Isn't it best to enjoy coffee beans in time after roasting?

How many days is the best time to enjoy coffee beans?

On this issue, the benevolent see benevolence, the wise see wisdom. Coffee beans will be exhaust after roasting, that is, the volume of raw coffee beans will expand when roasted, and the expansion space in the coffee beans retains carbon dioxide.

Over time, this carbon dioxide will gradually break away from the coffee beans. This is why coffee beans need to be packed in coffee bags with one-way exhaust valves, because roasted coffee beans will exhaust (carbon dioxide). If you seal the coffee bag, the coffee bag will swell, and the thinner coffee bag will even break. The one-way exhaust valve can also discharge the gas and prevent the entry of moisture and oxygen at the same time.

Some people say that when coffee is brewed, it is correct to see rich bubbles (bubbles) that represent good coffee, or rather fresh coffee. Coffee is really the most exuberant when it is roasted. If the coffee exposed to moisture or contact with oxygen will accelerate the aging rate, the flavor will go bad, this is indeed an indicator of whether the coffee is good or bad.

When brewing espresso coffee, it is not easy to control using coffee beans and powder that are too fresh. The pressed powder layer will expand, high pressure and high hot water will pass through the powder layer, and the exhaust will become very unstable. What needs to be done is to raise beans and wake up beans.

There are many theories about how to raise beans. For example, coffee beans are sealed in an aluminum foil bag with an one-way exhaust valve and kept in a constant temperature space for 8 to 24 hours. After opening the seal, you have to leave it for about 30 minutes and come into contact with the air in order to have a good flavor and moderate exhaust. In fact, different varieties of coffee roast the need for different beans and exhaust time is also different, we need to slowly understand.

Finally, it is recommended to use coffee beans that have been roasted for 7 days to 60 days. After opening, it is best to keep them in the refrigerator. The temperature in the warehouse where coffee beans are placed during the hot season should not exceed 25 degrees, and the ventilation must be good. The small warehouse can turn on the head-shaking fan to disperse the wind for a long time.
