What you need to know about buying coffee beans: rules for choosing coffee

Good coffee needs a good growing environment, a "matching" climate at that time, a barista who has a deep understanding of coffee beans in the process of grinding and filling coffee, and several aspects that cooperate with each other to make a perfect cup of coffee. We suggest that under the premise of conditions, try to buy vacuum coffee beans, not coffee powder bricks.

Coffee beans need to be roasted before they can reach the peak of their flavor. Although coffee beans should be drunk fresh, they are not as fresh as possible. Just like red wine, some wines should be drunk that year, but they also have to be aged in wooden barrels for three months. Some wines have to be aged for three to five years before they leave the factory, and then they have to grow in the bottle for a few more years to reach the best taste. Generally speaking, when you buy the coffee beans home, tie the beans in an ordinary plastic bag, and find that the bag rises the next day, it shows that the coffee is still in a very dynamic stage. Oxygen and humidity are the enemies of coffee preservation. Do not keep coffee in the refrigerator.
