Coffee beans or coffee powder, which one is better to buy?

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 it simple to measure, prepare extraction equipment and even clean up at the end.

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 is too superficial. In fact, 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 emitted. 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 part 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 and drink it within a few days, the taste will not change much. If you drink it soon, you can compare the freshly ground coffee with the old coffee. You will find that the old coffee will change a lot in taste and flavor.
