Coffee beans and coffee powder, how to choose?

When we buy coffee, we are often faced with two choices: coffee beans and coffee powder.

About 70% of the coffee products sold on the market are coffee powder. The advantage of coffee powder is that it is easy to use and easy to brew. The simple coffee extraction method, which is very popular nowadays, is probably the simplest method. Hang the filter paper on the cup and pour a cup of coffee powder into the filter paper. This not only saves the time of grinding coffee beans, but also makes the measurement, preparation of extraction equipment and even the final cleanup work simple.

Using coffee powder to brew coffee is indeed simple and convenient, but if it is widely praised only for this reason, then people's understanding of coffee may be a bit superficial. In addition, there are also big problems with powder products, because coffee powder deteriorates many times faster than coffee beans.

In the process of grinding coffee beans, about 70% of carbon dioxide will be dissipated. The remaining 30% of carbon dioxide evaporates several times faster than unground coffee beans. Carbon dioxide has the important function of preventing the deterioration of the environment around coffee beans (moisture, oxygen). If it is ground into powder, this effect will be greatly reduced. When carbon dioxide evaporates, it will also take away some of the aroma of coffee, so the aroma of coffee powder is not as good as that of coffee beans.

If you buy pre-ground coffee in a store, the taste will not change if you drink it within a few days. If you can't finish it soon, you can compare the freshly ground coffee with the old one and you will find out how much you pay for the convenience of using coffee powder.

In fact, people recommend powder products not just because they are convenient and simple. A coffee lecture once conducted a questionnaire survey, and when many people were asked "Why buy coffee powder?", they all answered: "Because I don't know where to buy coffee beans." This may be the real reason.
