Espresso is made in a completely different way.

When making espresso, you need to grind the coffee finer. Once the grinding is done, you need to pour the coffee powder into a filter bowl and use a powder hammer and 30-40 pounds of pressure powder, so that the running water will not destroy the shape of the pressed powder and make the coffee extract more evenly and fully.

People usually use smaller porcelain cups or glasses to enjoy espresso, and drink it very quickly. Coffee extraction time is also shorter, usually between 15-20 seconds, the length of time will directly affect the taste of coffee.

The cup volume of a single Italian concentrate is usually only 25ml-35ml, which can be divided into extra thick Ristretto according to the length before and after the extraction stage and the amount of product.

Espresso . After these Italian nectar is done, add extra water to turn it into an American coffee Americano. So there are many ways to concentrate Italian style, not to mention all kinds of fancy coffee with milk, cinnamon and ice cream. Generally, the most common things encountered in China or the United States are the normal single strong Single and double strong Double.

The definition of the so-called "espresso" can be summarized as follows: the extract obtained by using high-pressure steam through a deeply roasted ultra-fine coffee powder. From a starting point, it should be said that Espresso is a very successful invention, because it can greatly reduce the use of coffee powder. The standard amount of coffee powder for a cup of Espresso is 7 grams, while a cup of regular coffee (100-120ml) needs 10-12g. At the same time, this brewing method has very low requirements for the quality of coffee beans-no matter what beans are roasted to the level of Italian, the original flavor of coffee beans is almost completely lost and transformed into scorched aroma and strong bitter taste. Finally, this method of soaking coffee is very simple and fast, and does not require much technology. As long as a little familiar with the use of the machine, a cup can be made in dozens of seconds. Espresso has these characteristics, and it is reasonable to be welcomed by fast-food coffee shops.
