How long can the half-cooked coffee beans last after grinding? how to drink the coffee beans after they are ground into powder

Most of them are one-way exhaust valve bags lined with aluminum foil. Aluminum foil can block light and air. The function of the one-way exhaust valve is to discharge too much carbon dioxide so that the bag will not burst without opening.

With pure water of about 96 degrees (must be pure water, otherwise it will affect the taste of coffee), evenly a small amount of clockwise water is drenched on the coffee powder, after the coffee powder is fully submerged, wait a while, after the first water is filtered into the cup, continue to pour a uniform small amount of water clockwise, watching the coffee liquid in the cup reach the desired amount, you can close the cup, and pour the cup counterclockwise. The added water should be determined according to the amount of coffee powder and personal taste.)

The bag is useless when you get the coffee beans. Because once the bean cultivation is completed, there is no need to let it exhaust again. When you press the exhaust valve around the smell of coffee, in addition to carbon dioxide, there are many fragrances are also discharged and lost. So changing the seal of the container is the first step, and when you want to drink coffee and open the lid, you will complete the exhaust.

For example, we use Kraft paper aluminum foil bags with one-way exhaust valves and seals that can be used repeatedly, but this kind of packaging is not suitable for long-term preservation of cooked beans. So the jar of the one-way exhaust valve is also not recommended.

Bean cultivation period: freshly roasted coffee beans (after thoroughly cooling) should be stored in a bag with an one-way exhaust valve as soon as possible. Although this is the freshest, but the texture is not stable, for example, there will be a large amount of carbon dioxide escape, so we need to wait patiently for the coffee beans to enter a stable state. This process is commonly known as "raising beans", and 1-2 days is the shortest period for raising beans. After this stage, it can be used to make drip coffee. If it is used to extract Espresso or cup test, the bean raising period should be appropriately extended, such as 5-7 days. But it is important to keep in mind that too much is not as good as too much, and that too long a period of raising beans can only do harm and no good.

The latest fresh period: calculated from the end of the bean cultivation period, if we cut the packaging of coffee beans and start grinding, there is no doubt that coffee beans are at the best stage of flavor at this time. If it is well preserved, this stage lasts about 2 weeks, and we might as well call it "the latest fresh period."
