This means that the beer has smaller bubbles and a more creamy and stable head. [6] These less soluble inert gases give the beer a different and flatter texture. In beer terms, the mouthfeel is smooth, not bubbly like beers with normal carbonation. Nitro beer (for nitrogen beer) could taste less acidic than normal beer. [7]
The categories are varied and include processes or ingredients not usually regarded as defining beer styles in themselves, such as cask ale or gluten-free beer. [2] [3] [4] Beer terms such as ale or lager cover a wide variety of beer styles, and are better thought of as broad categories of beer styles.
