky is mixed with either a corn or wheat whisky.
  • Single-grain whisky is 100% corn or wheat whisky. Usually made for blending.

No matter what the country of origin, the distillation process used or the blending options, whisky still seems to be one of the world’s most popular drinks.

And let’s not forget, you can also have it neat with ice, add a dash of water, or even use it as a mixer!
