Comparative studies on top note (the first impression of scent) of eleven kinds of black tea sold on the market were carried out. Aroma patterns were obtained by cryogenic vapor phase chromatography and acceptability was judged by organoleptic test. Correlation between prices and acceptability was also discussed. Comparing aroma patterns with acceptability of eleven kinds of black tea sold on the market, it was con cluded that linalool, n-pentanol, iso-pentanol, acetaldehyde, dimethylsulfide and ethylacetate contributed to the acceptable top note of black tea. It also was made clear that flavor-enriched black tea was easily recognized by cryogenic vapor phase chromatography because its aroma pattern was distinctively different from that of no-flavor-enriched black tea. The prices do not always guarantee the acceptability of black tea.
