"single coffee" generally refers to a single style of coffee beans from a single country or producing area. It can be compared to a coffee solo.

If a bag of coffee is marked with the name of a coffee-producing country (coffee beans are not produced in continental Europe, and if the label is marked with the names of European cities such as Italy, Vienna, etc., it is not individual coffee. (for the most part, it means this is a bag of coffee. For example, Ethiopia-Yega Snow Coffee (Ethiopia Yirgacheffe), Sumatra-Tawar Lake Mantenin (Sumatra Lake Tawar), Guatemala-Antigua (Guatemala Antigua), and so on, are produced in specific countries, producing areas, and estates, which are called "single coffee".

Because each country or different region has its own climate, soil and natural environment, the coffee grown has its own characteristics. Tasting "single coffee" can understand the characteristics and flavor of coffee in a certain country or region.

Italian coffee is based on the mechanism of Italian coffee, which uses 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 making time is quite short, the aroma of coffee is strong, and 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 current global coffee market, Italian coffee can be said to be the largest mainstream. Because of Italy's exquisite traditional craftsmanship and romantic national personality, these factors have made the trend of Italian coffee sweeping the world. Take Taiwan as an example. At present, people who drink espresso coffee 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 the coffee slices in Taiwan now belong to the Italian coffee shop type.

Espresso is ground into a finer powder than hand-brewed coffee, which is brewed under high pressure in an Italian espresso machine and can dissolve more coffee and filter out higher concentrations of coffee than other ways of making coffee.

In terms of brewing time on the semantic machine, the extraction speed is extremely fast: an average of 30 seconds can produce a cup of coffee, the steps are simple, making a set of SOP is easy to learn, and it has become the preferred brewing method for almost all chain coffee chains. Because the coffee beans can be seen by the concentration machine, set fixed brewing parameters to show the coffee bean flavor.

The grinding particles of hand-made coffee are thicker, and the whole brewing process takes about 3 to 4 minutes, paying attention to skills and techniques, from the degree of grinding of coffee beans, water temperature, water quality, water flow, extraction time, and even the technique and timing of water injection, the change of each small factor will have an impact on the final flavor.

Compared with the Italian concentrated machine, the fixed parameters can be used to provide stable coffee of the same quality, while hand-brewed coffee needs to master more details to fully show the level and flavor of each cup of coffee.
