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. Try our recipe for Irish coffee here.

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.
