Storage methods of coffee beans

There is a knack for distinguishing the freshness of coffee beans

Nose smell: fresh coffee beans smell strong fragrance, otherwise tasteless or bad smell.

Look at it: good coffee beans are complete in shape and full in size. On the contrary, the shape is incomplete.

Hand pressure: fresh coffee beans are fresh and crisp, and the fragrance comes out when they crack.

Color: dark black coffee beans, the coffee brewed has a bitter taste; yellow coffee beans, the coffee brewed has a sour taste.

Good coffee beans: neat shape, bright color, roasted by single stir-fry. After brewing and cooking, it is mellow and full of stamina.

Bad coffee beans: different shapes and incomplete individuals. After cooking, it is light and fragrant, not sweet enough.

Roasting of coffee beans

The more common distinguishing methods are cinnamon baking (CinnamonRoast), metropolitan baking (CityRoast), universal baking (Full-CityRoast), Viennese baking (ViennaRoast), Italian baking (ItalianRoast) and French baking (FrenchRoast).

The selection of raw beans, mastering the characteristics and structure of the roaster, and patiently repeating tests are the only way for a successful baker. The change of air and humidity in the working environment, the appropriate time for raw materials to enter the pot, the precise control of the heating procedure and time, how to adjust the exhaust gas valve, the cooling system and program, and even calculate the moving rate of each coffee bean in the boiler, have fully given coffee active vitality.

Preservation methods of coffee beans

Beans that have not yet been roasted or fried are as heavy as possible. once the coffee beans are roasted, they will slowly lose their fragrance, and 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 right packaging or container and store it in the right space, that's what it is, but fresh coffee is extremely sensitive to the storage environment. In recent years, experts strongly recommend the use of aluminum foil packaging material (opaque) with one-way exhaust valve, which is praised and recognized by large manufacturers at home and abroad, blocking the invasion of oxygen and being able to exhaust carbon dioxide, greatly prolonging the honeymoon period of tasting fresh coffee. As for storage, I think it only needs to be placed in the shade where it is not susceptible to moisture and does not have direct sunlight. Refrigeration or freezing is not absolutely ideal. Excessive shrinkage of fiber, condensation of benign oil, peculiar smell in the refrigerator and temperature difference during extraction are all thought-provoking.
