What is an Irish Nitro?

Answered by Joseph Earl

An Nitro refers to a specific style of known as a dry Irish that is served using nitrogen gas instead of the more common carbon dioxide. This method of serving creates a unique and velvety texture in the beer, with a smooth and creamy mouthfeel that is often associated with Guinness, the most famous example of an Irish Nitro beer.

The use of nitrogen gas in the dispensing process results in smaller bubbles, which gives the beer a dense and thick head that sits atop the dark liquid. This creamy head adds to the overall sensory experience of drinking an Irish Nitro, as it provides a visually appealing contrast to the deep, opaque color of the stout.

One of the defining characteristics of an Irish Nitro is its dryness. Unlike sweeter stouts or porters, the Irish Nitro has a more restrained level of sweetness, allowing the roasted malts to take center stage. The addition of Fuggle in this particular stout adds a tart bitterness to the beer, which balances out the richness of the flavors and contributes to the dry finish.

Aromatically, an Irish Nitro stout is known for its strong notes. The rich and complex aromas of coffee beans mingle with hints of light licorice, creating a sensory experience reminiscent of sipping on a cup of freshly brewed espresso. These coffee aromas are often a result of the roasted malt used in the process, which imparts flavors and aromas reminiscent of roasted coffee beans.

In terms of its drinkability, an Irish Nitro stout is often considered a sessionable beer. This means that it is lower in content, making it more suitable for enjoying multiple pints in a single sitting without becoming too intoxicated. The lower alcohol content also allows for the flavors of the beer to be more pronounced and enjoyed without overwhelming the palate.

As a brewer and sommelier, I have had the pleasure of experiencing and enjoying many different Irish Nitro stouts. One of my fondest memories is sitting in a traditional Irish pub, sipping on a pint of Guinness poured from a nitrogen tap. The smooth and creamy texture, coupled with the robust flavors of roasted malt and coffee, created a truly satisfying and indulgent drinking experience.
