Pull flower practice beans had better be defective beans, cheap, but also required to be deep-baked, or choose Luodou, these two kinds of fat is the best, but usually choose cheap mixed beans, because poor beans will pollute the bean grinder, and can not drink, bad for health.

The machine for extracting espresso has the best extraction conditions, so the best extraction can be made no matter what kind of coffee is used. But the so-called "good extraction" will not only extract the maximum value of the good ingredients in the coffee; similarly, the bad taste will also be extracted the maximum value, which must be noted. Therefore, it is necessary to use good coffee with no defects in the material. If the coffee bean has its own shortcomings, as mentioned earlier. Shortcomings are also extracted in large quantities and magnified to unbearable levels.

All coffees have advantages, but they also have disadvantages, so instead of using single coffee to make espresso, various items are often mixed to make special coffee for the sake of richness and harmony.

Is the more crema, the better?

The thickness and maintenance time of coffee have a lot to do with the freshness of coffee. The richer the coffee is, the fresher the coffee may be; the more gas the beans produce during roasting, the more crema will appear. Take the coffee not long after roasting to extract, you can find that there will be a lot of crema, but unfortunately, it will also disappear in a faster time. When you taste this coffee, your tongue will feel the same way as when you drink carbonated water. Because the gas produced during baking dissolves in water, it will be bitter or astringent.

From this, it can be seen that even if it is fresh coffee, it cannot be said that it is all good coffee, and it still needs to be properly managed.

The ripening time of coffee beans varies depending on the baking method. Put the coffee in a state of isolation from light and oxygen for at least 3 to 4 days to more than 2 weeks, so that the gas produced during the internal baking of the coffee beans can be discharged naturally. With this kind of coffee, you can make a beautiful crema coffee.

In the stable state after extraction, the time is the best when crema does not exceed 3~5mm.
