If you want to make coffee at home, should you buy coffee beans or coffee powder?

Many people are asking this question: If you want to make your own coffee at home, should you buy coffee beans or coffee powder?

There is no doubt that the answer is coffee beans .

Sometimes people think that buying coffee powder is a lot of hassle, as it can save time and trouble by skipping the step of grinding beans. But since you have decided to make your own coffee, why are you afraid of wasting time and effort? The skipped step will affect the taste of the whole cup of coffee. No matter how hard you try to make coffee, it will be useless because you have already lost at the starting line.

When we go to a coffee shop, we always smell the rich aroma of coffee as soon as we open the door. This smell is actually not what we imagine the smell of made coffee to be. To a large extent, it is the smell of ground coffee beans. Whenever you smell this smell, it means that some coffee substances have begun to evaporate, and the essence in the coffee is gradually decreasing.

The reason is actually easy to understand. After the coffee beans are ground into coffee powder, the area in contact with the air increases exponentially, which accelerates oxidation and volatilization. Dahua also said in the previous article "How to store coffee beans? Improper storage is equivalent to buying them in vain! Can they be stored in the refrigerator?" that oxidation and volatilization are the two major killers of coffee.

What substance in coffee beans is most likely to evaporate and become corrupt?

1. The aroma evaporates because the esters and aldehydes produced in the roasted coffee beans are the most volatile.

2. Acidic fats and volatile fats, which are important components of coffee's taste and aroma, oxidize and evaporate very quickly, resulting in a corrupt taste in the coffee.

This also shows how much oxidation and volatilization will affect the flavor of coffee. In addition, after the coffee beans are ground into coffee powder, they will not only oxidize and volatilize, but also absorb moisture in the air. If you use the moisture-absorbed, oxidized coffee powder to make coffee, how will the taste be?

Therefore, no matter how you preserve the coffee powder you buy after opening the bag, the flavor of the coffee will have been lost a lot, and it can only be regarded as mummified fragments of coffee.

Through the above analysis, it is not difficult to find that if you want to make a good cup of coffee at home, you still have to buy coffee beans, and the coffee beans should be consumed within half a month or a month after opening to prevent the volatilization of nutrients and aromatic substances.

If making a good cup of coffee is like building a house, fresh coffee beans and freshly ground coffee powder are the foundation and the roots.
