What Irish Stout is like

A black, low-alcohol beer with pronounced roast reminiscent of coffee and a dry finish. The draft version is creamy and smooth despite its light body.

Appearance

Black or very dark brown with ruby highlights, opaque. Thick, creamy tan head with excellent retention, especially when served on nitrogen.

Aroma

Coffee-like or roasted-grain aroma, sometimes bitter chocolate. Low to no hops and restrained esters.

Flavor

Dry, coffee-like roast, with some bitter chocolate and medium bitterness that adds to the bitterness from the roasted barley. Dry, clean finish. It shouldn't be burnt or overly acidic.

Mouthfeel

Light to medium-light body with a creamy texture. Low to moderate carbonation; on nitro it's very smooth.

Where Irish Stout comes from

It grew out of the strong porters, the stout porters, brewed in London and Dublin in the 18th century. Guinness made it Ireland's best-known beer, and in the mid-20th century nitrogen dispense fixed the image of the style.

Ingredients

Pale ale malt with unmalted roasted barley, which gives the dry coffee character, and often flaked barley. English bittering hops and Irish or English yeast.

Brew it yourself

How to brew Irish Stout at home

Use about 10% roasted barley and the same amount of flaked barley, mash at 65-66 °C (149-151 °F) and ferment at 18-20 °C (64-68 °F). In bottles, carbonate low, around 1.8-2 volumes; if you have a keg with a nitrogen/CO₂ blend and a stout faucet, you'll get the classic creamy head. The classic mistake is using too much black malt so it turns acidic or ashy.

Food pairing

Oysters, beef stew or soda bread with butter.

Glassware: nonic pint glass, the classic pub glass, made for long drinks.

Classic examples

  • Murphy's Irish Stout
