Understanding Nitro Beer
Nitro beer is a delightful and distinctive type of nitrogenated beer, infused with nitrogen gas, resulting in a creamy texture and an iconic cascade of tiny bubbles.
These beers stand out from their carbonated counterparts due to their smoother, creamier mouthfeel, and the unique sensory experience they provide.
The cool cascade effect that occurs when pouring a nitrogen beer is a result of nitrogen being exposed to an atmosphere with significantly lower pressure than that inside the keg or can.
Nitro beers are typically served on draft where the nitrogen facilitates a greater expression of flavor compared to beers served with carbon dioxide.
As a result, the “nitro” style has become increasingly popular in the craft beer industry, offering a velvety mouthfeel that many beer enthusiasts find irresistible.
Nitrogen vs. Carbon Dioxide
While carbon dioxide is the most common gas used to carbonate beer, nitrogen has its own unique characteristics that make it a popular choice for certain styles.
Nitrogen produces smaller bubbles and a richer texture, resulting in a creamy mouthfeel that distinguishes nitro beer from carbonated beer.
The use of nitrogen in beer has become increasingly popular among craft breweries, as it allows for a smoother mouthfeel and a unique sensory experience.
Conversely, carbon dioxide has a higher solubility than nitrogen, making it more appropriate for hop-forward beers that require a more pronounced flavor. Nitrogen’s lower solubility takes longer to dissolve in beer, producing smaller bubbles and resulting in a unique mouthfeel and smoothness for nitro beers.
The Role of Tiny Bubbles
The secret to nitro beer’s allure lies in the tiny nitrogen bubbles that create a thick head and velvety texture, providing a sensory experience unlike any other beer.
The presence of these small bubbles in nitro beer results in a thicker head and a smoother, creamier texture.
The cascade effect in nitro beer is an attractive visual element, as nitrogen rapidly descends, forming a light and aromatic foam on top, and then escapes upwards and outward along the sides of the glass.
This captivating effect not only makes nitro beer a pleasure to drink, but also a delight to watch being poured.
The Origins of Nitro Beer
The story of nitro beer began in 1959, when Guinness first developed the concept to replicate traditional hand-pulled beers and ensure uniformity. By experimenting with nitrogenation, Guinness aimed to recreate the velvety, full-bodied texture of cask ale and establish consistency across their products.
The “cascade effect” in Guinness beer is achieved by using high pressure nitrogen to push the beer through small holes in the tap, creating a cascading effect and a creamy texture. This innovative approach to beer production paved the way for the future of nitro beer and its growing popularity among beer enthusiasts.
Evolution of Nitro Beer Technology
As the popularity of nitro beer grew, so did the technology used to create it. The “Easy Serve” system, designed to replicate beer served from wooden casks, was introduced in 1989. Another significant advancement in nitro beer technology was the introduction of the “widget can” by Guinness in the same year.
This small ball of nitrogen was implemented in Guinness bottles and cans to achieve the desired cascade effect and creamy texture when the beer was opened.
The future of nitro beer technology is anticipated to include an expansion in styles and flavors, as well as advancements in sustainability and packaging.
Brewing Nitro Beers: Techniques and Styles
Brewing nitro beer requires special techniques and equipment, and is typically crafted with robust, chocolatey porter or stout. Nitrogenation of nitro beer is accomplished by combining nitrogen and CO2 under elevated pressure, either before packaging in pressure-sealed kegs or in-line on the way to the draft system.
The nitro drafts feature a restrictor plate which is designed to channel the beer through tiny holes. This allows the nitrogen gas present in the beer to escape quickly, resulting in a cascade effect and creamy texture.
Infusing Beer with Nitrogen
Incorporating nitrogen into beer is a precise process, with the optimal proportion being 25% carbon dioxide and 75% nitrogen. Nitrogen is introduced from a pressurized tank post-kegging or bottling to achieve the desired creamy mouthfeel and unique sensory experience.
Since there is no equipment available to measure nitrogen levels within beer, it is necessary to rely on sensory methods to ensure the beer appears satisfactory when poured.
Nitrogen also serves to neutralize bitterness, resulting in stouts that are more roasty or sour beers that are more fruit-forward.
Popular Nitro Beer Styles
Popular nitro beer styles include stouts, porters, and coffee beers, all of which showcase the smooth, creamy texture that nitrogen imparts on beer.
From Guinness Irish Stout and Left Hand Milk Stout Nitro, to innovative offerings like Firestone Walker’s Nitro Merlin Milk Stout and Samuel Adams Nitro Coffee Stout, there is a wide variety of nitro beer styles to suit every palate.
As the popularity of nitro beer continues to rise, so does the variety of styles available, making it an exciting time to explore this velvety world of beer.
Serving Nitro Beer: Pouring and Presentation
Serving nitro beer not only requires an understanding of the unique brewing techniques involved, but also the proper pouring and presentation methods. To ensure the perfect pour and the desired cascade effect, the “hard pour” technique is employed.
It is also important to serve nitro beer at the correct temperature, typically between 40-45°F, in a pint glass to maintain the nitrogen bubbles and prevent over-foaming.
The Art of the “Hard Pour”
The “hard pour” technique is a crucial aspect of serving nitro beer, as it involves pouring the beer at a 180-degree angle into a 16oz glass to activate the nitrogen.
The pouring technique for the “hard pour” involves pouring the beer from the nitro tap into a glass at a 45-degree angle until the glass is two-thirds full, pausing until the foam fully resides, and then filling the now-level glass.
The angle and level of the glass are essential for guaranteeing that nitrogen is adequately activated and that beer is poured accurately. Allowing the foam to settle is crucial for ensuring the beer is poured correctly and that the nitrogen is properly activated.
Temperature and Glassware
Temperature plays a significant role in maintaining the ideal characteristics of nitro beer. Serving nitro beer at 40-45°F helps to preserve nitrogen bubbles and prevent over-foaming, ensuring the perfect pint every time.
The type of glassware used also affects the overall experience of the beer. A pint glass is recommended for serving nitro beer, as it provides ample space for the cascade effect and the thick, creamy head that is characteristic of this unique beverage.
