How Long is the Shelf Life of Drip Coffee Bags? How to Brew Drip Coffee? Can it be Brewed Multiple Times?

The Growing Coffee Culture and FrontStreet Coffee's Journey

Nowadays, more and more people are falling in love with coffee and exploring coffee culture. FrontStreet Coffee has been in business for 12 years, witnessing the continuous evolution of coffee trends—from instant 3-in-1 coffee to capsule coffee, and now to pour-over coffee as the mainstream with drip bag coffee as a supplement. FrontStreet Coffee continues to innovate and develop, keeping pace with the times by launching drip bag coffee, which everyone can purchase through Taobao and Tmall.

The Origins and Market Demand for Drip Bag Coffee

Of course, drip bag coffee was not originally created by FrontStreet Coffee. The history of drip bag coffee traces back to Japan's UCC Ueshima Coffee, and this brewing method is extremely convenient and efficient. When people don't have extra time to visit a coffee shop for a meticulously crafted pour-over coffee made by a barista, drip bag coffee gained popularity among many coffee enthusiasts as soon as it entered the market. Among customers who come to FrontStreet Coffee for coffee, many ask if the shop sells drip bag coffee, which demonstrates how widespread the market for drip bag coffee has become.

The emergence of drip bag coffee largely stems from customer demand. As FrontStreet Coffee discovered through conversations with customers, many people cannot afford to buy an espresso machine, grinder, dripper, and other equipment just for drinking coffee—except for the extremely passionate coffee enthusiasts. Even if you have a complete set of coffee equipment, many people actually don't have time to make coffee. This is how drip bag coffee came into everyone's view.

Understanding the Optimal Flavor Period of Coffee

Just like agricultural products, drip bag coffee follows the principle of freshness. While agricultural products emphasize freshness, coffee focuses on optimal flavor, also known as the best tasting period. Therefore, FrontStreet Coffee generally recommends consuming coffee during its optimal flavor period, as the taste of drip bag coffee will gradually change over time. You might ask, what exactly is the optimal flavor period for coffee?

Generally speaking, the optimal flavor period for coffee drip bags refers to the time from two days after roasting the beans until the appearance of distinct flavors, commonly called the coffee's optimal flavor period. Typically, light roast coffee drip bags have an optimal flavor period of about 2-3 weeks; medium roast drip bags about 2 weeks; and dark roast within 2 weeks. Therefore, to experience the best flavor of coffee, FrontStreet Coffee recommends finishing the coffee within two weeks.

How to Brew Drip Bag Coffee Correctly

Actually, don't overthink making drip bag coffee—you just need hot water at a suitable temperature and a cup with a capacity of about 150-180 milliliters to brew a cup of authentic black coffee. Since drip bag coffee has standard capacity, like FrontStreet Coffee sets the capacity at 10 grams per small bag, with each bag brewing 150 milliliters of black coffee. FrontStreet Coffee also advises against purchasing too many drip bags at once, because as mentioned earlier, once the coffee passes its optimal flavor period, its best flavor will be gone. Of course, many customers store leftover coffee in the refrigerator, but FrontStreet Coffee strongly recommends against storing drip bag coffee in the refrigerator, because the coffee powder inside has absorbent properties, and putting it in the refrigerator will cause the coffee powder to lose flavor, so try to avoid this practice.

FrontStreet Coffee considers drip bag coffee as a simplified pour-over method, where brewing time, temperature, and water amount have certain requirements. The water temperature for drip bag coffee is quite particular and is determined by the flavor characteristics of different origins and roast levels. For darker roasts, FrontStreet Coffee's drip bags work best with 88°C water, while light roasts are best with 90-92°C water. However, friends don't need to worry about identifying coffee roast levels—FrontStreet Coffee's official WeChat account has published relevant knowledge about drip bag coffee and brewing methods, so feel free to purchase with confidence.

