As a barista, coffee is our business card, and when customers order a latte, we also want to make a nice cup of flowers. It is also the happiest moment for every barista to see that customers are surprised or delighted with the pattern of flowers in the cup. But if you want to make a good cup of coffee, you should not only focus on foam and extraction, but also pay attention to the choice of cups. Do you know what kind of cups are more suitable for making coffee flowers?

First of all, let's briefly talk about the principle of coffee flower formation, which makes the following explanation easier to understand. To put it simply, make a good latte: high-quality Espresso (espresso) and dense milk foam are essential.

Coffee beans will emulsify the insoluble oil of coffee powder under high temperature and high pressure, and a large amount of carbon dioxide will be dissolved into the liquid. At this time, in order to stabilize these small bubbles, coffee makes these bubbles stable and elastic through "protein melanin". This is what we often call Crema (coffee oil). And how to get high-quality Crema? First of all, the freshness of coffee beans is the most important, the use of fresh coffee beans in the extraction process can make Crema lasting, sufficient and thick; then, the correct grinding degree is an important reason for the extraction of high-quality Crema, the wrong grinding degree will make the coffee flow rate too fast or too slow, resulting in Crema can not reach the best state.

Another important key is the formation of milk bubbles. The difference between milk and milk bubbles is that the addition of steam in the process of milk bubbles causes milk protein to form many dense and small foams under the action of surface tension. High fat can make the structure of milk bubbles more stable and lasting, so skim milk is not easy to send away milk bubbles.
