When it comes to uncarbonated beer, there are two main types that come to mind – nitro brews and cask conditioned beer. Nitro brews are quite popular and one of the most famous examples is Guinness Draught from Ireland. These beers are distinct in that they are infused with nitrogen instead of carbon dioxide, which gives them their unique frothy and creamy texture.
Nitro brews are typically served on draught and are poured using a specialized tap system that combines the beer with nitrogen gas as it is dispensed. The nitrogen bubbles are much smaller than carbon dioxide bubbles, which results in a smoother and creamier mouthfeel. This velvety texture is one of the defining characteristics of nitro beers.
Cask conditioned beer, on the other hand, is a traditional method of brewing and serving beer that predates modern carbonation techniques. Also known as “real ale,” cask conditioned beer undergoes a secondary fermentation inside the container (known as a cask) from which it is served. This process naturally produces a lower level of carbonation compared to other beer styles.
Cask conditioned beer is typically served at cellar temperature, which is slightly warmer than the usual serving temperature for most beers. This allows the flavors and aromas to develop more fully, resulting in a different drinking experience. The lower carbonation level in cask conditioned beer allows the flavors to shine through, making it a popular choice among beer enthusiasts who appreciate the nuances of the brewing process.
Both nitro brews and cask conditioned beer offer unique alternatives to the typically carbonated beers that we are accustomed to. The nitrogen-infused nitro brews provide a smooth and creamy mouthfeel, while cask conditioned beers offer a more traditional and nuanced drinking experience. Whether you prefer the velvety texture of a nitro beer or the flavors of a cask conditioned ale, both options showcase the diversity and creativity within the world of beer.
