For food safety reasons, my country’s relevant food laws stipulate that the shelf life of coffee products is one year. In fact, if you want to drink a good cup of coffee, FrontStreet Coffee recommends drinking it as soon as possible. Coffee fans who often buy coffee beans on the front street know that the tasting period of coffee beans is 30 days, which means that we can drink the flavor of coffee within a month. After all, the aroma of coffee is a natural liquid, and the aroma will become less and less as time goes by. After the coffee is ground, it will dissipate faster. Of course, if you just use coffee as a reminder drink, you can use it within a year.
What is hanging ear coffee?
Hanging ear coffeeThe origin of coffee brewing is that as the economy develops and the pace of life begins to accelerate, many coffee fans who have become office workers do not have much time to brew coffee by hand. If they brew coffee by hand in a hurry, the coffee brewed will definitely taste bad, soHanging ear coffeeAnd so it was born.
And according to Front Street, it was originally Japan's Yamanaka Industrial Co., Ltd. that applied the concept of tea bags to coffee, invented filter-hung coffee and applied for a patent. However, the ear-hanging bag designed by Yamanaka Industrial Co., Ltd. could not bear the weight of brewing coffee, and it was easy to lose balance during the brewing process, so it was not successfully commercialized. It was not until 1998 that Daji Shoji improved the original invention and extended the ear-hanging part outwards, and today's ear-hanging coffee was born.
Most of the coffee fans who come to the Front Street store to buy hanging coffee are working people. With the support and demand of coffee fans, Front Street has also begun to develop some single-origin coffee beans suitable for making hanging coffee for Front Street coffee fans to taste. For example, Honduran lychee orchid coffee beans and sherry coffee beans, which are the most popular among FrontStreet Coffee fans recently, Front Street turned into hanging coffee. However, some coffee fans who are brewing ear-mounted coffee for the first time are confused about how to brew it correctly. Then Front Street will demonstrate how to brew ear-mounted coffee correctly!
The correct way to brew ear-mounted coffee
1.warming cup
To prepare the cup for brewing ear-hanging coffee, first pour some hot water into the cup to warm it. The function is to prevent the brewed coffee from cooling down too quickly, because as the temperature drops, the coffee will produce different flavors, that is, the layering of flavors. Therefore, if the temperature is cooled down too fast, many different tastes will be missed.
2. Water temperature
The temperature of the brewing water is very important. The recommended temperature is between 85 and 90 degrees. If the brewed coffee is too bitter, you can try lowering the water temperature. On the other hand, if it is too bland or astringent, you can increase the water temperature, but the range should still be between 85 and 90 degrees.
3.Hang the back edge
First, shake the ear-hanging bag slightly to let the coffee powder fall down to avoid scattering the coffee powder when tearing it open. Then pour out the hot water in the cup. After tearing off the seal on the ear-hanging bag, open the paper hanging ears on both sides, shake it to make the coffee powder flat, and finally hang it to the rim of the cup.
4.Pre-wetHanging ear coffee bag
When injecting water for the first time, you should inject just enough water to soak the coffee powder. Too much or too little will affect the flavor. Then wait 20 seconds for the coffee powder to completely absorb the water. The intensity of the coffee can be adjusted using the pre-wet time, extending to 40 seconds can result in stronger coffee.
5.Inject water
For the second time, water can be poured into the filter paper until it is 80% full. It is best to use a slender water stream. After the water flow reaches the pre-wetted height, you can continue to pour water until 150 to 180cc is quenched. Once the quenching is completed, there is no need to wait for all the water in the filter paper to flow out, and it can be discarded directly.
Why brew correctlyHanging ear coffee
Front Street thinks that some coffee fans may wonder why hanging ear coffee cannot be soaked directly like tea bags. In fact, this has to talk about specialty coffee. Coffee fans who have drank specialty coffee know that over-extraction during the hand brewing process will make the coffee bitter and unpalatable, so it is necessary to The brewing time is simplified, and the hanging ear coffee is actually a portable version of specialty coffee. It itself is made of ground coffee powder into powder packets, but it saves the step of letting coffee fans grind it by themselves. Therefore, even if the hanging ear coffee is not brewed correctly, the flavor will be bad.
Precautions for brewing ear-mounted coffee:
1. Brewing cannot be repeated.
2. Do not continue to soak the coffee powder in the cup after brewing, otherwise it will be over-extracted.
3. It is very convenient to throw the hanging coffee directly into the cup, but before the hot water completely soaks the powder bag, the water temperature begins to drop, which will lead to insufficient coffee extraction and affect the taste and flavor of the drink.
The best period to enjoy hanging ear coffee
As mentioned in Front Street above, hanging coffee bags are actually specialty coffee ground into coffee powder in advance, so the shelf life should be about the same. However, in fact, the tasting period of hanging coffee is shorter than that of coffee beans. Generally speaking, after the coffee beans are made into hanging coffee, it needs to be consumed within two weeks. This is because the making of hanging coffee first involves grinding the coffee beans into powder. , which also increases the surface area of the coffee in contact with the air, making it more difficult to store. Only within two weeks can you fully drink the original aroma of the coffee. However, this requirement is only for coffee fans who have requirements for flavor. If you do not have high requirements for the aroma and flavor of coffee, then in fact, if you drink it within a year, the coffee beans will not deteriorate.
It is actually very difficult to extend the tasting period of ear-hanging coffee. According to the practice of Front Street, even the use of vacuum packaging cannot prevent the disappearance of the coffee aroma, because carbon dioxide will be released from the moment the coffee beans are roasted. Therefore, careful coffee fans will find that the packaging will be a little bulging when they receive the ear-hanging coffee mailed by Front Street. This means that the bag of coffee was packaged when it was fresh, so coffee fans will get it during the best tasting period.
When the carbon dioxide in the coffee is released (about two weeks), it will begin to release the aroma. No change can be seen on the surface, but the coffee has slowly deteriorated. If it is left at room temperature for more than two weeks, the aroma of the coffee will probably be gone. However, because the ear-hanging bag is a sealed package, you can still smell the aroma when you open it, but it will not be so fragrant after brewing. That’s why Front Street recommends that coffee fans drink the hanging ear coffee within two weeks after receiving it to enjoy its best flavor.
Therefore, coffee fans can see that many coffee bean packages in the coffee market are equipped with ventilation valves. The purpose is to release the carbon dioxide of the coffee to prevent the packaging from rupturing due to the expansion of carbon dioxide. On the one hand, it can prevent a large amount of air from entering. However, many coffee fans who do not know it will squeeze the ventilation valve to test the taste, but in fact, when squeezing out the aroma, the life of the coffee is shortened. Therefore, even if a ventilation valve is installed on the ear-hanging bag, it is not only costly, but also cannot extend its best tasting period.
How to choose hanging ear coffee?
So how to choose ear-hanging coffee? As mentioned in the article on Front Street, hanging coffee is actually fine coffee ground into powder. Therefore, coffee fans can choose the single-origin coffee they usually like. For example, Front Street Panama Butterfly Coffee Beans or Honduras Sherry Coffee Beans, etc. Front Street can help make hanging coffee for coffee fans to choose. Therefore, if you are a friend who also wants to drink coffee during work, you may want to try hanging coffee!
The above is the relevant information about ear-mounted coffee compiled by Front Street. I hope it can help coffee fans who want to know about ear-mounted coffee.
