Single Pot Still vs Single Malt Irish Whiskey

Spice and a creamy texture: the Irish whiskey technical file links both to unmalted barley, the grain that sets single pot still Irish whiskey apart from single malt. Single pot still uses malted and unmalted barley together; single malt uses only malted barley. Both are distilled in pot stills. And in both names, “single” means one distillery, not one still or one batch. The defining difference begins with the grain recipe. [1][2]

Single pot still vs single malt Irish whiskey at a glance

These are distinct Irish whiskey varieties, even though they share the same main distillation equipment. This comparison follows the technical file and Revenue’s verification scheme supplied in the site’s November 2026 research record. [1][2]

The grain recipe is the dividing line

A mash bill is a whiskey’s grain recipe. For pot still Irish whiskey, the technical file requires at least 30% malted barley and at least 30% unmalted barley, with up to 5% other cereals such as oats and rye. Within those boundaries, producers have room to choose their own proportions. [1]

Teeling’s Single Pot Still, for example, uses a declared recipe of 50% malted barley and 50% unmalted barley. That equal split belongs to the named whiskey; it is not a requirement for the category. [3]

Malt Irish whiskey starts with 100% malted barley, alongside water and yeast. Distilling it in pot stills does not turn it into pot still Irish whiskey. Without the required unmalted barley, it remains a different variety. [1]

Enzymes do not draw the dividing line either. The technical file allows the malt’s own enzymes “with or without other natural enzymes” for both varieties. Revenue also specifically checks that synthetic enzymes have not been used in pot still whiskey production. [1][2]

What “single” tells you

Revenue permits “single” for both varieties only when all the whiskey was distilled entirely at one distillery and comes from one variety. Neither name counts physical stills, and “single malt” does not mean one distillation. [2]

Read each name in two parts. “Single” identifies the distillery boundary; “pot still” or “malt” identifies the variety and its production requirements. The words do different jobs. [1][2]

Both varieties use pot stills, so looking at the equipment alone will not tell you which category is in the glass. For the broader equipment comparison, see pot stills and column stills.

Both use pot stills, and neither must be triple distilled

Triple distillation is traditional for pot still Irish whiskey, but it is not compulsory. The technical file expressly allows double distillation too. Malt Irish whiskey may also be double or triple distilled, depending on the distillery’s tradition, and Revenue’s verification scheme recognises both approaches for both varieties. [1][2]

The technical file describes both as batch distilled: pot still Irish whiskey usually in large pot stills, malt Irish whiskey usually in smaller ones. These describe established practice, rather than a published still-size threshold that separates the categories. [1]

Bushmills says its single malt is made from 100% malted barley in copper pot stills and is triple distilled. Teeling also describes both its Single Pot Still and Single Malt as triple distilled. Counting distillations will not distinguish the two styles. [3][4][6]

Revenue allows one limited use of columns: residues from pot still distillation may be redistilled in them, provided the resulting feints return to a pot still. Its checks restrict the column to that role. Neither variety thereby becomes a column-distilled whiskey. [2]

What the recipe can mean for flavour

The technical file attributes pot still Irish whiskey’s distinctive spicy flavour and creamy mouthfeel to unmalted barley. These are useful starting points for exploring the category, not a promise that every bottle will show the same spice or the same weight of texture. [1]

Malted barley has its own character. The file associates malt Irish whiskey with fruity, floral and malty character, alongside a full, oily texture and a malty, sweet taste. Single malt is not automatically the lighter-textured choice. [1]

Nor is this a simple contest between spice and sweetness. The file describes traditional triple-distilled pot still spirit as light in aroma and particularly sweet in taste. The more useful contrast is between unmalted-barley spice and creaminess, and the fruit, flowers and malt character described for malt whiskey. Those descriptions overlap as well as differ. [1]

Casks shape both varieties. The technical file names casks previously used for Madeira, Sherry, Port and Bourbon for each, rather than reserving particular previous contents for one style. To explore maturation separately from the grain recipe, read sherry casks and bourbon casks. [1]

Two producer examples make the distinction concrete

Spice appears in Teeling’s notes for both its Single Pot Still and its Single Malt. The two whiskeys also share several production details: both are described as triple distilled, bottled at 46% ABV and non-chill filtered. Their grain recipes differ, as do their cask treatments. Together they make the categories tangible, though the different maturation choices mean they are not a controlled comparison of malted and unmalted barley. [3][4]

Teeling Single Pot Still

Equal proportions of malted and unmalted barley form the recipe, with maturation in American virgin oak, bourbon and sherry casks. Teeling’s tasting notes name cinnamon, grapefruit, cream soda and roasted almonds on the nose, white pepper on the palate, and a dry finish with lingering spice. [3]

These producer notes give a specific expression of the spicy character described in the technical file. The cinnamon and white pepper belong to Teeling’s account of this whiskey, rather than a tasting by this site or a flavour checklist for every single pot still. [1][3]

Teeling Single Malt

Teeling describes its Single Malt as made from 100% malted barley, with finishing casks including ruby port, white port, Madeira and bourbon. Its notes describe tropical fruits, oak spice and ginger on the nose, followed by chocolate, mixed berries and orchard fruits on the palate. [4]

Spice appears here too. The examples show why grain recipes are a starting point for understanding flavour, not its sole explanation: Teeling also describes different cask treatments for these two whiskeys. [3][4]

Peat needs a separate question

Irish single malt can be peated. The technical file expressly permits peated or unpeated malted barley, and Connemara’s producer describes its peated single malt in terms of sweet barley, peat smoke, kippers and baked apple crumble. Those flavours come from the producer’s tasting notes. [1][5]

For pot still Irish whiskey, the documents differ. The registered specification describes its malted barley as currently unpeated, while Revenue’s March 2023 scheme names peated or unpeated barley. [1][2] The supplied research record also records a 2026 Irish Whiskey Association request to delete that wording, with no approved change as of 5 November 2026. The proposal does not amend the recipe.

How to use the comparison

Start with the grain recipe to understand the names. Explore pot still for the technical file’s unmalted-barley spice and creamy texture; explore malt for its described fruity, floral and malty character. Neither category is a quality ranking. [1]

Then turn to the individual whiskey. Read the producer’s cask information and published flavour notes, keeping the category, distillation count and cask treatment separate in your mind. As the Teeling examples show, no one of those details gives a complete account of flavour. [3][4]
