People consume more than 2.25 billion cups of coffee across the world every day, and most say coffee tastes bitter.

Now, a new study suggests that coffee lovers can make their drink taste sweeter by simply changing the color of their cup. Scientists claim that blue and glass cups, which are popular in some coffee shops, reduce a coffee’s bitterness, without any need for sugar.

To prove their claim, scientists found 36 volunteers and used three different colored cups – blue, white and transparent (透明) glass – to do an experiment. In the experiment, white cup enhanced the flavor of coffee, which made coffee drunk from the white cup taste less sweet when compared to the other colored cups. The blue cup made the coffee taste the sweetest.

The scientists believe that the color brown may be associated with bitterness. So coffee in white cups, which appears the brownest, tastes the least sweet.

“The study suggests that café owners and baristas (咖啡吧服務(wù)員), as well a coffee cup manufacturers (制造商), should carefully consider the color of their cups,” said the scientists.

However, the idea that color can alter the taste of food and drink is not new.

A study published last year revealed that red, strawberry-flavored mousse served on a white plate was rated as 10 percent sweeter and 15 percent more flavorous than the same food presented on a black plate.
