Participants rated the parameters using a 5-point scale, which was weighted (really bad (x1); bad (x2); neutral (x3); good (x4); very good (x5)). The responses for each parameter were multiplied by their respective weight and totaled. There were 8 participants, of whom 2 were not able to sense aroma. The iron concentration in tea was adjusted to 4 mg per cup of tea.
