🥃 Irish Grain Whiskey
Irish whiskey from column stills: no more than 30% malt, the rest maize, wheat or barley; lighter in taste, the backbone of blends.
Irish Grain Whiskey (Grain Irish Whiskey, also Irish Grain Whiskey) is a kind of Irish whiskey made from malted barley (no more than 30%) and whole unmalted cereals, usually maize, wheat or barley, distilled only in column stills. It is matured for at least three years in wooden casks on the island of Ireland.
According to the technical file of the Irish Whiskey geographical indication (2014), the grain is milled into flour, mixed with water and cooked so that the starch softens and becomes available to enzymes. The mash is then cooled and malt is added, whose enzymes turn the starch into sugar. The fermented mash, usually not separated from its solids, is distilled continuously in columns.
Most Irish grain whiskey is now distilled three times, although each distillery chooses its own scheme. The spirit comes off at about 94% ABV and is reduced with local water, usually to 63–70% ABV, before being filled into casks. The character, from very light to fuller, depends on the point at which the spirit and side streams are taken, but overall grain spirit is far less intense than that from pot stills.
The continuous still was patented in 1830 by Aeneas Coffey, a former Inspector General of Excise in Ireland. Irish distilleries adopted it widely only at the end of the 19th century, when large plants appeared in Belfast, Dundalk and Derry. It was light grain whiskey that gave blenders the base for Irish blends. “Single Grain” means that all the whiskey was distilled at one distillery.
Why it matters to you. Grain whiskey is lighter in taste than malt or pot still, but it is not unmatured spirit: the rules are the same, at least three years in casks and 40% ABV or more. Blenders mostly use it as a light base for the blend. The only permitted colouring is caramel E150a. The WHO reminds us that there is no safe dose of alcohol.

Frequently asked questions
Which cereals is Irish grain whiskey made from?
From malted barley, no more than 30%, and whole unmalted cereals, usually maize, wheat or barley. The malt is needed so that its enzymes turn the starch into sugar.
Is it true that grain whiskey is just unmatured neutral spirit?
No. It is distilled below 94.8% ABV to keep the aroma of the raw material and matured for at least three years in wooden casks. The taste is lighter than whiskey from pot stills, but it is a full whiskey of 40% ABV or more.
How many times is Irish grain whiskey distilled?
Most is distilled three times in a system of two or three columns, but each distillery chooses the number of distillations. No apparatus other than column stills is permitted for grain whiskey.
At what strength is the spirit filled into casks?
The spirit leaves the column at about 94% ABV. It is reduced with local water, usually to 63–70% ABV, and only then filled into casks.
Who invented the column still?
Aeneas Coffey, a former Inspector General of Excise in Ireland, patented the continuous still in 1830. At the end of the 19th century the Scottish industry also adopted it widely.
