People often ask why the beans have a strong flavor, but there is no fragrance after cooking. In fact, the sense of smell of the natural aroma can be clearly identified, and the bean phase can tell whether the beans are aging or not. if the aroma of ripe beans is too strong, you can first expose the coffee beans in the air for five minutes; if you place them for more than three days, you can clearly smell the fragrance, which is added with flavors or other additives, which may cause harm to the drinker's body. If you have the opportunity, you can try to compare the aroma of cooked coffee beans, it is not difficult to tell, if it is added coffee, you should choose not to drink it for the sake of safety.

What we also want to share is that the beans are ripe enough, the bean phase is dry, and the aroma is not long-lasting, while the bean phase is bright, greasy, and the aroma is too strong, which is likely to be aggravated by the essence. When you open the coffee bag and smell the mildew and oil smell of the coffee beans, please don't feel sorry if you don't drink them. Some people even think that they will not feel sorry for each other only after they have been given by their friends. That is simply hurting themselves. The aroma of real coffee beans is rich, the smell goes straight to the forehead, and in the entrance taste, it will make people feel happy, eliminate fatigue, and want to refill the cup.

Once again, good coffee can be judged by the appearance and color, slightly sour or slightly bitter taste is normal, because that is the performance of micro-fruit acid, chlorogenic acid and caffeine, must not be light coffee or charred black, light coffee color must be light roasted with high acidity; scorched black must be high bitter. Good aroma is by no means charred, why is it charred? In order to cover up the bad taste of shoddy ripe beans, we have to roast deeply. When the moisture is gone, the beans become lighter, and then fresh milk, cream and other additives are added to improve the aroma. In the end, the cost increases only to improve the flavor. Therefore, heavy deep roasting is charred coffee, not the so-called charred coffee.

Preservation of coffee beans

There is no special way to preserve coffee beans, which is what many people already know about sealed preservation.

If you have a choice, glass will be better than plastic containers. It is best to store coffee separately according to the type of coffee, even if the taste of coffee is similar, try not to put it in the same plastic container, because this will make the original aroma of coffee mixed together, and then it will be very difficult to make coffee with the original flavor.

On the contrary, there is no gas leakage from the glass container, so even if different kinds of coffee are put together, as long as they are arranged in order, the coffee beans can be well washed before use, and the original flavor can still be preserved. In addition, when saving the coffee, put the whole bag of coffee into the container together, so that the next time you want to change the coffee, it is very convenient to replace it.

Finally, it should be noted that there is no problem with the sealing function of containers, because there are many products on the market that claim to be sealed containers, but in fact some of them do not have the sealing function.
