How long is the shelf life of coffee beans after baking?

Fresh beans are suitable for sealing and preservation in a bag with an one-way exhaust valve. be sure to empty the air in the bag as much as possible after use, and then keep it sealed. Usually put beans in a cool and ventilated cabinet, as long as it is not close to the heat source is not a big problem. If it's not for special reasons, don't put beans in the fridge! Keep it in a cool place at room temperature. Because the low temperature of the refrigerator will bring condensed water to the package. This is the sweet coffee! If you really don't have time to drink, but the beans are very good, those you don't want to throw away can be frozen in the freezer and thaw later. Although the flavor will certainly be greatly damaged, it is better than throwing it away.

Good coffee beans should be sealed and preserved as soon as possible. It is said that beauty is easy to grow old, and so are coffee beans. The peak stage of coffee bean flavor usually lasts only 2-3 weeks, no more than 1 month at most, so we can also think that the shelf life of coffee beans is 1 month. Of course, aging can be properly delayed by some man-made means, such as filling inert gas, etc., but after all, coffee that cannot be reversed by manpower should be stored in a dry and cool place and must not be stored in the refrigerator to avoid absorbing 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. 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.
