The objective of this study was to produce high-quality microbial fermented tea by isolating and identifying microorganisms from nuruk. The isolated microorganisms were analyzed by internal transcribed spacer (ITS) region sequencing and the isolate was identified as Aspergillus sp. B3. Tea leaves were then inoculated with the identified microorganism. The changes were observed and the metabolites formed were analyzed according to the fermentation period. The total polyphenol content of the fermented tea was measured on day 0, 3, 5, 7, 10, a total of 5 times. The total polyphenol content decreased by 35% on day 10 compared to the initial content before inoculation on day 0. A total of 28 metabolites were identified in the fermented tea with the results of the PLS-DA score plot and those of UPLC-Q-TOF MS, using LC/MS, and GC/MS analyses. As fermentation progressed, the content of simple sugars, organic acids, and catechin-based substances decreased, and those of sugar alcohols increased. The content of glutamine increased significantly among the amino acids present, whereas those of alanine, serine, threonine, aspartic acid, and 5-oxoproline decreased. Furthermore, the fermented tea showed increased levels of several fatty acids, including lysophosphatidylcholine (LPC 18:1, LPC 18:2, and LPC 18:3), but the levels of palmitic acid, stearic acid, glycerol, and 13-docosenamide remained unaffected. The results of this study could be used as basic research data for further analyses of fermented teas using Aspergillus sp. B3 and their secondary metabolites and could also have an influence on the production of Korean-style microbial fermented teas through studies of a variety of such teas according to their fermentation period.
