How long can the roasted coffee beans be stored-Italian concentrated introduction

The classification of these three baking methods is only a very general method. In fact, the baking depth is affected by many factors, such as the style of the bean baker. This answer is only a general statement, the barista will adjust the baking curve according to the characteristics of each bean, and the flavor of each bean will be different from that of a pot with a difference of one degree or 2 seconds. and the flavor performance is very rich, flower fragrance fruit acid some tea flavor is this kind of bean flavor expression. On the other hand, medium baking is a more balanced expression with both refreshing flavor and thick taste. Deep-baked beans are more similar to his taste, and their flavors are usually strong, such as smoke, chocolate and woody flavor. And it will be accompanied by a thick taste, if your guests like round, mellow and sweet coffee, then medium or even deep roasting is more appropriate. But Uncle Dou wants to say a word for the roasters who roast coffee deeply. Many roasters with light roasting style think that when coffee is roasted deeply, there is no other flavor except bitterness in the coffee, and the flavor of coffee is lost in deep roasting. This statement is not objective. A roaster who is good at deep roasting coffee, not only is there no burning smell in his coffee, but the guests can also feel the flavor of the coffee. In other words, he will only bake coffee to black oil, and the smell of smoke and coke is extremely strong, he is not a baker, but a charcoal burner.

Fresh period: from the end of the "fresh period" of about 2 weeks, the coffee beans in the bag gradually go down from the peak state. However, if it is properly preserved, the quality and flavor of coffee beans decline slowly in the first period of time, and the freshness of coffee beans is still at a high level. We call it a "relatively fresh period" for about one month. Every coffee lover and coffee shopkeeper should strive to use up the coffee beans purchased before the end of the "fresh 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 believe that this stage can be maintained 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".

The total 10-week period from the latest fresh period everywhere is neither long nor short, and consumers should make good use of it. For coffee cooked beans that have passed the disposal period, even if the bags have not been opened, the flavor is sharply reduced, the freshness is gone, and there is no taste value. This problem is distressing, because for any ordinary coffee consumer, there is absolutely no ability and technical means to achieve good storage of coffee powder, and test data from professional institutions show that coffee beans will escape nearly 50% of the active volatile aromatic substances within the first 5 minutes of grinding. If you buy coffee powder (except filled with inert gas), do not expect too much on the taste and flavor, can only talk about convenience as the starting point. And buying the worst grinding equipment will be hundreds of times better than buying coffee powder directly, enthusiasts should settle down to learn how to grind coffee beans.
