Beer flavor is not static; it is in a constant state of change requiring sensory analysis at each stage. Therefore, aligning pre- with post-production best sensory practices will ensure high quality and stability across the market. This study describes the sensory evaluation of seven brands in three seasons, represented by nine batches sensory analyzed at critical control points in their production (incoming water, brewhouse water, fermenting beer, conditioned beer, filtered beer, beer in bright tank, deaerated water, CO2, O2, N2 and filters). In total, 2,765 samples have been tasted by a professional in-process panel. The results will highlight the range and intensity of dominant off-flavors in the production of each brand. The findings will then be used to advise the producer about prevention steps needed in earlier stages of production and maximize freshness, drinkability and product stability. Tasters have been trained and validated on 28 GMP Flavor Standards that are used globally by professional in-process panels within the beer industry. The project aims to improve understanding the origins of beer aging non-conformance in different stages of production, comparing tasting with instrumental data, monitoring and preventing faults and recalls. The study results are considered to be suitable to monitor beer flavor stability.
