A Beginner’s Guide to Jameson: What’s Actually in the Range Beyond the Green Bottle

Jameson sells more than every other Irish whiskey combined, and most people have only ever tried the one in the green bottle. The range above it is where the Midleton distillery shows what it can really do.

A Beginner’s Guide to Jameson: What’s Actually in the Range Beyond the Green Bottle

Jameson is Irish whiskey to most of the world. It sells well over ten million cases a year, more than every other Irish brand combined, and it has been the engine of the category’s revival since the 1990s. But the green bottle that fills the shelves is only the base of a range that climbs through charred barrels, beer casks and single pot still releases to an 18 Year Old that bears almost no resemblance to the mixing whiskey it shares a name with. This guide walks through what each one is and why.

Where it comes from

Jameson was founded in Dublin in 1780 by John Jameson, a Scot, at the Bow Street distillery. For most of two centuries it was a Dublin whiskey. In 1966 the company merged with John Power & Son and the Cork Distilleries Company to form Irish Distillers, a consolidation of the survivors of a collapsing industry, and in 1975 production moved to a new distillery at Midleton in County Cork. Bow Street closed, and Jameson has been a Cork whiskey ever since; the Dublin address on the label is heritage, not geography.

Pernod Ricard acquired Irish Distillers in 1988 and built Jameson into a global brand over the following thirty years, with the United States as its biggest market. The Midleton distillery page covers the site; the Ireland region page covers the industry’s fall and rise.

What Jameson is made of

Jameson is a blend of two whiskeys, both made at Midleton.

The first is single pot still whiskey, Ireland’s native style: a mash of malted and unmalted barley, triple distilled in copper pot stills. The unmalted barley gives a spicy, oily, slightly green character that malt alone cannot produce. The single pot still style page explains the category in depth.

The second is grain whiskey, made from maize in column stills on the same site, light and sweet. Our pot still vs column still guide covers why the two methods give such different spirits.

The proportion of pot still to grain is what distinguishes most of the range. More pot still means more spice, texture and weight; more grain means more lightness and sweetness. Jameson does not publish the ratios, but it is a reasonable rule that every step up the range adds pot still.

All Jameson is triple distilled, unpeated and matured mainly in ex-bourbon casks, with sherry wood used in the upper tiers. The cask types guide explains what each contributes.

Jameson Original

The green bottle. No age statement, though the whiskey is generally at least four years old. Bottled at 40 per cent. It is light, soft and approachable: green apple, vanilla, honey, a faint floral note from the grain, and a mild pot-still pepper on the finish. It is built to be mixed — Jameson and ginger ale is the house serve — and it is one of the easiest introductions to whiskey of any kind. It is not a sipping whiskey by enthusiast standards, and it does not pretend to be.

Black Barrel

The first real step up. Black Barrel uses a higher proportion of pot still whiskey and a small-batch grain component, matured in bourbon barrels that have been re-charred — given a second flame-blackening to open up the wood again. The result is richer: toffee, vanilla, dried fruit, a nutty depth and a longer, warmer finish. It is still 40 per cent and still gentle, but it is a whiskey to drink neat, and for many it is where Jameson becomes interesting. Of the range below the age-stated bottles, it is the one to buy.

The Caskmates series

Caskmates began in 2015 as a collaboration with a Cork brewery: Jameson casks were lent out to age stout, then returned and refilled with whiskey. Caskmates Stout Edition picks up cocoa, coffee and a hint of hops. Caskmates IPA Edition, from 2018, is citrusy and floral with a slightly bitter edge. Both are standard Jameson with a beer-cask finish, and both are more interesting than they are serious. They work well in a highball. There have been numerous brewery-specific limited editions since.

Crested

Crested — formerly Crested Ten — dates from 1963 and was the first Jameson the company bottled itself rather than selling in cask to bonders. It has a high pot still content and is matured in a larger proportion of sherry casks than the rest of the standard range. The result is a surprisingly rich whiskey for its price: dried fruit, nuts, pot-still spice and a creamy texture. It is less widely distributed than it deserves and is worth seeking out.

Jameson Bold and the Distillery Edition

Occasional releases such as Bold, a higher-pot-still bottling aimed at bartenders, and the Distillery Edition sold only at the visitor centres, round out the mid-range. They are variations on the theme rather than new directions.

Jameson 18 Year Old Bow Street

The top of the core range and a different whiskey in character: a blend of pot still and grain, all at least eighteen years old, finished in first-fill bourbon barrels and bottled at cask strength, around 55 per cent. It is dense and complex — toffee, dark fruit, leather, oak spice, with the pot still finally dominant — and it belongs alongside the serious single pot still bottlings from the same distillery rather than with the green bottle. It is priced accordingly.

Why it tastes the way it does

Three production choices explain the Jameson profile, and all three are deliberate.

The first is triple distillation. Midleton’s pot stills run three times rather than the two that are standard in Scotland, producing a spirit that leaves the still at around 85 per cent alcohol, higher and cleaner than Scotch new-make. Much of the heavier, oilier character is left behind, which is why even the pot-still-heavy Jameson expressions are smooth rather than weighty.

The second is the absence of peat. Irish malt is dried with hot air, not smoke, so there is none of the phenolic character that defines much of Scotch. The gentle, cereal-sweet base that results is what lets the fruit and the cask show.

The third is the cask policy. Jameson matures overwhelmingly in ex-bourbon barrels, bought from the big Kentucky and Tennessee distilleries, with a smaller share of ex-sherry casks reserved for the upper tiers. American oak gives vanilla, honey and coconut; the limited use of sherry wood keeps the range from becoming heavy. Irish Distillers also seasons some casks itself, sending new barrels to Jerez to be filled with sherry before they come to Cork, a practice that gives it more control over the sherried component than most Scottish blenders have.

Put together, the result is a house style that is light, clean and sweet by design — and the reason that style is so easily dismissed is also the reason it has sold so well.

The pot still cousins

Any Jameson drinker who likes Black Barrel or the 18 should know that Midleton also makes Redbreast, Green Spot, Yellow Spot, Powers John’s Lane and Midleton Very Rare. These are not Jameson, but they are the pure single pot still whiskeys from which Jameson’s spine is drawn. If the spice and texture in the upper Jameson range appeal, Redbreast 12 is the natural next bottle, and the Irish whiskey style page maps the whole category.

Which to buy

For mixing: Original. First Jameson to sip: Black Barrel. For something richer at a fair price: Crested, if you can find it. For a special occasion: 18 Bow Street. For curiosity: Caskmates Stout.

Our tasting notes are collected in the reviews as we publish them, and our view is that Jameson’s value lives in the middle: Black Barrel and Crested deliver most of what the 18 does at a fraction of the price, while Original remains what it has always been — the most reliable mixing whiskey in the world.
