A flavorful crisp beer is a popular, worldwide beverage. Beer can be either carbonated or nitrogenated, each giving a different sensory outcome. Carbonated beer, such as Budweiser, has a crispy and light texture, whereas nitrogenated beer, such as Guinness, has a creamy, smooth mouthfeel. A comparison study of these two different beer types was done using a Packaged Beverage Analyzer (PBA). The PBA is used to analyze the density, CO CO2, O 2, N 2, and alcohol content of various beverages, such as beer, sparkling water, and soda. The parameters assigned to the carbonated beer were container type and temperature at which it was stored. In contrast, the parameters for the nitrogenated beer were container type and widget variation. Consumers desire consistent tastes and longevity in their beverages, and these parameters could potentially impact the shelf stability and sensory outcomes of each type of beer.
