Growing altitude, Tea amount, Brewing time, Multisensory rating


The present study proposed a systematic approach to investigate the factors that might affect the multisensory rating (MSR) of oolong tea based on participants’ point of view. There were three independent factors investigated: growing altitude, tea amount and brewing time. The results showed the three main factors all significantly affect the MSR. A high growing altitude of 1000m results in better MSR than a low growing altitude of 300m. In terms of tea amount, 2.0g and 2.25g results in better MSR than 1.75g and 2.5g. Brewing times of 60s and 75s resulted in better MSR than 45s. In summary, a growing altitude of 1000m, tea amounts of 2.0g and 2.25g, and brewing time of 60s were the best brewing combinations for experienced consumers when using a 120ml porcelain teapot and a water temperature of 95°C. Further, the results also imply there might be an optimal range of tea amount and brewing time for oolong tea.
