Front Street-Coffee beans

Within a few days of the coffee cycle, beans enter a growing phase and begin to release carbon dioxide, as well as chemical changes that include sugar, carbohydrates, amino acids, water, protein, etc. It is most vigorous for five to seven days, and then gradually weakens. One-way exhaust valve can prevent air from entering the bag from the outside, one is to avoid moisture or contaminated gas outside the bag, the other is to allow these released carbon dioxide to be discharged, to avoid extrusion inside the bag, and to make part of the coffee beans can not be exhausted.

The one-way exhaust valve is not particularly magical. After removing the one-way exhaust valve by hand, she found that the one-way exhaust valve is not 100% one-way exhaust, and some extreme ways can still reverse the gas from the one-way exhaust valve. However, under normal non-violent circumstances, it was still appropriate.

In terms of taste, coffee beans are placed in one-way exhaust valves, and beans are placed in sealed places. In terms of the taste of coffee beans after the process of raising beans, beans with one-way exhaust valves are better than sealed beans.

If you choose to use a one-way exhaust valve for storage after the beans are exhausted, it is recommended to paste the one-way exhaust valve with a transparent sticker. Therefore, when choosing a one-way exhaust valve for sealing at the time of packaging and delivering it to the customer by express delivery, the one-way exhaust valve is a good choice. When the beans arrive by courier, it is the second thing, this time about the storage of beans. In the storage of beans, it is recommended to avoid light, moisture, sealing, and odor-free treatment.

There is no need to put the refrigerator. Since this time there is a championship champion who uses coffee to store below zero, there has been a saying that it is better to store coffee beans in the refrigerator. When the temperature drops, the internal structure of coffee beans will become more compact, which will indeed make the coffee taste stronger. However, the temperature stored during the competition is minus 75 degrees Celsius, while our domestic refrigerators generally cannot reach this level. If they must, they must be frozen.(Don't put it in the refrigerator. Coffee beans themselves have the effect of removing odors. If they pass through the box or bag containing beans, there may be a "refrigerator smell".) However, once the beans return to normal temperature, cold and heat contact, and the moisture or water droplets formed may be counterproductive.

Beans taste better after they have grown out of season. It is recommended not to interrupt the cultivation of beans frequently. When receiving the express delivery, open it to solve the craving and put it up to cultivate beans. After the beans are ready, they will give the biggest surprise. Different roasters bake beans at different times and the best flavor of beans are not the same, after the purchase can ask the merchant. and suitable brewing water quality.
