You may have heard the term floated around in a brewpub, or perhaps you’ve even sampled this unique beverage. But what is nitro beer precisely, and how is it different than other beers?
For the past 60 years, nitro beer has done nothing less than revolutionize the beer industry. More specifically, many stout beers like Guinness have been entirely changed through the use of the nitro gas process.
In this article, we’ll sip our way through the history of nitro beer and what sets it apart from the rest. We’ll even throw in some of our favorite nitro beers at the end of the article.
What Is Nitro Beer?
Since nitro beer’s development, it’s been increasing in popularity with craft breweries and taprooms around the world. The name itself refers to how nitro beer is made. Nitro beers are made by utilizing a 70 percent nitrogen and 30 percent carbon dioxide mixture to provide beer with a very light carbonation and a thick and creamy foam head. Drinkers are often delighted with the carbonated bubbles that appear to float down to the bottom of the bottle instead of up.
Does Nitro Beer Taste Different?
Drinkers of nitro beer can definitely expect a uniquely textured mouthfeel reminiscent of smooth cream and dotted with miniature bubbles. But what does the beer taste like? The answer to this question depends on the beer itself that is being processed with the nitrogen; however, many beer drinkers claim that beer infused with nitrogen has much more accentuated, balanced, and intense flavor.
There is no denying that nitrogen-infused beer does have an impact on the beverage’s taste. Nitrogen does tend to overpower the flavor of hops, meaning that beers that are malt-forward or stronger in flavor can often better benefit from this beer style.
The History of Nitro Beer
In the late 1950s, a mathematician at Guinness, Michael Ash, was looking for a way to produce the “perfect pint” and simultaneously improve the shelf life of bottled Guinness beer. In an interview with Good Beer Hunting, the current Guinness Ireland archive manager Eibhlin Colgan explained Guinness initially used to be stored in wooden casks and left the bottling to the bar publicans. It was seen that a change was needed in the way Guinness was stored and distributed when the demand in England for the stout beer began to increase. This is because beer drinkers in England preferred fast and cold lagers. Unfortunately, while some pressurized cask versions existed, they were often difficult to use and took a while.
Using his experience in the beer industry, and by implementing a love and understanding of math, Ash set out to develop a new draft system to improve Guinness beer delivery. With nitrogen and a two-chamber cask, Ash initially developed the solution prototype by 1957 and had a subsequent finished design and patent for Guinness by 1958.
Following the design and implementation of Guinness’s new nitro system, beer pubs and distributors outfitted with the device began seeing up to a 25 percent increase in sales. This change led to a notable corner being turned that impacted the way Guinness would be served and enjoyed from then on.
While stout beer is often associated with nitro, you can now find IPAs, ales, and other beer styles being served or packaged utilizing nitro methods. The coffee industry has even latched on to the use of nitrogen in brewing some cold-brewed drinks. In 2016, coffee giant Starbucks released a Nitro Cold Brew coffee that became a massive hit with consumers by 2019. We’ll explore some of the most popular beer brands who’ve perfected nitrogen use towards the end of this article.
Why Some Beer Drinkers Don’t Like Nitro Beer
While many beer drinkers appreciate nitro beer, some feel it was an unnecessary development that changes the taste of beer negatively. Non-believers in nitro often think that the beer goes flat too quickly and that the hops’ flavor is diminished too greatly, thus reducing the overall taste and enjoyment of the beer.
