In addition to coffee beans, the Front Street store also sells hanging ear coffee. However, the hanging ears need to be made on site, so if a customer wants to buy a pack of hanging ears in the store, they usually have to wait for about 10 minutes without a reservation.So some guests will ask this question while waiting: "Wouldn't it be more efficient to prepare the hanging ears in advance?"Indeed, if done in advance, it can indeed increase everyone's efficiency. Front Street does not require expensive on-site production, and guests do not need to wait too long. However, Front Street still uses this less efficient method. The reason is that the appreciation period of hanging ears is relatively short.
Why does the tasting period of hanging ear coffee be shorter?First of all, we need to know that the reason why freshly ground coffee is more popular is that we can drink richer coffee flavor from freshly ground coffee. The main source of coffee flavor is the aroma generated during the roasting process of coffee beans, which is dominated by aroma and combined with other sensory experiences to associate with concrete food tastes. This is the formation of coffee flavor.However, the aroma is volatile! After the coffee beans are roasted, the aroma and carbon dioxide will continue to evaporate from the inside out. Generally speaking, the tasting period in our mouth refers to the period after the carbon dioxide evaporates to the point where it will not affect the extraction and before the aroma completely dissipates.Because during this time, we can easily dissolve the flavor substances in the coffee and brew a cup of delicious coffee with a rich flavor and full taste. Generally speaking, the tasting period of coffee beans is about two months. After two months, the aroma in the coffee beans has almost evaporated. At this time, when we brew again, we can only brew out the sour, sweet and bitter taste of the coffee itself.Without the presence of aroma, although the coffee is not unpleasant to drink, it tastes rather "stiff", "dull" and unremarkable. Therefore, under normal circumstances, everyone will control the consumption of coffee beans within two months, and then purchase freshly roasted coffee beans to replenish.But it should be noted that the two-month tasting time mentioned in front of the street is limited to coffee beans, not complete individuals that have been broken into powder. Since the surface area of the coffee beans exposed to the air is relatively small when they are intact, coupled with the physical barrier formed by the shell and tight structure, the aroma is lost very slowly.And these "flavor" effects will be completely lost after the coffee beans are ground into coffee powder! Because when the coffee beans are ground into coffee powder, the surface area will increase geometrically, and the aroma will evaporate much faster!The hanging ear coffee uses pre-ground coffee powder, so compared to the coffee beans, the tasting period of the hanging ear coffee is very short.How short is it exactly? Under the same storage conditions, the aroma loss of coffee powder is about twice that of coffee beans. In other words, if the tasting period of coffee beans is 2 months, then the tasting period of coffee powder/hanging ears using coffee powder is about 1 month. Because of this, many businesses will try every means to lock in the aroma of ear-hanging coffee!So this is why the Front Street store insists on making ear hangings first. The purpose is to reduce the loss of coffee aroma and make the tasting period longer~In order to prevent friends from misunderstanding, Front Street would like to remind you that the tasting period is not equal to the shelf life. The shelf life of coffee is as long as 365 days. After the tasting period, we can still brew it as usual, but its aroma is not as strong and it tastes a little bland, that’s all~
