Coffee Is a Type of Drip Bag Product With a Shorter Shelf Life

Why Does Coffee Is a Type of Product Matter for Storage?

Drip bag coffee is a type of product made by grinding freshly roasted beans and sealing the grounds in a filter bag for brewing at any time. Its flavor window is much shorter than that of whole beans: roasted beans keep well for about two months, while drip bags often taste good within about two weeks, or at most one month.

The reason is surface area. Grinding exposes far more of the coffee to oxygen, so aroma compounds escape several times faster than from intact beans. Because drip bags are made from ground coffee, they lose the gases and volatile aromatics that carry sweetness, fruit and floral notes, which is why storage time limits differ so sharply.

Drip bag coffee, with its convenience of being ready to drink immediately upon opening, has become a daily choice for many office worker coffee enthusiasts. However, it differs noticeably from coffee beans in terms of shelf life: coffee beans lose their aroma continuously after roasting, and Front Street typically recommends that customers finish them within two months; while drip bags made from ground coffee lose their aroma at an accelerated rate, with optimal flavor often lasting only about two weeks. This article will explain the origins of drip bag coffee, the correct brewing steps, common misconceptions, and the reasons for the shortened flavor window, while also introducing Front Street's drip bag products developed for coffee enthusiasts, such as Honduras Lychee Orchid and Sherry, to help everyone recreate as much as possible the aroma and layers that a cup of specialty coffee should have in actual drinking.

Drip bag coffee is a type of coffee product made by grinding freshly roasted coffee beans into powder, putting them into a filter bag, and allowing them to be opened and brewed at any time. Compared with instant coffee that contains additives, its "freshness period" is actually shorter. As is well known, after coffee beans complete roasting, their aroma continuously dissipates with the release of gases, and Front Street generally recommends that customers drink them within two months; after being ground into powder and made into drip bags, the rate of aroma loss increases several times over. Therefore, if you want to drink coffee in its best condition, it is best to finish it within one month.

What is drip bag coffee?

The emergence of drip bag coffee is related to economic development and the acceleration of life's pace. Many coffee enthusiasts who have already entered the workplace do not have ample time to make pour-over coffee. If operated hastily, the brewed coffee is mostly not tasty, and drip bag coffee was thus born.

According to Front Street's understanding, it was initially Yamanaka Sangyo Co., Ltd. of Japan that applied the concept of tea bags to coffee, invented filter-drip coffee, and applied for a patent. However, the drip bag designed by Yamanaka Sangyo could not withstand the weight when brewing coffee and was also prone to losing balance during brewing, so it was not successfully commercialized. It was not until 1998 that Daiki Shoji improved the original invention by extending the hanging ear portions outward, forming the drip bag coffee we are familiar with today.

Most coffee enthusiast friends who come to Front Street stores to buy drip bag coffee are also office workers. Driven by everyone's support and demand, Front Street began developing some single-origin coffee beans suitable for making into drip bag coffee, for Front Street's coffee enthusiasts to taste. For example, the Honduras Lychee Orchid coffee beans and Sherry coffee beans most loved recently by Front Street Coffee enthusiasts have been made by Front Street into drip bag coffee. However, some coffee enthusiasts new to drip bag coffee are confused about how to brew it correctly, so next Front Street will demonstrate the correct brewing method.

Correct brewing method for drip bag coffee 1 . Warm the cup

First prepare the cup to be used for brewing drip bag coffee, pour in some hot water to warm the cup. This is done so that the brewed coffee does not cool down too quickly. Coffee presents different flavors as the temperature drops, which is the so-called sense of layers. If it cools too quickly, many taste sensations will be missed. 2. Water temperature The brewing water temperature is very critical, and it is recommended to control it between 85 and 90 degrees. If the brewed coffee tastes too bitter, try lowering the water temperature; conversely, if it is too light or too astringent, raise the water temperature, but it should still remain within the range of 85 to 90 degrees. 3. Hang on the rim

First gently shake the drip bag to let the coffee grounds fall back to the bottom, avoiding powder spilling out when tearing it open. Then pour out the hot water used to warm the cup, tear open the seal strip on the drip bag, spread open the paper hanging ears on both sides, shake to level the coffee grounds, and finally hang it on the rim of the cup. 4. Pre-wet the drip bag coffee

