Front Street-how to grow beans for Coffee

When it comes to whether roasted coffee needs to be sold in an one-way valve. Because now many guests open the coffee beans as soon as they receive them. Then, after opening the bag, the tightness of the bag will not be so strong, and the effect of the one-way valve does not seem to be so great after opening the bag many times. In that case, can't you just give it to a bag without an one-way valve during express delivery?

During the few days of the coffee cycle, beans enter a growing period and begin to release carbon dioxide, as well as some chemical changes, including substances, carbohydrates, amino acids, water, and proteins. It is most exuberant in five to seven days, and then weakens gradually. The one-way exhaust valve can prevent air from entering the bag from outside the bag, one is to prevent moisture or polluting gas from entering the bag, and the other is to discharge the released carbon dioxide and avoid squeezing inside the bag. and some of the coffee beans can not be vented.

The one-way exhaust valve is not magical enough to exaggerate. After disassembling the one-way exhaust valve by hand, she Hua found that the one-way exhaust valve is not 100% one-way exhaust, and it is possible to reverse the gas from the one-way exhaust valve in some extreme ways. However, in the case of routine non-violence, it is still appropriate.

In terms of taste, coffee beans are placed in an one-way exhaust valve, and compared with beans in a sealed place, beans with one-way exhaust valves perform better than sealed beans in terms of taste.

If you choose to use an one-way exhaust valve for storage after the beans are deflated, it is recommended that the one-way exhaust valve be pasted off with a transparent sticker. Therefore, when the one-way exhaust valve is selected for sealing and delivered to the customer by express delivery, the one-way exhaust valve is a good choice.

When beans are delivered by express, it is the second thing, which is about the storage of beans. In the storage of beans, it is recommended to avoid light, moisture, sealing, no odor treatment.

There is a basic judgment. If you pick up a handful of beans and grind them and smell them, at first they are roasted (for me, they are roasted) and then they have a strong coffee flavor (flowers, fruits, nuts, chocolate, etc., mainly depending on the tonality of the beans themselves). On the other hand, the beans in the cultivation of beans will be very stuffy and the flavor will not come out.
