Dublin, Ireland
Guinness
The Dublin brewery whose dry stout became the reference point for the style worldwide, and the most widely recognised beer brand of any kind.
Also known as St James’s Gate, Arthur Guinness.
Guinness began brewing at St James’s Gate in 1759 and moved decisively into porter within a few decades, eventually abandoning ale entirely. Its use of unmalted roasted barley — shaped partly by malt taxation — gave its beer the sharp, dry roast character that came to define Irish stout as distinct from English porter.
Its technical contributions outlasted the beer. The brewery’s statistician William Sealy Gosset developed the t-distribution while working on small-sample quality control there, publishing under the pseudonym "Student" because the brewery treated the work as commercially sensitive. Nitrogen dispense, developed there in the late 1950s, changed how stout is served worldwide.
Why it matters
Defined dry stout as a global category, developed nitrogen dispense, and produced foundational work in applied statistics as a by-product of brewery quality control.

Reference beers
- Guinness 0.0
An alcohol-free version of the world’s best-known stout, made by brewing normally and then removing the alcohol.
- Guinness Draught
The nitrogen-dispensed Irish dry stout that is, for most of the world, what "stout" means — and a much lighter, drier beer than its colour suggests.
- Guinness Extra Stout
The bottled, carbonated Guinness — a sharper and more bitter beer than the nitro draught most people picture.
- Guinness Foreign Extra Stout
The strong, heavily-hopped export stout that predates the draught product by well over a century, and a completely different beer from the pint most drinkers know.
- Smithwick’s Irish Red Ale
The most widely distributed Irish red ale, and the reference point for a style defined by restraint.
BeerHQ carries only the products that anchor something. This is not the brewery’s full range.
Styles it is associated with
- Dry stout — Sharp roasted-barley bitterness over a light body and a very dry finish — much lighter to drink than its colour suggests.
- Foreign extra stout — A strong export stout, more intense in roast and body than a dry stout, historically brewed to travel.
Traditions
- Irish stout brewing — The Dublin divergence from London porter, built on unmalted roasted barley and later on nitrogen dispense.
