An Australian study found that even if it is exactly the same coffee, the use of different color coffee cups can make people feel different degrees of bitterness of coffee. This study may help coffee merchants and even ceramic merchants to increase their sales.
George Van Doorn, a professor in the Department of Psychology at the Commonwealth University of Australia, earlier invited dozens of people to carry out the experiment, using transparent, white and blue ceramic coffee cups containing the same coffee for those tested.
The results show that white coffee cups make people feel more coffee concentration than transparent coffee cups. The coffee in the blue cup will make people feel more sweet than the other two color cups. Perhaps the contrast between different colors and coffee can affect how people feel, Doren said.
Doren said that if coffee sellers want to increase sales or get more people to buy their products again, they should consider the color of coffee cups. The results have been published in the journal Flavour.
