In order to brew the top espresso, [4m] blending and integration is very important.

The first ● is [Mistura]. It means espresso beans. Italian espresso beans have at least five kinds of espresso beans.

Coffee bar owners must be aware that they use several coffee beans to integrate espresso beans. This is to know what your own espresso tastes like. Learn more about coffee beans to understand the guests. What kind of espresso beans do you have in your store? "but when guests ask this question, if the answer is" not clear ", I think it is difficult to enrich coffee for more delicious people to know, so the choice of coffee beans must ask the industry to remove relevant information.

The second M of ● refers to [Macinino]. That's how coffee beans are ground. The ideal condition for coffee powder is to boil with 7G coffee powder, which can burn 20Cc-35cc espresso coffee in 20 to 30 seconds. In order to achieve this ideal state, it is necessary to find the most suitable grinding method. Because this has something to do with the adjustment of the grinder, the so-called appropriate grinding methods will vary according to the use of different types of coffee beans.

First try to do it once, if it is finished in less than 20 seconds, you can reduce the fine a little bit. On the contrary, if espresso only drops in autumn, it takes more than 30 seconds to complete, it is necessary to adjust it a little bit. It is important to note that the refurbished coffee powder cannot be dropped immediately after the scale is changed. Since the grinder is also mixed with debris and ground, the scale and regrinding time are adjusted for 10 seconds so that the residue in the grinder falls together in the coffee powder.

In addition, pay attention to the bean storage tank at the bottom of the bean before grinding, if there is too much residue, it will be overweight because the weight of the coffee bean enters the cutting part, but on the contrary, there is too little residue, and the amount of grinding and falling coffee powder will be roughly the same. Therefore, it should be noted that soybeans are often stored in 6-7 cups of soybeans.

It is also important to first reduce the weight of a good grinder handle to 7g. In addition to keeping the right amount of coffee powder on the filter handle at a time, each cup of coffee can be pulled twice as long as it is pulled once, so that the brewing operation can be carried out smoothly. After all, pulling the handle all the time will also burden the handle spring and it is easy to loosen.

Again in advance, write down all the grinders in a few seconds, grind a few grams of coffee powder, and you can put a certain amount of coffee powder into the chlorine handle.

The third M of ● is [Macchina], which refers to the coffee machine. In order to be able to use boiling water at 90 degrees Celsius, apply 9 pressure, and brew espresso between 20-30 seconds, there must be a very good professional coffee machine performance. Espresso at about 90 degrees Celsius, 9 pressure, in order to lead the top tasteless. Lower than 9 low pressure, then not only can not lead to the taste, but also flushed out white espresso. On the contrary, if the pressure is too high, there will be miscellaneous smells.

In addition, we also need to master the characteristics of the coffee machine. For example, when I start brewing with [CIMBALI], I don't immediately fall off espresso. This is because the machine is equipped with steam function, so it starts to brew at the same time in about 4-5 seconds. In order to make the steam performance of the machine play a greater role, in order to steam all the coffee powder, the coffee beans had better be ground.

The last one in ● is [Mano]. It means the technician, the owner of the coffee bar. If there is no one as mentioned above, carefully adjust the grinding conditions of coffee beans, familiar with the performance of coffee machine coffee shop, coffee shop owner, you can not make delicious espresso. However, it is not possible to pay too much attention to the cooking process and delay in brewing delicious espresso for guests. In order to take into account the speed of service, I think a large number of coffee beans should be prepared in advance, and 7g powder can be guaranteed to enter the filter handle.

Then fill the hand with coffee powder as soon as possible. Because the filter itself has a certain amount of heat, if the coffee powder is installed in it for too long, then the heat will reduce the quality of the coffee powder.

I believe many people are just used to grinding fresh coffee powder in order to make delicious espresso.

But is that really the case? Just ground coffee powder and friction after the production of heat gas and natural gas, this is if the use of 9 pressure and 90 degrees boiling water brewing coffee powder will not only scorch, but also produce unpleasant taste. In the past, I had to grind coffee powder with illy coffee beans for a week and then brew it for testing. As a result, not only the color of the beautiful coffee foam can be boiled, but the taste has not changed. Because generally speaking, coffee powder usually takes up to 10 days to taste.
