Food has a shelf life, and coffee beans usually have a shelf life of one year, but for those who pursue high-quality coffee, that is obviously not enough. how long is the life cycle of coffee bean flavor? Is the coffee bean as fresh as possible? Friends who like red wine all know that good red wine needs to be opened an hour in advance to oxidize the red wine, which will be more conducive to the release of aroma. Although the principle is different, coffee does have a similar practice, which we call bean cultivation.

Storage and cultivation time of freshly roasted coffee beans:

Young-newborn calf

The coffee beans that have just been baked are full of vitality, which is reflected in the extraction of coffee, that is, the soy gas is so abundant that it will swell at the slightest encounter with water. Because the coffee is too active at this time, the oil will be rough when making Espresso and dissipate relatively quickly. When using hand-made or other utensils to extract coffee, the flavor is bright but not mellow, and its sour taste is prominent. Just like people in childhood, they are active and simple, but they are not emotionally stable and calm enough. You need to raise beans at this time. That is, freshly roasted coffee beans need to be thickened with the air in a certain period of time, and the time of raising beans depends on the baking degree and extraction method. For coffee that is roasted shallower and extracted with utensils, it is common to raise beans for 1-3 days. The deep-baked ones, which are extracted by Italian coffee machine, need to raise beans for 3-5 days.

Young and middle-aged-when drinking

The coffee beans raised are sealed and preserved as soon as possible. It is said that beauty is easy to grow old, and flowers are not red for a hundred days. The same is true of coffee beans. The flavor of coffee beans is at its peak, which usually lasts for 3 weeks, up to a month. So we can also think that the best shelf life of coffee beans is one month.

Recession-the late twilight of heroes

Which will be more attractive, a former beauty in her seventies or eighties or a 28-year-old cardamom girl? The flavor and aroma performance of a good coffee in recession may not be as good as that of ordinary coffee in its prime. Therefore, when we choose and buy coffee beans, we should not only look at the brand and origin, but also the production date (fresh roasting) and bean seeds are more important references.
