Among all the convenient and fast freshly brewed coffee, hanging ears are undoubtedly the "ceiling" for cost performance. It does not require complex equipment or high technology. You can get a full aroma of coffee with a cup, water and hands.

But sometimes it's just the same. Some people soak it out as pale as water, some rush out bitterness, and some make it close to the level of hand-washing... I believe many people want to know what the difference is between them and what the reason is.

So Qianjie is here today to answer some of the most concerned questions, hoping to comprehensively solve your doubts about Guar Coffee.

A. What should I pay attention to in "hanging" and "rushing"?

Formally, the hanging ear simulates regular hand-brewed coffee extraction, so its drip mode should be restored as much as possible when brewing. When selecting a cup, give priority to using a tall container, which can prevent the cup from soaking in the paper shells on both sides because it is too shallow. Even the filtered coffee liquor will go back to re-extract the powder layer, which will eventually lead to the lack of layering in the coffee., and with a jumbled taste.

If a cup with a wider diameter is used, when the ears on both sides are directly pulled open and stuck on the edges, the filter bag can easily fall down because it cannot bear the weight. You can fold inward along the two dotted lines on the cardboard to form a pair of "square wings" on the left and right ears, which will increase the leverage of the filter bag on the cup.

B. Is a hand-flushing pot a necessity? How should I rush without it?

In many tutorials on flushing ears (including Qianjie Articles), a hand-flushing pot with a thin spout is used for water injection. Many people naturally think this is an indispensable tool. In fact, this is not the case. Because of the design of the filter bag, there is no need to inject water around the hanging ears. The equipment used to flush the hanging ears basically does not have many limitations. To put it bluntly, it is enough to pour water. Therefore, Qianjie believes that if we only pursue efficiency, there is no need to spend a lot of money to buy a special hand-brewed pot to wash ears.

However, it should be noted that appliances such as boiling water pots and thermos cups that are difficult to control the water flow tend to vary between large and small when pouring water, resulting in uneven extraction of the entire cup of coffee. Qianjie recommends injecting the total amount of water into multiple and small amounts, and raising the water injection point as much as possible when injecting water, which can prolong the extraction time and make the coffee more full.

C. Do you need to steam for the first stage of water injection?

When flushing with your hands, the action of wetting the powder layer is first called "steaming", which can help expel excessively active carbon dioxide, thereby extracting flavor substances more efficiently. But for pre-ground hanging ear coffee, it's a different story.

First of all, fresh hanging ears should be steamed. Front Street. The hanging ear coffee is freshly roasted within 5 days and is freshly ground and made after ordering. Under the condition of normal logistics and transportation, the hanging ear bag is still in a state of abundant gas when we arrive. In order to avoid these gases from affecting the extraction, we can first Pour in one-third of the bag of hot water to moisten the coffee powder, observe the bubble situation, and wait until the bulging bag no longer becomes bigger (about 20 seconds) before starting to inject the second paragraph.

But if the production time of hanging ears has exceeded 10 days, which means that most of the carbon dioxide should have been lost, then steaming becomes an unnecessary step. If the first section is poured into the water powder layer and the water powder layer is directly recessed, it means that there is not much gas left in it. You can directly inject the second section and consume the remaining hanging ears as soon as possible; but if the powder layer still shows slight signs of bubbling, You can wait for 10 to 15 seconds before continuing to inject water to allow the powder layer to vent a little.

D. Why is there no foam when injecting the second section of water?

Just like the previous steaming, the amount of foam depends on the freshness of the coffee. The fresher beans used, the more foam there will be. When left for more than half a month, basically no foam will be visible in the first paragraph.

However, if the hanging ear is fresh, the foam will "disappear" when the second stage is filled with water, which is likely to be due to the light baking degree.

For example, when brewing on the same date as production on Qianjie. Huakui Guar Coffee and Qianjie. Manteine hanging ear coffee, the foam amount of medium and deep roasted Manteine is very dense, showing the strong flavor of caramel, spices, and roasted nuts, while the foam of medium and light roasted flower is very sparse, and the flavor is rich. Fruit, dried mango, black tea aroma. It can be seen that the amount of foam can help us judge the freshness and roasting degree of the ear, but it has no direct relationship with the taste of coffee.

E. It's too wasteful to soak it only once. Can I soak it for a second time?

No matter which brewing method is used, the soluble flavor substances of coffee are gradually released from strong to light. Once the ratio is determined, the concentration and taste of the coffee will be confirmed. The rest in the coffee powder is some lighter, even a woody, dull macromolecular substance, if brewed for a second time, will definitely not be as good as the first time.

However, since many people reported that "it was too wasteful to soak only one cup of hanging ears" and wanted to know if they could extract it twice, Qianjie tried to rinse the washed hanging ears again. The coffee obtained was greatly discounted in terms of color, concentration, aroma and taste, but it actually did not have an unpleasing taste to drink, so if you don't mind this kind of situation, it's not impossible to make an extra cup.

F. The taste of hanging ear coffee is too weak. What should I do?

Due to various limitations, it is often difficult for hanging ears to grasp the extraction like hand-brewed coffee. Especially due to the limitations of filter bags and water injection conditions, coffee powder and hot water are prone to insufficient contact, so the comparison is "bitter" and the feedback is too weak. People account for the majority.

Combined with Qianjie's brewing experience, the weak taste of Guar coffee is mainly related to insufficient temperature, too much water, and too short extraction time. For specific solutions, you can refer to Qianjie's article "5 small details to make Guar double it delicious!!".
