9．More than 2.25billion cups of coffee are drunk throughout the world each day，and it's likely that many taste bitter．Now，a new study suggests that coffee fans can make their drink sweeter by changing the color of their cups．
Researchers from Oxford set out to prove whether the claim that coffee drunk from a white cup tastes bitter was true．They used 36volunteers and three different colored cups---blue，white and transparent（透明的） glass---to examine the claim．
In one experiment，the white cup increased the intensity （浓度） of the coffee taste relative to the transparent cup．Then，in a second experiment，coffee drunk from the white cup was found to taste less sweet when compared to the other colored cups，while the blue cup made the coffee taste the sweetest．
The scientists believe that the color brown may be associated with bitterness，and coffee in a white cup appears the brownest．"Our study clearly shows that the color of a cup does influence our sense of the coffee taste，"leading author Dr George Doorn，wrote in an article for The Conversation．"The effect of the color of the cup on the taste of the coffee reported here suggests that cafe owners should carefully consider the color of their cups，"he said，"The potential effects may spell the difference between a one-time purchase and a return customer．"Actually，the idea that color can change the food and drink taste came out many years ago．A study published last year reported that red，strawberry-flavored cake served on a white plate was rated as 10percent sweeter than the same food presented on a black plate．
