1. The air in the refrigerator is cold and dry, so it is easy to evaporate the water inside the coffee beans and lose the fragrance.

two。 There are too many odors in the refrigerator.

3. Due to the low temperature in the refrigerator, the coffee beans encounter relatively hot air when they are taken out of the refrigerator, which will condense into water vapor to cover the surface of the coffee beans. After grinding, these small water droplets will turn the coffee powder into lumps, resulting in uneven cooking and brewing.

4. As mentioned earlier, after the coffee beans have been roasted, the internal reaction continues. If the coffee beans are put in the refrigerator at this time, the coffee beans will be cold and stop the internal reaction, resulting in a loss of flavor.

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.

As soon as you open an oil-proof or tin foil-wrapped coffee bag, immediately put the coffee beans or coffee powder in a sealed can Coffee powder will not get moldy quickly, but just like coffee beans will absorb the smell in the air, 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 highly recommend the use of aluminum foil packaging material (opaque) with one-way exhaust valve, which is praised and recognized by big manufacturers at home and abroad. It blocks the invasion of oxygen and can discharge 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.
