Irish whiskey: an introduction
The last few years have seen an exciting renaissance in Irish whiskey, with distilleries old and new producing some of the world’s best spirits. From just four to more than 30 and counting in the space of 10 years, if the boom in new distilleries is anything to go by, then the Irish whiskey category is coming back stronger and better than ever.
With new brands coming to market every month, it can be difficult to know exactly who is nailing it and what you should even be looking for when it comes to choosing the right bottle from the Emerald Isle.
What you need to know
All Irish whiskey must be aged for a minimum of three years in wooden barrels such as oak in Ireland (including Northern Ireland). There are currently four spirit categories in Irish whiskey:
Single malt: made by one distillery, distilling 100% malted barley in a pot still. Typically giving notes of toasted oak, biscuits and malt chocolate.
Single grain: made by one distillery, distilling no more than 30% malted barley with the majority unmalted cereals (typically corn, wheat or barley) and distilled in a column still. This style usually gives light floral notes of sweet grain and honey.
Single pot still: made by one distillery, distilled from a minimum of 30% malted barley and a minimum of 30% unmalted barley with up to 5% cereals added. This is classed as the most traditional style of Irish whiskey. It’s classically a heavier style with flavours that can range from baking spices and vanilla to rich Christmas cake.
Blended: a combination of two or more styles of Irish whiskey blended together. A very exciting classification of whiskey which allows brands space to create stunning blends.
As Irish whiskey is not strictly held to maturing in oak casks, there has been a huge surge in exciting cask ageing outside of the whiskey norm. Another point to keep in mind is that while a lot of brands will triple distil their whisky, it is not a legal requirement, and is instead a style that adds to the adventurous nature of the category.

Best Irish whiskey to buy
A favourite of newbies and connoisseurs alike, Green Spot is a seven to 10-year-old whiskey boasting an elegant and rich body with notes of baking spices, crisp green apples and chewy toffee, showcasing the single-pot-still category very well. It’s also a great whiskey for an old fashioned, making a beautiful sweet and balanced cocktail.
A corn-heavy triple-distilled Irish whiskey aged exclusively in French oak ex-cabernet sauvignon casks from California, expect sweet marmalade flavours and a dry red wine finish. Made for a highball drink on a hot summer’s day.
From the skilled brewing and distilling Lyons family, The Original is a Dublin blend of malt and grain whiskey with smooth notes of vanilla, caramel and oak. Part of this whiskey has been distilled in their stunning St. James’s Church distillery.
Whiskey bonding refers to the practice of sourcing spirit from other distilleries to be matured, blended and bottled. Once widespread in Ireland, the art of bonding had all but died out until a few years ago, when it made a comeback thanks to modern whiskey bonder J.J Corry.
From a 400-bottle second batch, The Flintlock showcases J.J. Corry’s blending and bonding skill, having created what is effectively an alcoholic vanilla ice cream with helpings of luscious syrupy pear notes and a long finish. Enjoy as a treat to kick off a bank holiday weekend in style.
