How to distinguish the freshness and storage mode of coffee beans
There are tricks for distinguishing the freshness of coffee beans:
Nose smell: fresh coffee beans have a strong smell, otherwise tasteless or bad smell
See: good coffee beans are complete in shape and full in size, with fragrance coming out when they crack. On the contrary, the shape is incomplete.
Hand press: fresh coffee beans are pressed crisp.
Color: dark black coffee beans, the coffee brewed has a bitter taste; yellow coffee beans, the coffee brewed has a sour taste.
Use single stir-frying and baking. Fragrant and mellow after cooking
Good coffee beans: neat shape, bright color, stamina; bad coffee beans: different shapes, and incomplete individuals. After cooking, it is light and fragrant, not sweet enough.
The method of keeping coffee beans
Once coffee beans are roasted and ground, the heavier the unroasted or fried beans are, the better. The fragrance will be slowly lost, and if it is not vacuum-packed or properly stored, the fragrance will be gone after two weeks. So buy a small amount at a time, or a small amount of ground coffee. If you mail-order coffee from a coffee bean store, you'd better buy unground beans. Choose the appropriate packaging or container and store it in the appropriate space. However, fresh coffee is extremely sensitive to the storage environment. In recent years, experts highly recommend the packaging material of aluminum foil (opaque) with one-way exhaust valve (vacuum). It is praised and recognized by large manufacturers at home and abroad, blocking the invasion of oxygen and being able to discharge carbon dioxide, greatly prolonging the honeymoon period of tasting fresh coffee. As for storage, as long as it is placed in a shady place that is not susceptible to moisture and does not have direct sunlight. Frozen or frozen coffee beans (powder) is not absolutely ideal, the excessive shrinkage of the fiber is not as expected, which will cause the condensation of benign oil, the peculiar smell in the refrigerator and the temperature difference during extraction.
