Coffee friends who have bought ear hangings in Front Street stores may know that you need to wait for a while to choose a type of coffee beans to make hanging ear, because Front Street has to grind them freshly. Many friends don't understand why Front Street would rather make it on-site and let customers wait, instead of always keeping some ear-hanging coffee bags. It is more convenient and faster to buy it from the supermarket container.



A cup of delicious coffee is inseparable from good beans. Newbies should give priority to buying specialty coffee with high flavor recognition when buying coffee. Friends who like floral flavors should buy Front Street Panama Geisha coffee, which is one of the most expensive coffees in the world. If you like fresh and sour coffee, we recommend Front Street Oiran coffee. It tastes like black tea and berries. Add ice cubes and it will become an iced hand brew;

For those who like a balanced taste, that is, coffee that is neither sour nor bitter, we recommend Front Street Brazilian Semi-Sun Drying. Finally, those who pursue a solid and mellow taste are recommended to purchase the selected Front Street Golden Mandheling Coffee. This bean has been hand-selected through multiple processes to minimize the defect rate of the coffee beans, making the coffee aroma clearer and the aftertaste better. You can also add fresh milk to make a latte.

Most of the hanging ear coffee is in small packages. For example, the hanging ear bag on Front Street Street contains 10 grams of coffee powder per bag and uses a powder-to-water ratio of 1:15, so 150 grams of hot water needs to be injected. Front Street believes that the brewing of hanging ear coffee is very casual, and you can adjust it according to your favorite taste. If you want to drink stronger black coffee, you can reduce the amount of water; if you want to drink lighter black coffee, just increase the amount of water.


How long can a freshly made ear-hanging bag be kept?

Front Street has mentioned in the past that although the food safety shelf life of coffee is one year, it does not control whether the coffee tastes good or not. The key depends on how long the flavor substances in the coffee can stay. What is really worth noting is the tasting period of cooked coffee beans. Coffee brewed during this period can more fully reflect its aroma characteristics. However, this period is much shorter than the shelf life, which is generally considered to be about thirty days.

After the coffee beans are made into hanging ears, the appreciation period is even shorter. Front Street has done a series of comparisons. After using coffee beans roasted within 4 days to make hanging ears, the coffee beans will lose flavor after about 3 weeks based on the number of days from the roasting date. (PS: The flavor here refers to the specific flavor and aroma that people can associate with, and the taste of sour, sweet and bitter is still there). Anaerobic coffee can last longer, about a month. (The "ultra-long standby" of very few beans is not excluded)


Therefore, it only takes about 20 days for ear hangings to really allow you to enjoy a cup of delicious coffee. This is also the reason why Front Street insists on not pre-stocking the ear-hanging coffee and making it again when there is an order, and the specification of a pack is 10 small packs, which ensures that customers can drink it within the tasting period under the consumption of one pack per day.

Why does the tasting period become shorter after being made into ear-hanging coffee?

This involves the production method of ear-hanging coffee. Generally, the coffee beans are ground into powder first, then put into the ear-hanging bag and sealed, and finally the ear-hanging bag is placed in the outer packaging bag and heat-sealed. In this way, a small bag of hanging ear coffee is completed.

Hanging ears are pre-ground coffee. After the beans are ground into powder, the contact area between the coffee particles and the air will become larger, and the carbon dioxide and aroma substances in the body will be lost at an accelerated rate. In the end, the best tasting period of hanging ear coffee will be shortened.


Friends who have bought dark-roasted bean ear bags may have noticed that the ear bags are still flat when they are first received, but after being left for a period of time, they become bulging. This is actually the loss of carbon dioxide and flavor and aroma.

Therefore, when making ear-hanging coffee on-site in Front Street, we will try our best to increase the speed, shorten the contact time between coffee powder and air, and reduce the loss of flavor. And coffee lovers should finish tasting as soon as possible when drinking.
