Introduction to espresso technology: how long can roasted coffee beans last?
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.
Unroasted coffee beans
Coffee beans can be kept dry and unbaked for several years. During baking, the oil of coffee beans moves to the surface and spoils quickly. Therefore, after the coffee beans have been roasted, the storage mode becomes particularly important.
Roasted coffee beans
Whole coffee beans that have been roasted and released oil can be placed in an airtight container and stored in a cool, dry room temperature. Whole coffee beans can be preserved for a month under these conditions.
