The best drinking time of coffee beans after roasting

I think the debate between deep roasting and light roasting will last forever, because the choice of roasting degree of coffee marks the roaster's understanding of the flavor of coffee. Uncle Dou personally believes that deep roasting and light roasting do not need and should not be unified across the board. Roasters have a variety of understandings of coffee, even if they belong to the same shallow roasters, their roasting degree and curve are also different.

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".

Disposal period: calculated from the end of the "fresher period" of about 4 weeks, the quality and flavor of ripe coffee beans has been much worse than before, it is difficult to act as the word "fresh", unable to meet the picky needs of professionals. However, it is OK to make some fancy coffee, such as refreshing coffee for family breakfast, black coffee for coffee shops, or blending milk, cream, chocolate sauce, etc., which need not be denied at all. We think that this stage can last for about a month, during which time we need to open the bag and use it as soon as possible, which can be called the "disposal period".

One-way valve packaging: pouches and tins can be used. After cultivation, the coffee is put into a special vacuum container with an one-way valve, which allows the gas to go out but not in, and does not need to be stored separately, but due to the loss of aroma during the outgassing process, it avoids the formation of rotten odor, but cannot prevent the loss of aroma, because the coffee emits more than three times its own volume of carbon dioxide after roasting. If the coffee beans are in constant contact with the air at the same time, it will accelerate the fat oxidation and make the coffee taste lost. At present, the most effective method is to fill and pack with a special patented one-way exhaust valve, which can release the carbon dioxide produced by coffee internally and prevent the invasion of external air.
