What are the advantages and disadvantages of hanging-ear coffee? what are the effects of hanging-ear follicular coffee?

Daily refreshing workers who use caffeine should be no stranger to hanging-ear coffee. To hang up the ear is to grind the coffee beans into powder and put them in a sealed filter bag, which can be mounted on the wall of the cup after opening, and you can drink a delicious cup of black coffee by injecting hot water, which saves a lot of effort for busy office workers.

It is more convenient to hang earbags to make coffee.

Hanging-ear coffee is the same as the hand-brewed coffee we usually drink, and the flavor of the coffee depends on the coffee beans used. The design of the hanging-ear coffee bag comes from the lanyard tea bag. the inventors hope to simulate the hand-made dripping coffee and put the coffee powder in a non-woven filter bag in advance, and the paper on both sides of the filter bag can hang the coffee bag in the center of the cup. Because it is stuck on both sides of the cup like a small ear, so people call it "hanging ear coffee".

Brewing hanging ear coffee bag, we as long as prepare a pot of hot water, a cup can easily get a cup of mellow coffee, but also save a lot of tedious links. With the development of the boutique coffee industry, there are a variety of coffee beans on the market, such as dozens of coffee beans on the front street bean list can be made into ear bags, so hanging ear coffee not only has the advantage of convenience, but also has a very high selectivity.

Advantages and disadvantages of hanging-ear Coffee

For hand extraction, ear hanging does not need complex tools, and water injection techniques, time and proportion do not need to be strictly controlled as hand flushing, as long as you need to ensure enough hot water and appropriate proportion. But also because of the "casual" operation, the flavor of coffee is often not as rich and changeable as hand-brewed coffee. In addition, the earbag is ground into powder in advance and packed in the bag, so the aroma is not as full as the freshly ground coffee. If it is stored too long for more than a few months, it may produce some woody flavor.

In order to maximize the original flavor of coffee, the coffee powder used in hanging-ear coffee is usually ground from freshly roasted coffee beans. The coffee beans shipped in the front street are freshly roasted within 5 days. If they are made into hanging-ear coffee, when we receive them, we can usually start to brew and taste them 4-5 days after baking. Qianjie suggests drinking as soon as possible after receiving it, otherwise it is easy to lose the aroma in the coffee if it is stored for too long. If you want to taste the coffee with the fullest flavor, Qianjie suggests buying whole beans, freshly ground and flushed, with a better flavor level.

How to correctly brew hanging ear coffee bags?

The operation of hanging up the ear is very simple. The hanging ear coffee bag on the front street is made according to 10 grams per bag, which can brew out a cup of coffee liquid about 120~130ml.

Boil the water before brewing and prepare a cup or sharing pot for coffee. Tear open the sealed package, take out the coffee earbag, and tear the non-woven pocket along the dotted line above. Then pull the two ears apart, pull the whole earbag open, and hang them on the edge of the cup or sharing pot.

First of all, a small amount of hot water is injected into the first stage to wet the coffee powder and steam for about 10 to 20 seconds to help discharge the gas in the coffee powder in order to make the extraction of the latter stage more stable. 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. Inject the last section of water to full, the total amount of water injected is about 150 grams, when the coffee liquid is all filtered, that is, the extraction is over.

Before drinking in the street, you will gently shake the coffee liquid evenly, then drink it directly and taste the pure flavor of black coffee. You can add the right amount of sugar or milk according to your personal preferences.

The problems that should be paid attention to when hanging earbags.

First of all, we need to prepare enough hot water, because the temperature of the water is high enough to release more aromatic substances in the coffee powder. When brewing coffee by hand, Qianjie recommends brewing at a temperature of 86 to 93 degrees Celsius. If the temperature is only about 80 degrees Celsius, the coffee is easily bland and tasteless, while the boiling water is easy to extract the bitter taste. Because the street will open the cover of boiling water at room temperature for 1 minute or 2 minutes, let the water temperature drop slightly to about 90 degrees Celsius.

When making coffee by hand, the powder-water ratio is very important. If the powder-water ratio of 1:12 is used in a cup, the coffee is easy to be too strong and only bitter. When using 1:18, there is too much water to make the coffee plain and not enough aroma. Qianjie suggests brewing at 1:15 and injecting 150g hot water corresponding to 10g coffee powder. The flavor of the extraction is more balanced and the extraction is more stable. If you don't weigh it, you just need to find a graduated cup.

As the coffee after grinding into powder, contact with water to release soluble substances, if the use of excessive water injection is easy to make the coffee extraction uneven, the taste is also prone to defects. Qianjie recommends using a tool that can inject thin water, such as a small-nosed pot, to inject hot water smoothly and multiple times. Proper stewing will make the coffee powder exhaust gas, the extraction of the latter stage is more stable, and the flavor is better.
