The method of brewing high-quality hanging-ear coffee to illustrate how to make a good brew of filter coffee.

With the deepening of coffee culture in recent years, many "morning shift workers" have to drink a cup of coffee every day in order to have the energy to "carry bricks." However, not everyone can go to the coffee shop at any time every day to taste a delicious cup of hand-brewed coffee, so for convenience, people invented hanging-ear coffee.

What is hanging-ear coffee?

Hanging-ear coffee is to grind the coffee into powder in advance and put it in a sealed filter bag with two ears that can hang and stabilize. Coffee bags can be brewed anytime and anywhere as long as hot water and a container of coffee are needed.

Hanging ears and hand brewing belong to filter extraction, but compared with the operation of hand brewing coffee, hanging ears will be much more convenient and faster. Hand coffee at least need to prepare: brewing kettle, thermometer, filter cup and filter paper, grinder, chronograph, etc., because the ear is ground in advance, there is no need to be equipped with grinding equipment. The filter bag is usually made of degradable non-woven fabric, and the soluble matter extracted by water from the coffee powder can be oozed through the non-woven fabric, so there is no need to prepare filter paper and filter cup.

How do you make your coffee?

Usually, the hanging-ear coffee on the market is mostly in small packages, such as the hanging-ear bag in the front street is 10g / packet of coffee powder, using the ratio of 1:15 powder, so it needs to be injected with 150g of hot water.

First of all, we need to prepare a container for coffee, either a sharing pot or a drinking cup; a kettle for filling water.

First tear open the sealed package, take out the coffee earbag, and tear the non-woven pocket along the dotted line above.

Pull both ears apart, pull the whole earbag open, and hang them on the edge of the cup or sharing pot.

First, wet the coffee powder in the first stage and steam for about 10 to 20 seconds. The second stage of small water is injected smoothly until the liquid level is close to full, waiting for the coffee liquid to drop until the coffee liquid runs out. Pour the last section of water to the full. when the coffee liquid has been dripped and filtered, shake it gently and start to enjoy it.

What do you need to pay attention to in the ear-hanging coffee?

Similar to hand brewing, the taste of hanging-ear coffee depends on coffee beans, and different producing areas and treatments have different flavor tonality. What is different from hand flushing is that the coffee powder that hangs the ear has been ground in advance, so the aroma is not as full as that of current grinding.

After the coffee beans are ground into powder, the area of contact with the air is more, and the loss of gas and aroma substances in the body will be accelerated, which means that the appreciation period is shortened, and the aroma of the coffee is not so rich and tasteless. If it is kept for too long, the coffee powder will be aged and there will be a "woody smell".

Therefore, we need to pay attention to the freshness of the coffee when we buy it. Qianjie shipped coffee beans are freshly baked within 5 days, can also be made into ear bags, 20 yuan / 100g processing cost. Everyone should drink it as soon as possible after buying it, and the coffee in the best taste period has the best flavor.

The water temperature of brewing is also very important. usually, the water temperature of our hands should be controlled at 86-93 degrees Celsius. If the water temperature is too low, the extraction efficiency of coffee will be slow, and it is easy to underextract. If you can't increase the water temperature, lengthen the contact time between the coffee powder and the hot water, that is to say, soak a little longer.

The amount of water injected and the size of the flow can also change the concentration of hanging-ear coffee. Qianjie recommends that the ratio of powder to water be controlled at 1:15, and then adjust up and down according to your favorite concentration. In addition, the injected water is too fast, the extraction time of coffee powder is short, and the taste of coffee is easy to be light, so it is best to use a steady small flow throughout the whole process to make the extraction of the powder layer more uniform.
