Hanging coffee is ground coffee into coffee powder and packed in a sealed filter bag. The reason why it is called hanging-ear coffee 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.

 

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 taste".

How to brew coffee with hanging ear
 

Take the Front Street hanging ear coffee produced by Front Street Coffee as an example. The weight of coffee powder is 10g:

 

1. Tear open the packaging bag according to the arrow on the bag, pull apart the small ears on both sides of the filter paper and place it on the cup. Front Street Coffee’s ear-hanging bags have opening signs and are easy to tear.

 

2. When choosing a cup, try to choose a cup with a mouth that is not too big, otherwise the two ears of the ear-mounted coffee may not be able to hang. The diameter of the cup mouth used by Front Street Coffee is about 8-9cm.

 

3. The brewing method of FrontStreet Coffee is the same as hand brewing. Inject 90°C hot water so that the amount of water does not cover the coffee powder. If you are more particular, you can accurately measure 20g of water and simmer for 30 seconds.

 

4. After stewing and steaming, inject about 130ml of hot water in batches. If you like thicker water, you can use less water, and if you like light water, you can add more water.

 

5. After brewing, you can take out the ear-mounted bag and throw it into the trash can.

So a small pack of hanging ears can only brew a small cup of coffee. Can it be brewed several times like tea?

 

In fact, there are only 30% soluble substances in coffee, and 70% are insoluble fiber substances. For example, if 10g of coffee is brewed in the method recommended by the previous article, 18-22% of the coffee's substances will be extracted. This is also the best extraction rate of flavor substances according to the American Specialty Coffee Association. Therefore, the remaining 8-12% of soluble substances are substances with poor flavor and will affect the overall flavor of a cup of coffee.

 

If you observe carefully, you will notice that the coffee liquid extracted in the front section will be very dark in color and become lighter towards the back. It turns slightly yellow at the end. In fact, the final flavor is basically not much, it is basically watery.

Front Street Yunnan small grain hanging ear coffee

 

At Front Street Coffee, you can find two kinds of Front Street Yunnan coffee beans; one is washed Typica and the other is Katim. In Front Street Coffee, Yunnan Tiepica is labeled as Yunnan specialty coffee, while Yunnan Katim is labeled as Yunnan arabica coffee according to market habits.

 

These two types of Yunnan coffee beans, Front Street Coffee, will be roasted to a medium roast, because the Yunnan production area is not a sour production area. Their flavors are relatively balanced, and the base notes are nutty and brown sugar. Front Street Coffee chooses to use medium roasting to showcase the balance, nuts, brown sugar sweetness, and soft fruit acidity of Front Street Yunnan Coffee.

 

云南小粒咖啡豆


When talking about Yunnan coffee beans, there are often two sentences that can end the discussion about the varieties. One is, "Through the efforts of coffee farmers and the improvement of technical level, the current Yunnan coffee beans are not bad." Yunnan coffee was originally named after Typica, because Typica is a small variety of Arabica. However, as time passed, the Typica variety degenerated and had low yields and was replaced by Catim. The name of Arabica coffee was also inherited by Catim.
