Espresso is Italian, mostly translated as espresso or espresso or espresso, meaning "I'll make coffee for you right away". Espresso can be said to be the largest mainstream in the current global coffee market.

Due to Italy's exquisite traditional craftsmanship and romantic national personality, these factors make the trend of espresso sweeping the world. Take Taiwan as an example. At present, espresso drinkers account for more than half of the existing coffee market, and almost all of them are young people with high spending power. Judging from the number of coffee shops alone, about 80% of coffee slices in Taiwan now belong to the type of Italian cafes.

What is espresso? To put it simply, espresso is to sit on the espresso mechanism and use atmospheric pressure to let hot water pass through freshly ground coffee powder to extract the essence of coffee. Its most important feature is that the production time is quite short, and the aroma of coffee is strong. Compared with other kinds of coffee, caffeine is also lower.

In addition, espresso is based on espresso, so the development is quite diverse, as long as different proportions of milk are added, a series of products can be extended, such as cappuccino, latte and other rich coffee.

In the minds of many people, the concentration of American coffee is not very high, because the concentration of American coffee is not as strong as that of Italian or Japanese, so Americans regard coffee as a general drink. the daily consumption is quite large, so for the sake of health, most American coffee shops will make the coffee in the shop quite light to reduce the existence of caffeine.

In terms of brewing method, American coffee shops mostly use orthodox American coffee machines, and the atmosphere of the whole shop is also formed by the fast pace of life. The reason why many guests visit American coffee shops is that the diversification and fast service of American coffee can let consumers take it and go. In the city with a tight pace of life, American coffee shops can be said to be a necessary presence in the United States.

What is the concept of blending of traditional Italian coffee beans?

From trying all kinds of machines, I understand the principle and science of extraction; from baking commercial beans, I feel the charm of shallow roasting; when I come into contact with boutique coffee, I see the mystery of the local soil. Mix beans with different characteristics, this is another world, general espresso beans are imported either from Italy or Seattle. I used to buy freshly roasted espresso beans directly from the origin, excluding the time factor of international shipment. to understand the purpose of deep baking. As far as individual coffee is concerned, although the flavor difference brought by the year is not big, these slight differences will be magnified after the beans are synthesized, so the deep roasting can facilitate the control of the quality to obtain the average taste, reduce the flavor difference brought by the year, and it is more durable to store.

In addition to espresso, lattes are mixed with milk and coffee, and the flavor concept is different. Here, the purpose of coffee is to highlight the sweetness of milk, so the objective goal of Latte is that the coffee itself is mellow, and after adding milk, it tastes like cocoa, so a good cafe should have more than two bean recipes, one for brewing espresso and the other for making lattes.

The common painful experience of all coffee beginners is that they do not know the objective criteria of coffee, including the flavor of beans, how fine they should be ground, how to cook them, and how long it takes to cook them. The Italian coffee machine provides a very precise standard, the traditional definition, the use of 9 atmospheric pressure, extraction time 25 seconds, brewing 30cc coffee, through the above standards, we can go back to determine the amount of beans, grinding thickness and filling pressure channel to achieve a standard extraction.

As the brewing of the Italian coffee machine will magnify and highlight the characteristics of the coffee flavor, we use the standardized brewing of the Italian coffee machine to find out the original flavor of the coffee (although it will be relatively strong), which can be used as a reference for the adjustment of the flavor and methods of other brewing methods. This is the inspiration given to me by the Italian coffee machine. In addition, in addition to the number of seconds, espresso can be used to determine whether the extraction is complete or not, and the cup can be opened immediately when the color of the outflow becomes lighter, which is also one of the advantages.
