With the development of the boutique coffee market, many coffee fans will study how to make a good cup of coffee by hand, but as office workers, it is impossible for coffee fans to carry all the equipment for brewing coffee, so Qianjie Coffee has launched hanging-ear coffee. The purpose is to let coffee fans who do not have time to make their own coffee can drink a cup of delicious coffee after work. Then the next article will come to the front street to popularize science and find out what is hanging-ear coffee.

What is hanging-ear coffee?

Hanging-ear coffee is a portable coffee that grinds coffee beans into powder and puts them in a sealed filter bag. In the process of brewing this filter bag of coffee, the small pieces of paper on both sides of the filter bag need to be hung on the wall of the cup for brewing and extraction, so it is named hanging ear coffee.

According to Qianjie, the creator of hanging-ear coffee is Yamanaka Industrial Co., Ltd., Japan. They applied the concept of tea bag to coffee, so they invented filter-hanging coffee and applied for a patent. However, the hanging-ear bag they designed could not bear the weight of brewing coffee, and it was easy to lose balance in the brewing process, so Yamanaka industry did not succeed in commercializing it at that time.

It was not until 1998 that Daji Corporation of Japan improved the original invention and extended the ear-hanging part to the outside, so that the filter bag could withstand the weight of brewing coffee, and hanging-ear coffee began to be widely spread among office workers who liked individual coffee at that time.

How many times can I make coffee with hanging ears?

As Shangqianjie Coffee said, hanging-ear Coffee uses the concept of tea bag, but what Qianjie Coffee wants to emphasize is that hanging-ear coffee can not be soaked in water all the time like tea bag, or it can be brewed repeatedly. These are all the wrong methods of making hanging-ear coffee.

Because hanging-ear coffee is actually grinding individual coffee beans into powder and putting them in a sealed filter bag, it just saves coffee fans the step of grinding them with coffee grinders themselves, so it is essentially the same as the coffee powder used in hand-brewed coffee, but it cannot reach a precise level in terms of time and equipment.

Coffee fans who know about hand-brewed coffee in front of the street all know that the process of hand extraction is only two minutes. If the extraction time is too long, it will over-extract and affect the flavor of coffee. So coffee fans who have come to Qianjie Cafe to taste hand-brewed coffee all know that baristas will directly throw away coffee powder with filter paper after hand extraction, let alone reuse it.

Therefore, the use of hanging-ear coffee must not be repeated brewing, otherwise the extraction is not good substances in coffee beans, which will not only affect the flavor of coffee, but also affect health. Next, Qianjie Coffee, let's list a few points for attention when making hanging-ear coffee.

Matters needing attention in making 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. Can not directly put hanging ear coffee into the cup, although it is very convenient, but before the hot water completely soaked the powder bag, the water temperature began to drop, which will lead to insufficient coffee extraction and affect the taste and flavor of drinking.

How to make hanging-ear coffee correctly

The above Qianjie coffee gives coffee fans some tips on how to make hanging-ear coffee, and then Qianjie coffee will take you through the correct process of making 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.

The best taste period of hanging-ear coffee

Another point is that the hanging-ear coffee must be used up within two weeks, because the production of the hanging-ear coffee is first to grind the coffee beans into powder, which increases the surface area of the coffee in contact with the air, and it is even more difficult to preserve it, and within two weeks, can fully drink the original aroma of coffee, but this requirement is only for coffee fans who have requirements for flavor. If there is no high requirement for the aroma and flavor of the coffee, in fact, the coffee beans will not go bad after drinking it within a year.

In fact, it is difficult to make the appreciation period of hanging-ear coffee longer. 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. 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 the coffee parcels sent by Qianjie Coffee, they will find that the hanging-ear coffee they get is the best time to enjoy it.

How to choose hanging ear Coffee

The above Qianjie coffee has given coffee fans some knowledge about hanging-ear coffee, but there are often coffee fans who have just come into contact with hanging-ear coffee and asked how to choose hanging-ear coffee. In fact, as the article in the front street said, hanging-ear coffee is a single coffee bean ground into powder to make a filter bag, so you can choose according to your favorite single coffee, such as Indonesia Mantenin. Brazilian Queen Manor, Honduras Shirley and other front street coffee can help coffee fans to make hanging-ear coffee bags.

The above is the relevant knowledge about hanging-ear coffee sorted out by Qianjie Coffee. I hope coffee fans who read this article can have a deeper understanding of hanging-ear coffee and choose the coffee beans that best suit their own taste.
