Abstract


Beer is a known source of refreshment and the refreshment properties of beer likely come from a combination of different factors such as low temperature, carbonation, and alcohol. Previous studies have investigated how carbonation and temperature impact refreshment. Few studies have focused on the impact of beer flavor. The objective of this research was to investigate beer flavor and alcohol content on the perception of beer refreshment. An online survey was conducted to investigate consumer perception toward beer refreshment. Participants (n=1,050) indicted a refreshing beer was predominantly acidic in taste (lime: 51.7% of participants, lemon: 43%, orange: 40.5%, grapefruit: 35.7%), had a crisp and clean flavor profile (87.3% of participants), encompassed a cold/chilled temperature (95.4%), was carbonated (42%), and had a light flavor intensity (88.6%). A consumer test was conducted to determine if perceived refreshment was impacted by flavor (lemon, cucumber, citrus,) and/or alcohol percentage (0%, 2.5%, 5%, 7.5%). Consumers (n=326) evaluated their liking of refreshing, beer flavor, alcohol, carbonation, acidity, and bitterness attributes of formulated 12 beers using nine-point hedonic scales. Acceptance for all attributes was significantly different across all 12 samples (p<0.001). Pearson’s correlation analysis indicated that the liking of refreshing attribute strongly correlated with the liking of beer flavor, alcohol, carbonation, acidity, and bitterness. Cluster analysis (XLStat) uncovered four segments of consumers who were divided by acceptance of alcohol levels. The results of this study increased knowledge of the impact of flavors and/or alcohol content on beer refreshment perception which could guide beer development in industry.
