We often hear that "a rat shit spoils a pot of porridge." it's the same with making coffee. As long as a bad coffee bean is mixed into it, it will not only smell and taste astringent, but also cause throat locking and throat irritation. So next, we will provide a way to tell whether coffee beans are good or bad. From the point of view of the appearance, taste and color of coffee beans, it is not difficult for you to buy good coffee beans later!

(1) watch the nose, smell and touch hands, and make first-line contact with coffee beans

To tell whether coffee beans are fresh or not, you can make the most direct reference by making good use of your senses. When selecting coffee beans, use your eyes to see if there is any abnormal oil production on the surface of coffee beans. Under normal circumstances, shallow roasted beans will hardly produce oil, and there will be slightly dotted oil on the surface about 6 days after baking. If there is an abnormal large amount of oil produced, pay more attention to it when buying. In addition, close to the nose to smell the fragrance, the normal aroma should be rich, if with oil consumption, indicating that the coffee beans have been stored for too long, oil and air contact with the rancidity smell, that means the coffee beans are not fresh, not suitable to buy. Finally, the softness and hardness of coffee beans are known by the touch of the hand. under normal circumstances, coffee beans should be crispy. If they have become a little soft and wet, it is very likely that the beans have been kept for too long and the freshness is not enough.

(2) having a sip of black coffee, the advantages and disadvantages of coffee beans will immediately see the true chapter.

To distinguish the inner beauty of coffee beans, in addition to watching the hands touch, it is best to pass the taste judgment, with the mouth to taste the black coffee without any seasoning (such as milk, sugar, etc.) can see the clue. With a mouthful of black coffee in the mouth, gently with the tongue, and slowly swallow into the throat, if you feel the rotten smell, gutter smell, may contain local black beans in the defective beans; if you feel a sour bite in the throat after swallowing, it could be sour beans or worm-eaten beans. If the taste is clean and bright, the aroma is full, the flavor is layered, and the body does not have any discomfort, it is the good coffee extracted by good coffee beans.

See the freshness of the packaging

Coffee beans are a kind of agricultural products, so freshness is very important. when buying, you should pay attention to whether there is an one-way breather valve design on its packaging, which can smoothly discharge a large amount of carbon dioxide released by freshly roasted coffee beans. at the same time, it will not let oxygen in, reducing the number of contact between coffee beans and air to a minimum, so as to prolong the preservation time of coffee beans.

Try to find stores with open and transparent baking signs to buy.

When buying coffee beans, you should try to find shops whose roasting signs are open and transparent, because only in this way can you provide fresh coffee beans. In addition, when buying, ask the store about the baking time and compare it with the baking time marked on the bag to ensure the quality of the coffee beans. It is also recommended to buy coffee beans rather than coffee powder. Coffee beans are ground into powder to accelerate the volatilization of aroma and are not consumed immediately. It is easy to lose flavor when drinking.
