How long can deep-roasted coffee beans be preserved? how should roasted coffee beans be preserved?

Deep baking:

Baking degree; micro-depth baking, also known as deep city baking.

The baking degree is slightly stronger than the medium depth, the color becomes quite dark, and the bitter taste is stronger than the sour taste. It belongs to the Central and South American baking method, which is very suitable for preparing all kinds of iced coffee.

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 the temperature difference between high and low during extraction are all thought-provoking.

A suitable place to store coffee

Coffee should be stored in a dry, cool place, not in the refrigerator, so as not to absorb moisture. Coffee beans and ground coffee can be frozen, but the only thing to note is that when you take the coffee out of the freezer, you need to prevent the frozen part from melting and dampening the coffee in the bag. Americans think coffee is better in the refrigerator. But it won't take more than a month. They took out the amount of coffee beans they wanted to drink from the freezer and began to grind and boil them to drink before they thawed.

Packaging that helps store coffee

Tin cans can keep the aroma of coffee for a long time. Plastic bags are fine, but they store less than tin cans. In foreign countries, coffee beans are sometimes sold in tin cans or plastic bags. Vacuum packaging is more conducive to the storage of coffee, making the original flavor more lasting.

Once you open an oil-proof or tin foil-wrapped coffee bag, immediately put the coffee beans or coffee powder in a sealed can; the coffee powder will not get moldy quickly, but will absorb the smell from the air as well as coffee beans.
