How many days does the shelf life of roasted coffee beans have to do with coffee varieties?

Buy whole coffee beans and grind them yourself. The coffee powder can last for 2 weeks. They should be stored in the same way as whole coffee beans, in an airtight container and in a cool, dry place.

Keep good coffee beans sealed as soon as possible, saying that beauty is easy to old, flowers are not red for a hundred days. The same goes for coffee beans. Coffee bean flavor is at its peak, generally lasting 3 weeks, up to a month. So we can also think that the best shelf life of coffee beans is one month

The freshly roasted coffee beans are full of vitality, reflected in the extraction of coffee, that is, the beans are very full, and they will expand when they meet water. Because the coffee is too active at this time, the oil will be rough when making Espresso, and the dissipation will be relatively fast. When coffee is extracted by hand or other utensils, the flavor is bright and mellow, and its acidity is prominent. Just like children, they are active and simple, but their emotions are not stable enough, and they are not calm enough. At this point, beans are needed. That is, freshly roasted coffee beans need to be coarse with air for a certain period of time. The length of time for raising beans depends on the roasting degree and extraction method. For lighter roasted coffee, the coffee extracted by utensils is generally raised for 1-3 days. Roast deeper, using espresso machine extraction, beans need to grow for 3-5 days.

Coffee beans show no oil/less oil/begin to secrete oil-oil secretion increases-oil shine-oil has been dried back to the coffee beans themselves-beans dry surface-continue to produce oil (this time the oily coffee is also very bad)

. The baking degree is uneven, and there are many reasons for this defect, which may be: 1. There is a problem with the design of the mixing blade of the baking machine. 2. Too little baked beans. 3. Still too much firepower. Here, I would like to advise those who want to buy a baking machine, do not buy some miscellaneous baking machines cheaply, most of the cheap baking machines have design problems with the angle of the stirring blades, and the problem of insufficient power of the exhaust motor. If you buy it, visit the forum and learn more about the pros and cons of each machine.
