Irish whiskey is made from a high grain mash of barley, wheat, and corn. The exact quantities of each grain depend on the type of whiskey. The most common primary grain is barley.  The barley and be malted, un-malted, or a combination of each.

Basic Requirements for Irish Whiskey

The Irish Whiskey Act of 1980 defines the basic requirements for Irish whiskey. The act protects Irish whiskey by statute law and provides regulations and labeling for the spirit. The requirements include:
– Produced and aged in Ireland.
– Made from cereal grains that are fermented with yeast.
– Distilled no higher than 94.8% ABV (proof of 189.6).
– Aged in wooden casks for a minimum of three years.
– Free of added substances with the exception of water and caramel coloring.
– Bottled at a minimum ABV of 40% (proof of 80).

Types of Irish Whiskey

Malt Irish Whiskey: Made in pot stills at one distillery with only water and malted barley. Example – Bushmills 10-year-old, 80 proof.

Pot Still Irish Whiskey: Denotes it was made from malted and un-malted barley and distilled only in a pot still. Example – Redbreast 12-year-old, 80 proof.

Grain Irish Whiskey: It was made from un-malted grains in a column still. Example – Teeling Single Grain, 92 proof.

Blended Irish Whiskey: Indicates the whiskey is a blend from both column and pot stills. Example – Jameson, 80 proof.

Irish Whiskey Taste Profile

Irish Whiskey has a distinct flavor profile that can be described as light, fruity, and floral, with common notes of cereal grains, vanilla, caramel, and oak.

Single Malt Irish Whiskey often has a fruity profile with notes of apple, pear, and citrus, and a subtle nuttiness and hint of vanilla. Those made of 100% malted barley-based blends are smooth, sweet, and malty. 

Blended Irish Whiskey is generally smooth, with notes of caramel, vanilla, light spice, and a hint of oak. 

Like other spirits, the flavor profile can depend on where it was produced, how it was aged, and brand desires for its signature taste profile.

With St. Patrick’s Day around the corner, many will be sipping and toasting with an Irish Whiskey. I hope that this basic overview will help you to enjoy it all the more!
