Zhongsuo ~ Zhou ~ Zhi ~ Qian Street is a seller of coffee beans, but it is not just coffee beans. In addition to coffee beans, there are also hanging ears for sale! If you have purchased hanging ears at an offline store in Qianjie, I believe you will also have doubts about Qianjie's approach, because Qianjie insists that customers make it now, whether online or offline.

What is the problem with this approach? Offline, it is easy for customers to wait too long, but the time to make a pack of ears in the store will take about 10 minutes. Therefore, without exception, every customer and friend will ask this sentence when they buy hanging ears for the first time in an online store: "Why don't you make the hanging ears and put them away first? Wouldn't that be more convenient? "It's true that it's convenient to have ear hanging in advance, no matter who it is. However, doing so will have one consequence-shortening the period for guests to get it.

How long is the taste period for hanging ear coffee? The so-called coffee tasting period refers to the best tasting time for coffee. During this time, we can taste the most complete and richest coffee flavor of this bean. Why? Because the aroma of coffee is volatile. The coffee flavor we taste from coffee mainly comes from the aroma, and most of these aroma substances are volatile and will continue to evaporate after the coffee beans are roasted.

The speed at which coffee aroma evaporates depends on many aspects, such as the storage environment and the integrity of the structure. But as long as stored properly, the taste period of coffee beans can be as long as 2 months. It means that within 2 months, we can brew coffee with strong aroma. After 2 months, as the aroma gradually dissipated, we tasted more of its water-soluble taste from the coffee, that is, the acidity, sweetness and bitterness of the coffee. Although there is no longer a strong aroma, the coffee liquor will not taste bad, but it is just not as fragrant compared to before.

However, the taste appreciation period mentioned here on Qianjie refers to the taste appreciation period for coffee beans with complete structure. As Qianjie shared in his first tweet today, coffee beans lose a large amount of aroma when ground into powder, and because the surface area has been increased, the loss of aroma will be greatly accelerated. Qianjie had conducted an experiment before, using the coffee beans of Poquet rose summer from Qianjie bean list. The content of the experiment was to compare the flavor performance of coffee ground at different time periods.

The results show that when properly sealed, the taste period after the coffee beans are ground into powder is about one month. It is during this month that we can taste the white flowers and citrus fruits of this rose summer. After a month, these aromas became very weak, and what we tasted more was just the water-soluble taste of coffee. The production of a hanging ear coffee bag requires pre-grinding of coffee powder and then placing it into the hanging ear bag and sealing it. In other words, the taste period of hanging ear coffee is about one month. If we make and prepare the hanging ears in advance, it will mean that the tasting period for customers will be shorter after they get them. If the customer buys an ear-hanging bag made 15 days ago, the best taste period for this ear-hanging bag will be half a month left.

Therefore, in order to prevent this from happening and allow guests and friends to enjoy the complete flavor of coffee, Qianjie chose the relatively troublesome method of making it on-demand and on-demand. But if you are not in a hurry, you can also choose to place orders from Tmall and Taobao stores in Qianjie, because the factory delivers fresh coffee roasted within five days. The fresher, the longer the taste period. For friends who cannot finish it in a short time, this will be more suitable and convenient ~
