Which is better, coffee powder or coffee beans? How does coffee powder make coffee?

From the point of view of coffee flavor, the pre-ground coffee beans will accelerate the loss of coffee flavor. This is why most cafes, including Qianjie, recommend freshly ground coffee.

Why do we know that the flavor of freshly ground coffee is much better than that of pre-ground coffee, but there is still a big market for pre-ground coffee? A more direct reason is that these people who need coffee shops to pre-grind coffee do not have their own bean grinders, so they need coffee shops to grind them, which is common in some European cities.

They also know that freshly brewed coffee does taste better, but because there is no equipment, and pre-grinding does make it a lot easier to make coffee. If preserved in the form of coffee beans, coffee has a good flavor within a month. On the other hand, when it is ground into powder, the flavor will volatilize faster, perhaps only for about 10-15 days. People who use coffee as the main drink in foreign countries consume coffee faster, so they are less likely to account for the lost flavor. For domestic consumers who mainly use hand-brewed coffee, their own requirements for flavor will be more stringent, and the consumption of coffee is relatively small, so it is very easy to see that the flavor of coffee powder has not been finished yet. Therefore, although most cafes have a grinding service, guests are advised to go back and grind on their own. In this way, it seems that pre-ground coffee powder has a completely negative effect on the flavor. Another situation is that the generation mill is better than going back to the current mill, that is, when the performance of their own bean grinder is not very good. Everyone knows how important grinding is to flavor. It is important to master a suitable degree of grinding, and the uniformity of grinding is the top priority, most of which are caused by too much fine powder in the case of bitter taste.

The coffee shop has two advantages: one is that the grinding degree can be grasped more accurately, and the other is that the performance of the bean grinder is better (this depends on the specific bean grinder), and the uniformity of the ground coffee is high. In the face of freshness and grinding, Qianjie thinks that the degree of grinding should be chosen first. after all, no matter how fresh the beans are, it is difficult to drink even if the degree of grinding is not the right one, so it is better to drink more frequently. But if you really pursue the flavor of coffee, it is best to be equipped with a high-performance bean grinder. If hand-made pre-ground coffee powder, coffee does not expand, this is also a normal phenomenon. Because when the coffee is ground into powder, the rest of the coffee can be lost up to 70%. The rest of the gas will also lose faster than coffee beans. Therefore, when injecting water, there is not much gas in the coffee powder, so it will not expand.

So how to preserve the ground coffee powder? Qianjie here to provide you with some reference plans. Keep coffee beans or powdered coffee in a cool, ventilated and dry place without direct sunlight, because the high temperature will speed up the release of coffee flavor, so the taste period of coffee will be greatly reduced. At the same time, we need to pay attention to whether the storage location is wet, the humid environment will be easy to breed bacteria, so that the coffee will not only have a moldy taste, but also affect human health.

Completely sealed coffee beans can be sealed in the original package (if an one-way exhaust valve needs to be blocked), but coffee powder should be kept in a fully sealed container as far as possible. And try to reduce the number of times to open, because each time, the outside air will "invade" into the coffee powder.
