How many days can roasted coffee beans be kept? Coffee origin

Roasted coffee can be placed for more than a year if it is not exposed to sunlight, but the taste will change. Roasted coffee is best based on the roasting date. It is recommended not to put too much in a month or it will mold. Remember not to exceed a year. However, it is better to use it within half a year. The roasting degree is slightly stronger than the medium and deep roasting degree. The color becomes quite dark. The bitter taste is stronger. It belongs to the Central and South American roasting method. It is very suitable for all kinds of iced coffee.

The beans that have not yet been roasted or fried sink better, and once the coffee beans are roasted, they slowly lose their flavor, and after two weeks the flavor is gone. So buy a small amount at a time, or buy a small amount of coffee that has been ground. If you order coffee from a specialty coffee shop, it's best to buy unground beans.

Choose the right packaging or container, stored in the appropriate space, is the case, but fresh coffee is extremely sensitive to the storage environment, in recent years experts strongly recommend the use of aluminum foil packaging materials (opaque) with one-way exhaust valve, for domestic and foreign manufacturers praised and recognized, blocking the invasion of oxygen and able to discharge carbon dioxide, greatly extending the honeymoon period of tasting fresh coffee. As for storage, I think it is only necessary to place it in a shady place that is not easy to damp and direct sunlight. Refrigeration or freezing is not absolutely ideal. Excessive shrinkage of fiber, condensation of benign oils, peculiar smell in the refrigerator, and high and low temperature difference during extraction are all thought-provoking.

A good place to store coffee

Coffee should be stored in a dry, cool place and never in the refrigerator to avoid moisture absorption. Coffee beans and ground coffee can be frozen. The only caveat is that when taking coffee out of the freezer, you need to avoid melting the frozen part and making the coffee in the bag wet. Americans think coffee is better kept in the refrigerator. However, it would not take more than a month. They take the coffee beans out of the freezer and grind them before they thaw.

Packaging for coffee storage

Tin cans can make coffee aroma stay longer. Plastic bags can also be stored, but less than tin cans. Coffee beans are sometimes sold in tin cans or plastic bags abroad. Vacuum packaging is more conducive to the storage of coffee, so that the original flavor more durable.

Once the oil-proof or tinfoil bag is opened, place the coffee beans or coffee powder in an airtight jar; the coffee powder will not mold quickly, but like the coffee beans, it will absorb the flavor in the air.
