Researchers from the Commonwealth University of Australia and the University of Oxford in the UK began to prove the truth after a barista said that white cups would make coffee taste more bitter. They found 36 volunteers to take part in the experiment and tested the claim with coffee cups in blue, white and transparent colors. In one of the experiments, volunteers thought white coffee cups "enhanced" the taste of coffee more than transparent coffee cups, according to an academic report published in the journal Flavour.

In the second experiment, the volunteers thought the coffee in the blue and transparent coffee cups tasted sweeter than the white coffee cups, and of the two coffee cups, the volunteers thought the coffee in the blue coffee cups was the sweetest.

Scientists believe that people may associate brown with bitterness, and because the coffee in a white coffee cup looks closest to brown, people will also think it tastes the bitterest. The lead author of the report, Dr George Doorn from the Commonwealth University of Australia, wrote in an article at the request of The Conversation: "our research clearly shows that the color of coffee cups does have an effect on people's sense of taste and smell when drinking coffee. Our academic report on the impact of coffee cup color on coffee taste suggests that coffee shop owners, baristas and porcelain manufacturers should all seriously consider the color of their coffee cups, because this potential effect can affect the number of repeat customers in their business.

Small coffee cups below 100CC

It is mostly used to hold strong and boiling hot espresso or individual coffee, such as espresso with only 50CC, Viennese coffee (concentrated + cream top) and macchiato (concentrated + foam top). Although you can drink it almost in one mouthful, you can taste it a little bit with a small coffee cup to prolong the pleasure of the coffee as much as possible. The Cappuccino with milk foam has a slightly larger capacity than Espresso. The wide mouth of the cup can show the rich and beautiful foam.

Ordinary coffee cups around 200CC

The most common coffee cups, light American coffee, mostly choose such cups, which have enough space to mix on their own to facilitate the addition of milk and sugar.

Mugs above 300CC or milk coffee cups for French Ole

Coffee with a lot of milk, such as lattes, American mochas and multi-purpose mugs, is enough to contain its sweet and diverse taste. The French are used to using a large bowl of milky coffee (Ole Coffee) to render a mood of joy that lasts all morning.

There are still traces to judge the difference between the teacup and the coffee cup from the shape and size. Usually, in order to retain the rich aroma of coffee and reduce temperature evaporation, the mouth of the coffee cup is narrower and the cup body is wider. On the other hand, most of the black tea cups have a wide mouth and high light transmittance to reflect the clear and transparent brown color.

[temperature]

A necessary step in making coffee is to warm the cup. In general, the top of the household semi-automatic espresso machine has a platform for holding coffee cups, which can heat the cup body. Once freshly extracted coffee is poured into a cold cup, the flavor will be greatly reduced. Therefore, the heat conduction and heat preservation of coffee cups are also critical to coffee tasting experience. In the process of making bone porcelain cup, an appropriate amount of animal bones is added to the raw material, which can slow down the decrease of coffee temperature, with a proportion of about 25% bone powder and 75% high-grade porcelain clay. Features: light texture (weight), strong light transmittance, soft color, high density (fragile, easy to clean) high temperature resistance (good thermal insulation)
