Based on the reasons of food safety, the shelf life of coffee products is one year according to the relevant food laws of our country. In fact, if you want a good cup of coffee, Qianjie coffee is recommended to be finished as soon as possible. Coffee fans who often buy coffee beans in the front street know that the taste period of coffee beans is 30 days, which means that we can drink the flavor of coffee within a month. after all, the aroma of coffee is a natural fluid, and the aroma will become less and less as time goes by. After the coffee is ground, it will be lost more quickly. Of course, if you just use coffee as a reminder, you can use it up within a year.

What is a hanging-ear coffee?

The origin of hanging-ear coffee is that with the development of economy, the pace of life begins to accelerate. Many coffee fans who have become office workers do not have much time to make coffee by hand. If you go to make coffee by hand in a hurry, the coffee will definitely taste bad. So hanging-ear coffee was born.

And according to Qianjie, it was Yamanaka Industrial Co., Ltd. in Japan that used the concept of tea bag in coffee, invented filter-hanging coffee and applied for a patent. However, the earbag designed by Yamanaka Industry can not bear the weight of brewing coffee, and it is easy to lose balance in the brewing process, so it has not been commercialized successfully. It was not until 1998 that Daji improved the original invention and extended the ear-hanging part to the outside that today's hanging-ear coffee came into being.

And most of the coffee fans who come to Qianjie store to buy hanging-ear coffee are also working parties. with the support and demand of coffee-loving friends, Qianjie has also begun to develop some individual coffee beans suitable for making hanging-ear coffee for coffee fans in Qianjie to taste, such as Honduras Litchi orchid coffee beans and Shirley coffee beans, which are the most popular coffee fans in Qianjie recently. Qianjie turned them into hanging-ear coffee. But some coffee fans who make hanging-ear coffee for the first time have doubts about how to brew it correctly, so let's demonstrate how to make hanging-ear coffee correctly in Qianjie.

The correct brewing method of hanging-ear coffee

1. Warm cup

When you are ready to brew the cup of hanging-ear coffee, first pour in some warm cups of hot water. The effect is that the brewed coffee will not cool down too fast, because as the temperature drops, the coffee will produce a different flavor, that is, a hierarchical sense of flavor, so if you cool down too fast, you will miss many different tastes.

two。 Water temperature

The temperature of the brewed water is very important. It is recommended that the temperature be between 85 and 90 degrees. If the brewed coffee is too bitter, try to lower the water temperature. On the contrary, if it is too light or too astringent, it can increase the water temperature, but the range should still be between 85 and 90 degrees.

3. Hang up the back edge

First shake the earbag slightly to let the coffee powder fall to avoid the coffee powder being scattered when it is torn open, then pour out the hot water from the cup, tear open the seal on the earbag, extend the paper ears on both sides, and shake so that the coffee powder is smooth, and finally hang to the edge of the cup.

4. Pre-wet hanging ear coffee bag

The first time you inject water, you should inject just the right amount of soaked coffee powder, too much or too little will affect the flavor, and then wait 20 seconds for the coffee powder to fully absorb water. The thickness of the coffee can be adjusted by pre-wetting time, which can be extended to 40 seconds to get stronger coffee.

5. Water injection

The second injection of water can be poured to the filter paper eight full, it is best to use a slender flow, wait until the flow down to the pre-wet height, you can continue to fill water to the full, until quenching out of 150 to 180cc so far, once quenching is finished, do not need to wait for all the water in the filter paper to flow out, just throw it away.

Why should we make hanging-ear coffee correctly?

Qianjie thinks that some coffee fans may wonder why hanging-ear coffee can't be soaked directly like a tea bag. In fact, this is about fine coffee. Coffee fans who have drunk fine coffee all know that excessive extraction in the process of hand-brewing will make the coffee bitter, so it is necessary to simplify the brewing time. Hanging-ear coffee is actually a portable version of fine coffee. It itself is to make the ground coffee powder into a powder bag, but it saves the step of letting coffee fans grind themselves, so assuming that there is no proper brewing of hanging-ear coffee, the flavor is also bad.

Notes for brewing hanging-ear coffee:

1. Do not repeat brewing.

two。 Do not continue to soak the coffee powder in the cup after flushing, otherwise it will be over-extracted.

3. Although it is convenient to throw the hanging-ear coffee directly into the cup, the water temperature begins to drop before the hot water is completely soaked in the powder bag, which will lead to insufficient coffee extraction and affect the taste and flavor of drinking.

The best taste period of hanging-ear coffee

As mentioned above in the front street, hanging-ear coffee bags are actually fine coffee ground into coffee powder in advance, and the shelf life should be about the same, but in fact, the taste period of hanging-ear coffee will be shorter than that of coffee beans. generally speaking, it needs to be finished within two weeks after the coffee beans are made into hanging-ear coffee, this is because the production of hanging-ear coffee first grinds the coffee beans into powder, which increases the surface area of the coffee in contact with the air. Preservation is even more difficult, and within two weeks, you can fully drink the original aroma of coffee, but this requirement is only for coffee fans who have requirements for flavor, if you do not have too high requirements for coffee aroma and flavor, in fact, if you finish it within a year, the coffee beans will not go bad.

According to Qianjie practice, even using vacuum packaging can not restrain the disappearance of coffee flavor, because carbon dioxide will be released from the moment the coffee beans are baked. Therefore, careful coffee fans will find that the packaging will be a little bulging when they receive the hanging-ear coffee mailed in the front street, which means that the packet of coffee is packaged when it is fresh. Therefore, when coffee fans get it, it is the best time to enjoy it.

When the carbon dioxide in the coffee is released (about two weeks), the aroma will begin to be released, and there is no change on the surface, but the coffee has gradually deteriorated and has been placed at room temperature for more than two weeks. The aroma of the coffee is probably left, but because the earbag is sealed, it can still be smelled when it is opened, but it is not so fragrant after brewing. That's why Qianjie advises coffee fans to taste the best flavor of the coffee within two weeks after receiving it.

So coffee fans can see that the packaging of many coffee beans will be equipped with breathable valves in the coffee market, so that the carbon dioxide of coffee can be released to prevent the packaging from breaking due to the expansion of carbon dioxide. On the one hand, it can prevent a large amount of air from entering. But many unknown coffee fans will squeeze the breather valve to test the taste, but it actually shortens the life of the coffee when squeezing out the fragrance. Therefore, even if the ear bag is equipped with a breathable valve, it is not only costly, but also unable to prolong its best taste period.

How to choose hanging ear Coffee

Then how to choose hanging ear coffee? As the article in the former street said, hanging-ear coffee is actually fine coffee ground into powder, so coffee fans can choose according to their favorite single-item coffee. For example, the front street Panamanian butterfly coffee beans or Honduran sherry coffee beans and other front streets can help make hanging-ear coffee for coffee fans to choose, so if you are also eager to drink coffee at work, you can try hanging-ear coffee!

The above is the relevant information about hanging-ear coffee in Qianjie, hoping to help coffee fans who want to know about hanging-ear coffee.
