How long can lightly roasted and moderately and deeply roasted coffee beans be stored?

If we buy coffee beans, we will finish them in the shortest possible time, but if we can't finish them, do you know how to store them, and for how long? After the coffee beans are roasted, the oxidation and aroma volatilization is irreversible, so we should pay attention to the preservation of beans. Because of too much carbon dioxide, various flavors of freshly roasted coffee beans cannot be fully released, and they are tasteless to drink. So beans are not as fresh as possible. It takes a period of time to do "exhaust", which is also known as raising beans. Most of the beans can be drunk after 24 hours. We know that coffee beans have the best flavor period after baking, which is usually called the best flavor period after the beans have been cultivated (about 24-48 hours) until there is an obvious defective flavor.

So is it true that all coffee beans have the same shelf life? in fact, it is not, because coffee is roasted in shallow, medium and deep roasting, and the storage period of different roasted beans is also different. If it is shallow roasting, such as Yega Xuefei of Qianjie Coffee and Sidamo Fakui Coffee, it is about 40-50 days, the best flavor period for moderately roasted beans is about 30 days, and the best flavor period for deep roasting is shorter. Such as Blue Mountain Coffee is usually within 30 days, the best flavor period is established under certain preservation conditions, that is, the preservation of ripe beans of the three key factors: sealing, protection from light, moisture.
