Recently, because of the crazy discounts on Double Eleven, many friends have gathered online to place orders. As a result, Front Street Taobao Tmall’s customer service has received more coffee questions than before. Questions related to grinding powder, such as "How long can coffee beans be kept after being ground into powder?" and "How many days should it be best to drink the powder after grinding?" are the most frequently consulted questions among these friends recently.In fact, no matter which question it is, everyone is not asking about the shelf life of coffee powder. As we all know, the shelf life of coffee beans/powder can be up to 365 days, so everyone must be asking how long the coffee beans can be enjoyed after they are ground into powder.Maybe many friends don’t quite understand the meaning of the tasting period, so here is a brief introduction on Front Street: The tasting period of coffee beans/powder refers to their best tasting time. As long as we brew them during this period, we can get a cup of coffee with the richest flavor and the most complete experience.The reason why coffee has such a long tasting time is because the flavor we taste from it is volatile. To be precise, these aroma molecules that shape the flavor are volatile, and they will continue to evaporate after the coffee beans are roasted. When the aroma in the coffee beans/powder evaporates, the aroma of the coffee we brew from these beans will not be so rich. What we taste from it are more water-soluble flavors, such as sourness, bitterness...Therefore, in order to obtain the most complete flavor experience, many friends will strictly control the tasting time of a bag of coffee and strive to use it before the aroma is completely lost. How long does it take to enjoy coffee beans after they are ground into powder?To know the answer to this question, we first need to know the tasting period of coffee beans! The tasting period of coffee beans generally starts from the 3rd to 7th day after roasting. The specific time depends on the degree of roasting of the coffee beans. The darker the roast, the later the tasting period will start, because the darker the roast, the more carbon dioxide it contains.Excessive carbon dioxide will hinder the dissolution of flavor substances by hot water during drip extraction, which will easily make the brewed coffee not so delicious. Therefore, we usually wait a few days until the carbon dioxide content in the beans is not high enough to affect the extraction before we start brewing the beans, so that the "value" of the beans can be squeezed out more easily. It is also from this time that the beans enter the appreciation period.The tasting period of coffee beans is usually about 45 days, and the specific time will be affected by the environment and method of storage. Less exposure to negative factors during storage(e.g. fresh air, light, heat, etc.), then the coffee beans will have a longer tasting period, and the same is true for coffee powder.The tasting period of coffee powder is generally about two-thirds of that of coffee beans. If the tasting period of coffee beans is 45 days, then the tasting period of coffee powder is about 30 days. Front Street has done this kind of experiment again, that is, after roasting, the Front Street Poquette Geisha was ground into powder, sealed and packaged into several portions, and then brewed and tasted at different times in the next month.Finally, it was found that the flavor performance was good in the first three weeks after being ground into powder. Although the flavor intensity decreased every day, the citrus, floral, berry, and oolong tea flavors of Geisha were well expressed. By the 31st day, we could only taste the "coffee flavor" of the coffee itself, and the aroma was very weak. The aroma of unground coffee beans begins to weaken on the 45th day.Although this kind of experiment is not rigorous enough, we can know that the approximate tasting period of coffee beans after being ground into powder is about 30 days. The reason why the flavor loss of coffee beans will be greatly accelerated after being ground into powder is mainly because the surface area of coffee beans is expanded many times after being ground into powder, and the aroma release path is increased, so the flavor loss is accelerated.Therefore, if you choose to grind the coffee powder on behalf of others, if the consumption speed is not so fast and the coffee powder cannot be consumed in a short time, it is best to find several sealable containers for packaging and storage like Front Street did. Because every time we open the package, the coffee powder will be exposed to new air, and this new air will take away part of the aroma. Opening and closing will further shorten the tasting period of the coffee powder.In fact, it is easy to understand. I wonder if you have ever put the powder aside after grinding it. In just tens of minutes, the aroma of freshly roasted and ground coffee powder has disappeared. And this is the result of too much air contact without sealing.That’s why Front Street recommends that if you don’t drink it quickly, it’s best to use some sealed bags or cans for packaging. This can effectively prevent the loss of aroma and greatly extend the tasting time of coffee powder.
