How to make a cup of espresso-espresso extract

Similar to fine red wine and high-end black tea, the most direct reference for measuring the quality of coffee beans is their producing areas. The geographical and climatic characteristics of different producing areas and the "regional flavor" formed by the planting tradition are the soul of fine coffee. This coffee machine has not failed to live up to the standard of "intelligence", which is a small cash appliance. It can connect directly to your mobile phone APP and book the time for coffee brewing-- lying in bed early in the morning in confusion, you can order your machine to make coffee for you, although it is beautiful and ideal. What we are worried about is, does this counteract the pleasure of hands-on operation?

The temperature of boiling this kettle in 3 degrees 4 is about 80 degrees, and the temperature of hot water in a household thermos is about 80 degrees.

The thickness of coffee particles. Fine grinding, coffee particles for drip filter coffee machine and espresso machine can be used; if a blade grinder is used, the time required to grind two tablespoons of coffee powder is between 20 and 30 seconds; if it is found that the pressure bar is difficult to press down and the resistance is too high, it proves that the coffee grinding is too fine.

Pay attention to using a stronger coffee cup and hold it steady, so as to prevent the pressure from being too high when the push rod is too fast, which leads to coffee cup tipping or fragmentation.

Coffee roasting actually refers to how dark the final color of the coffee beans is (light or deep roasting) and how long it takes (quick or slow stir-fry). It is not enough to understate that a certain kind of coffee is lightly roasted, because the coffee may be stir-fried quickly or slowly, different roasting rates will have very different flavor performance, but the color of coffee beans look similar.

The coffee produced has no coffee fat.

This may be because the coffee grease disappears too fast. If this is the case, please refer to the "situation one" section. But if there is no coffee oil at all, it may be because your coffee has gone bad. Therefore, you must make sure to use your coffee beans within 21 days after baking.

When coffee is roasted, a series of chemical reactions take place, many of which lead to weight loss and, of course, water loss. Slow stir-frying is completed in 14 to 20 minutes, and fast frying can be completed in 90 seconds at most. For a relatively expensive cup of coffee, slow stir-frying will lead to better flavor development.

During the roasting process, there are three factors that determine the final flavor of coffee that must be properly controlled: sour, sweet and bitter. In general, the longer the total roasting time, the less sour it leaves. On the contrary, the longer the roasting time, the more bitter the coffee, and the deeper the roasted coffee will be.
