Coffee basics What kind of coffee is good coffee?

What kind of coffee is good coffee? Many white-collar MM often ask me this question. In fact, the charm of coffee is that it is difficult to measure whether it is good or bad by a simple standard. Each kind of coffee bean has its own unique flavor, and each roasting degree has its own favorite crowd, just as Italians like strong espresso and Japanese like to use siphon pots to make moderately roasted coffee. Of course, there is a basic standard for the quality of a cup of coffee.

What kind of coffee is good coffee? Fresh coffee is actually good coffee. Everyone wants to have a good cup of coffee, and they know that making a cup now may be fresh and will be fine. But many coffee drinkers have come to a misunderstanding. That is: either freshly made coffee is good coffee, it is fresh coffee.

This should start with the preservation of coffee beans. Raw beans, that is, beans that are not roasted, can be kept for a long time. As long as the temperature is right and it is not damp, it will be easy to release for several years, but it can also be regarded as old beans. Once baked, exposed to the air, 3 days will pass the best eating period. If it is packed at this time (with oxygen-resistant aluminum film nitrogen-filled packaging, it can be more than 1 year). If it is ground into powder, the flavor will be very different when exposed to air for 24 hours.

Fresh coffee has a strong aroma, no sour taste and strange taste.

The coffee after the best edible period has no taste, it has a strong sour taste.

At present, the preservation methods of coffee beans are more traditional, with the progress of science and technology, now coffee beans appear, sealed filled with nitrogen and antioxidant film preservation technology, do not open the package, can be as long as 2 years, when you want to drink coffee, every time you open a packet, it is equivalent to grinding a cup of freshly roasted coffee beans, aroma overflowing! However, the editor still tends to buy cooked coffee beans with different flavors, and is now grinding to make a cup of coffee that belongs to his own mood.
