Irish Whiskey is a globally recognised product protected under under EU geographic indications (GIs), but is it defined by where it is distilled, or by where the ingredients come from?

This was at the heart of questions put to Martin Heydon, Minister for Agriculture, Food and the Marine, by Social Democrats TD Jennifer Whitmore recently.

The Wicklow TD asked Minister Heydon about the proportion of grain used in the production of Irish single grain whiskey that is sourced domestically, and the measures in place to support the use of Irish-grown grain in whiskey production.

She also asked the minister whether consideration has been given to strengthening requirements or supports for the use of Irish-grown grain in single grain whiskey production, in the context of protecting the integrity and value of the Irish Whiskey designation.

Minister Heydon said that protecting the integrity and value of the Irish Whiskey designation “is of key importance”.

He added: “This integrity of Irish Whiskey ensures global brand authenticity, justifies premium pricing, and secures jobs across the island.

“In the Irish Whiskey product specification, single grain refers to a whiskey produced at a single distillery using a mash bill that includes grains other than 100% malted barley (such as corn, wheat, or rye), distilled in a continuous column still.

"The term ‘single’ refers to the distillery, meaning the whiskey was produced entirely at one specific location rather than blended with spirits from elsewhere.”

A mash bill (or grain bill) is the specific recipe of grains used to produce a whiskey. It details the exact grains and their proportions (for instance., 75% corn, 21% rye, and 4% barley) that are milled, mixed with hot water, and fermented.

The mash bill is the foundation that dictates the spirit's flavour, texture, and legal classification.

Irish grain

Minister Heydon did not outline any obligations for using Irish cereal for a product to qualify as Irish whiskey.  

He said: “While the proportion of grains used in the production of single grain whiskey in Ireland is a commercial matter for the individual distillers involved in the production of that Irish whiskey subcategory, I am committed to supporting the use of Irish grain in whiskey production.”

A technical file from the Food Industry Development Division of the Department of Agriculture, Food and the Marine does not specify obligations for inclusion of Irish-grown cereals.

Instead, to qualify for the status of Irish whiskey, the product must be distilled in Ireland.

The file says that “Irish Whiskey/ Uisce Beatha Eireannach/ Irish Whisky” is a spirit distilled on the Island of Ireland, including Northern Ireland, from a mash of malted cereals with or without whole grains of other cereals and which has been:

Saccharified by the diastase of malt contained therein, with or without other natural enzymes;
Fermented by the action of yeast;
Distilled at an alcoholic strength of less than 94.8% by volume in such a way that the distillate has an aroma and taste derived from the materials used;
Subject to the maturation of the final distillate for at least three years in wooden casks, such as oak, not exceeding 700L capacity.

Minister Heydon said that he continues to support new market development and market access efforts “for our quality, sustainable food and drink products, including Irish whiskey”.

He added: “My department has also funded equipment in the National Brewing and Distilling Centre in Teagasc, Oakpark in Carlow.

"This facility allows producers to develop and innovate new products to meet consumer demands and tastes in the global market.”

Consultation

A public consultation on reviewing the technical file for Irish Whiskey, which sets out how it can be produced, opened on Friday (June 26).

The review of the technical file may result in changes to the rules on how Irish Whiskey is produced.

While the Irish Whiskey Technical File does not currently require the use of Irish grain in the production of Irish whiskey, the review offers the opportunity to change that.
