Shelf life of roasted coffee beans-pros and cons of drinking coffee

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 period".

There is basically a general tendency to bake through long-term experience. Then do a standard rhythm baking, and finally reach the second explosion dense stage, in which each small stage (for example, the end of the first explosion and the beginning of the second explosion), take about 20g of beans with a sampling spoon (the action above). Put it in the cup to cool down, so as to get several bean samples with different baking characteristics for blind test (the state below), and get a taste dominant baking degree in the blind test. Do another quick stir-fry to compare the standard speed to see which is better. If you think the standard rhythm is better, you may also experiment with a slow stir-fry, and basically you will find the baking rhythm and baking degree to be selected at last.

Fresh beans are suitable for sealing and preservation in a bag with an one-way exhaust valve. be sure to empty the air in the bag as much as possible after use, and then keep it sealed. Usually put beans in a cool and ventilated cabinet, as long as it is not close to the heat source is not a big problem. If it's not for special reasons, don't put beans in the fridge! Keep it in a cool place at room temperature. Because the low temperature of the refrigerator will bring condensed water to the package. This is the sweet coffee! If you really don't have time to drink, but the beans are very good, those you don't want to throw away can be frozen in the freezer and thaw later. Although the flavor will certainly be greatly damaged, it is better than throwing it away.
