Irish Poitín: Ireland's Protected Traditional Spirit
In March 1997, poitín became legal on the Irish home market after a period of illegality stretching back to 1661. Today, “Irish Poteen/Irish Poitín” is a protected name covering the whole island of Ireland, including Northern Ireland, with specific rules for production, verification and labelling. Its ingredients can include cereals, whey, sugar beet molasses and potatoes: this is far more than another name for potato spirit.[1]
What Irish poitín’s protected name means
The small pot still gave poitín its name. “Poitín” comes from the Irish word pota, meaning pot, after the still traditionally used to make it. Both “IRISH POTEEN” and “IRISH POITÍN” are now permitted forms of the geographical indication, or GI. The technical file defines an all-Ireland GI, covering spirits distilled across the island, not just within the Republic of Ireland.[1]
Its formal category is “Other spirit drink”, not Irish whiskey. Poitín has its own specification, so the rules for one Irish spirit should not be carried across to the other. The separate Irish whiskey specification governs a different protected name.[1]
A GI ties a name to a defined place and a specification, rather than simply to a producer’s address. For poitín, that specification controls ingredients, production, permitted treatments and presentation. The distinction between protecting a name and defining a spirit category is explored in geographical indications.[1][9]
How protection and verification fit together
The specification sets the requirements; verification checks that producers meet them; GI protection controls who may use the name. These three functions work together to protect Irish Poteen/Irish Poitín.[1][2][9]
The name was listed in Annex III to Regulation (EC) No 110/2008. The European Commission services registered the current technical file on 27 March 2019. The UK register records it as a GI from before 2021, registered under the UK scheme on 31 December 2020 at 23:00.[1][2][3]
Revenue verifies compliance in Ireland, while HMRC does so in Northern Ireland. Revenue’s verification manual, last reviewed in September 2026, names Regulation (EU) 2019/787, Commission Delegated Regulation (EU) 2021/1235 and Ireland’s European Communities (Spirit Drinks) Regulations 2015, S.I. No. 316 of 2015, as its legal framework.[2]

The broader framework for spirit categories and their presentation is covered in EU spirit drink rules.[1][2][9]
Ingredients and distillation
Barley and malted barley are poitín’s most common cereals, but its traditional ingredients reach well beyond grain. The technical file lists cereals, grain, whey, sugar beet molasses and potatoes. There is no single recipe that every producer must follow, and potatoes are only one possible starting point.[1]
At least 50% of the traditional ingredients must come from Ireland. Revenue’s verification manual frames its check as whether at least 50% of the mash ingredients were grown in Ireland. Where the ingredients come from matters alongside where the spirit is distilled: both form part of verification.[1][2]
The normal maximum distillation strength is 94.7% ABV. An exception covers products made continuously since 1997 that were traditionally distilled above that strength, allowing them to continue to be sold as Irish Poteen/Irish Poitín. It does not open the higher limit to new products.[1]
Small pot stills feature in the traditional production account, while the technical file also records more recent use of hybrid and column stills. The equipment alone therefore cannot tell you whether a spirit qualifies for the name. Later treatments such as activated charcoal filtration are not allowed.[1]
Strength and permitted flavouring
Since 1997, the minimum strength has been 40% ABV, with some products reaching 90% ABV. Products above 70% ABV need extra label information warning consumers of their strength. Those figures describe the specification and its range, not a reason to choose a stronger product.[1]
The technical file also limits methanol to 30 grams per hectolitre of 100% volume alcohol. This is a compositional requirement expressed against pure alcohol, rather than a figure for the volume of the finished bottle.[1]
Poitín need not be entirely unflavoured. Macerations and infusions with native Irish ingredients are permitted up to 10% of the product. The technical file’s examples range from apple, pear and blueberries to mint, wildflower bogbean and ginger.[1]
Flavourings must be consistent with native Irish ingredients and natural plant materials. Commercially made flavourings that meet this condition may come from outside Ireland. Their origin is governed separately from the requirement for an Irish share of the traditional production ingredients.[1]
The narrow permission for wood storage
A poitín made from two cereals alone cannot qualify for wood storage. The recipe must use at least two of the listed raw materials, and at least one must not be a cereal. Spirit meeting those conditions may be held in wooden casks for no more than 10 weeks.[1]
Even then, the language is tightly controlled. The rear label must state “Stored/held in wood for .... weeks”. The product must not refer to casks, maturation or ageing anywhere in its labelling or marketing. Permission to use wood is not permission to present the spirit as aged.[1]
When checking a bottle, look for the required statement of weeks held in wood, rather than an ageing claim. “Aged poitín” is not an interchangeable description for this treatment. The 10 weeks limit also applies only to qualifying recipes, not to every poitín a producer might make.[1]
How production is verified
Revenue’s verification follows the spirit through four stages in Ireland: brewing, fermentation, distillation, and bottling and labelling. All four must take place in an appropriately authorised tax warehouse. Brewing, fermentation and distillation must happen at one premises; bottling and labelling may be contracted to another facility authorised by Revenue.[2]
The technical file separately allows bottling outside Ireland, with the spirit shipped in inert bulk containers. A bottling address therefore need not be the place of distillation. The all-Ireland origin requirement governs production of the protected spirit, rather than requiring every bottle to be filled on the island.[1]
Producers must apply annually for verification of each stage, and verification visits are subject to EU audit. The consequence of failure is direct: Revenue’s manual states that if any stage fails, the product “cannot legally be marketed as Irish Poteen”. Since 29 January 2016, anyone producing and marketing Irish Poteen has been required to follow the technical file.[2]
Verification thus reaches beyond the finished liquid to the production stages and their authorised locations. Being clear in appearance and distilled somewhere in Ireland is not enough for a spirit to earn the protected name. It must meet the specification and the relevant verification requirements.[1][2]
What the label must say
Look first for the protected name on the front of the bottle. Each word must have equal prominence, and the GI must not be overlaid or used with other words. The phonetic spelling “Irish Potcheen” may appear alongside the protected name, but cannot replace it.[1]
In the EU, Regulation (EU) 2019/787, Article 15(1), says geographical indications must not be translated on labels. Article 10(7) also bars use of a GI for a drink that does not comply, even with expressions such as “like”, “type” or “style”. Those qualifiers cannot turn the protected name into a description available to other products.[9]
After identifying the name, check the stated strength and any wood storage information. Each tells you something different: the spirit’s protected identity, its strength, or a permitted treatment. These label requirements sit alongside production verification; they do not replace it.[1][2]
Common misunderstandings
“Illegal moonshine” describes poitín’s history better than its present. The technical file records a long period of illegality, from 1661 to 1997. Yet poitín has been legal on the Irish home market since March 1997, and the protected name is registered in both the EU and UK systems.[1][3]
Nor must poitín be made from potatoes or bottled close to 90% ABV. Its permitted ingredients are much broader, and the minimum strength is 40% ABV. Another important distinction is geographical: Northern Irish production sits within the GI, with HMRC responsible for verification there. The protected spirit belongs to the whole island.[1][2]
