How to store a coffee bag after it is opened?
Freshly roasted coffee beans are best placed in a check valve bag, because they are still venting. After 48 hours, they can be kept fresh in a glass jar.
If you do not have a glass jar, drain the remaining air in the container as much as possible after you have finished using the coffee beans in the bag or sealed jar to reduce the excessive contact between the coffee beans and the air. Or separate into small bags and squeeze out air for preservation.
Temperature requirements for coffee preservation
Keep out of the refrigerator at room temperature.
The air in the refrigerator is cold and dry, which tends to evaporate the moisture in the coffee beans, causing the coffee to lose its flavor.
If stored in the refrigerator, please note:
1. The packing should be absolutely sealed.
2. Don't unpack until the beans are back at room temperature (otherwise, fresh out of the fridge can condense moisture in the air. These small droplets can cause clumps in the ground coffee and lead to uneven brewing. The rate of microbial and oxidation at room temperature is quite appropriate).
What are the "little round holes" in the bags of ground roast coffee for
As a new coffee addict, I recently bought a batch of roasted beans. Found that almost all packaging, there will be a hard, round, with small holes. So I can smell the coffee?
The name of the small hole is "check valve".
Check valve, to speak a little more common, is that the valve is only out of the door.
Its role: explosion-proof bag + guarantee coffee quality
Air-only (explosion-proof bag) : Coffee beans will continue to release several times the volume of carbon dioxide of the coffee beans for a period of time after roasting. There are coffee bag ziplock. In order to prevent coffee packaging from bursting and isolation from sunlight and oxygen, a one-way valve aluminum foil bag is designed to discharge excess carbon dioxide out of the bag.
No air intake (coffee preservation) : In addition, the one-way exhaust valve can also block the outside of the oxygen into the bag, to avoid the coffee beans oxidation and resulting in the rapid release of flavor, so as to absolutely ensure the flavor of the coffee beans.
