Hanging coffee is ground coffee into coffee powder and packed in a sealed filter bag. The reason why it is called hanging-ear coffee, or Drip Bag Coffee in English, is because during the brewing process, the small pieces of paper (little ears) on both sides of the filter bag need to be opened and hung on the cup for extraction. Because its main feature is that you can drink a cup of black coffee very conveniently, it has become a must-have for many offices, homes and travels.

When buying hanging coffee, it is best to choose a reputable self-roasted coffee brand, so that the quality of the coffee is more guaranteed.


Front Street Coffee is an old coffee bean roasting brand. The Front Street Coffee Guangzhou offline store specializes in selling coffee beans. The store sells dozens of selected single-origin ​Pour over​(V60) coffee beans and Italian coffee beans from different coffee origins around the world. The Front Street Coffee beans are freshly roasted within 5 days. The quality of the coffee beans is stable and excellent, the price is very cost-effective, and the products are shipped within 24 hours.


If you are trying hanging ear coffee for the first time, you can start with a type with balanced taste. It is recommended to buy the following two types of Front Street Yunnan hanging ear coffee:

Altitude: 1300m
Variety: Typica
Treatment method: Sun treatment

Flavor: Sour berry aroma, nutty tonality, sweetness from brown sugar, and a tea-like aftertaste.Has the authentic Yunnan small-grained Typica flavor


In addition, since hanging ear coffee needs to be ground in advance, the coffee powder has a larger contact area with the air than the whole beans, and the aroma is more likely to be lost. Front Street recommends drinking it as soon as possible after receiving it, otherwise the aroma in the coffee will be easily lost if stored for too long. If you want to taste the coffee with the fullest flavor, Front Street recommends buying whole beans, freshly ground and brewed, for a better flavor profile.

Since the main purpose of the hanging ear is convenience, although it can be brewed using "complicated" brewing and grinding tools like ​Pour over​(V60) coffee, this also masks the convenience advantage of the hanging ear itself. And friends who buy ear-mounted coffee all like the taste of ​Pour over​(V60) coffee. In the office, at home or during travel, if there is a shortage of grinders, electronic scales, ​Pour over​(V60) pots, filter cups and other equipment, hanging-ear coffee can be used to satisfy the craving.

 

So without the help of these appliances, can ear-mounted coffee still be as good as ​Pour over​(V60) coffee?

Sharing of flushing methods


1. First of all, the net content of coffee powder in hanging ear coffee is fixed (usually 10 grams). This solves the problem of the grinder and the electronic scale.

2. The next step is to solve the water injection volume and water temperature. Just like ​Pour over​(V60) coffee, the ratio is 1:15 to 1:16, so the brewed coffee liquid should reach 140 ml to 150 ml. The water temperature should be about 90℃. If you have a thermometer or a temperature-controlled kettle, you can give priority. If not, you can roughly judge the temperature. Generally, after the kettle is boiled, turn off the heat source and open the lid, wait 2-3 minutes, and the water temperature will reach about 90℃ (room temperature is 28℃).

3. When ready, preheat the mug (water cup), take out and tear open the seal of the ear-hanging bag, open the "ears" at both ends of the filter bag, hang it on the rim of the mug, and smooth out the powder layer.

4. Inject water into the first section, just make the coffee powder layer completely wet, and steam for 30 seconds.

 

5. After steaming, add water for the second time. Use a small flow of water in a circle to fill it up. When the powder layer drops slightly, continue to add water until it is full. Repeat until the coffee capacity in the cup reaches about 140-150 ml. Then you can remove the ear-hanging bag and enjoy.

6. If you want a more precise amount of water, you can pour 150-160 ml of water into the kettle. When brewing, after filling all the water in the kettle, you can remove the ear-hanging bag when all the coffee liquid flows into the cup. The entire brewing process takes about 1 minute to complete.

 

Since hanging coffee is pre-ground coffee, the flavor will be released faster than that of whole coffee beans. Therefore, if you want to enjoy the flavor of coffee, you must consume it as early as possible.