For the first pour, the amount of water should be just enough to moisten the coffee grounds; too much or too little will affect the flavor. Then wait 20 seconds to let the coffee grounds fully absorb water. The strength of the coffee can be adjusted through the pre-wetting time; extending it to 40 seconds can produce stronger coffee. 5. Pouring water

For the second pour, you can fill to eight-tenths of the filter paper, preferably using a thin, slender stream of water. After the water level drops to the height at pre-wetting, continue pouring to eight-tenths full until 150 to 180 cc has been extracted. After extraction is complete, there is no need to wait for all the water in the filter paper to drain; simply discard it directly.

Why brew drip bag coffee correctly

Front Street thinks some coffee enthusiasts may wonder: why can't drip bag coffee be directly soaked like a tea bag? This brings us to specialty coffee. Coffee enthusiasts who have drunk specialty coffee all know that if over-extracted during pour-over, the coffee becomes bitter and unpleasant, which is why the brewing time needs to be streamlined. Drip bag coffee is actually a portable version of specialty coffee. It itself is made by turning ground coffee into a powder bag, only saving coffee enthusiasts the step of grinding it themselves. Therefore, if it is not brewed correctly, the flavor will likewise not be good.

Notes for brewing drip bag coffee: 1. It cannot be brewed repeatedly. 2. After brewing, the coffee grounds cannot continue to soak in the cup, otherwise over-extraction will occur. 3. Directly throwing the drip bag coffee into the cup is very convenient, but before the hot water completely soaks the powder bag, the water temperature has already begun to drop, causing insufficient extraction and affecting the drinking taste and flavor.

Best flavor period for drip bag coffee

As Front Street said above, a drip bag coffee packet is actually pre-ground specialty coffee powder, so the shelf life should be about the same. But in fact, the flavor period of drip bag coffee is somewhat shorter than that of coffee beans. Generally speaking, after coffee beans are made into drip bag coffee, they need to be finished within two weeks. This is because making drip bag coffee first requires grinding the coffee beans into powder, which increases the surface area of the coffee exposed to air, making preservation more difficult. Only within two weeks can the original aroma of the coffee be fully enjoyed. However, this requirement is only for coffee enthusiasts who have demands regarding flavor; if there are no high demands for coffee aroma and flavor, then actually even if finished within one year, the coffee beans will not spoil.

And making the flavor period of drip bag coffee longer is actually very difficult to achieve. According to Front Street's practice, even using vacuum packaging cannot inhibit the disappearance of coffee aroma, because from the moment coffee beans complete roasting, carbon dioxide will be released. Therefore, careful coffee enthusiasts, when receiving drip bag coffee mailed by Front Street, can notice that the packaging is somewhat puffed up. This means that this packet of coffee was packaged while fresh, and when the coffee enthusiast receives it, it is exactly at the best flavor period.

After the carbon dioxide in the coffee is fully released (about two weeks), it begins to release aroma. No change can be seen on the surface, but the coffee has already gradually deteriorated. Left at room temperature for more than two weeks, the coffee's aroma has probably mostly disappeared. But because the drip bag is sealed packaging, the fragrance can still be smelled when opened, only it is not so fragrant after brewing. Therefore, Front Street recommends that coffee enthusiasts finish it within two weeks after receiving the drip bag coffee, so that they can taste its best flavor.

So coffee enthusiasts can see in the coffee market that many coffee bean packages are equipped with one-way valves, the purpose being to allow the coffee's carbon dioxide to be released, so as to prevent the package from bursting due to the expansion of carbon dioxide, while on the other hand also preventing a large amount of air from entering. But many coffee enthusiasts who do not know this squeeze the one-way valve to smell the aroma, yet in fact, while squeezing out the fragrance, they also shorten the life of the coffee. So even if a drip bag packet is equipped with a one-way valve, not only is the cost high, but it also cannot extend its best flavor period.

How to choose drip bag coffee?

So how should one choose drip bag coffee? As Front Street said above, drip bag coffee is actually ground specialty coffee, so coffee enthusiast friends can simply choose according to 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 them into drip bag coffee for coffee enthusiasts to choose from. Therefore, if you are a friend who also really wants to drink coffee during work, you might as well try drip bag coffee!