Many customers often visit FrontStreet Coffee's shop to ask whether drip bag coffee can be brewed multiple times. Actually, one small bag of drip coffee typically contains 10 grams of coffee grounds, which can generally only be brewed once. When you try to brew it multiple times, you might notice the coffee still tastes strong and should still be drinkable. However, this is not the case. When you brew drip bag coffee for an extended time, the longer the coffee steeps, the more caffeine is released. This is because the coffee has been over-extracted, and over-extraction will release bitterness and astringency from the coffee, meaning the optimal flavor of this coffee is essentially gone. Even if the coffee is within its optimal flavor period, multiple brewings will diminish the coffee's best flavor, so FrontStreet Coffee generally does not recommend customers brewing the same drip bag coffee multiple times.

If you purchase drip bag coffee to brew at home but fail to extract the optimal flavor, that bag of drip coffee is wasted. Therefore, everyone must brew during the coffee's optimal flavor period. To extract the best flavor from drip bag coffee, you need to pay attention to brewing parameters. Although the process of brewing drip bag coffee is similar to pour-over, FrontStreet Coffee recommends against directly copying pour-over methods. Because the design of drip bags is not as conducive to heat retention as V60 drippers, the actual temperature will be lower, so FrontStreet Coffee recommends increasing the water temperature by 1 degree during brewing, which helps extract the coffee's optimal flavor better.

If you visit FrontStreet Coffee's shop, you'll notice that our baristas typically use 15 grams of coffee grounds to brew 225 milliliters of coffee when making pour-over for customers, and never reuse leftover coffee grounds for subsequent brews, because FrontStreet Coffee wants to serve every customer a cup of coffee with optimal flavor—this is FrontStreet Coffee's original mission.

How to Identify Fresh Drip Bag Coffee

Additionally, FrontStreet Coffee would like to share a small tip on how to determine whether the drip bag coffee you purchase is fresh. First, when buying drip bag coffee, check the roast date on the packaging. The roast date indicates when the coffee beans were roasted, and when we talk about coffee freshness, we generally look at the roast date rather than the expiration date. Because freshly roasted coffee undergoes a self-fermentation process within a week that helps the flavor reach perfection, after this stage, the coffee begins to oxidize and volatilize, and its characteristic aroma becomes less pronounced.

Generally, if a coffee package doesn't indicate a date, it might be drip bag coffee that has been sitting for a long time. Although the shelf life is typically much longer than the optimal flavor period, passing the optimal flavor period doesn't mean it's undrinkable. FrontStreet Coffee believes that when coffee passes its optimal flavor period, the brewed coffee's flavor and texture won't be as good. Because when you brew coffee during its optimal flavor period, the brewed coffee will have very rich oils, with the characteristic sweetness of coffee, and the coffee aroma it releases is truly refreshing.

Then, when you brew drip bag coffee, if the coffee is fresh and within its optimal flavor period, you'll notice a bulging phenomenon in the center of the coffee grounds when adding hot water—the fresher the coffee, the more obvious this phenomenon. This is generally called "bloom brewing." Generally, light roast beans don't expand as obviously as dark roast beans.

Also, FrontStreet Coffee recommends that when purchasing drip bag coffee, try not to buy coffee that was ground more than five days ago, because once coffee beans are ground into powder, the coffee quickly loses its characteristic aroma, significantly reducing its flavor. Just like customers who buy coffee beans from FrontStreet Coffee, we recommend that customers grind beans just before drinking. However, many customers don't have grinders at home and have their beans ground at FrontStreet Coffee's shop, but FrontStreet Coffee still recommends trying to finish the coffee within its optimal flavor period.

Choosing the Right Drip Bag Coffee for Your Taste

Once you've decided to purchase drip bag coffee, the question that troubles you is how to choose the right drip bag coffee brand for yourself. FrontStreet Coffee recommends buying seasonal drip bags from specific origins. For example, FrontStreet Coffee's seasonal drip bags mainly feature coffee from seven origins that best represent each region's flavor characteristics, similar to FrontStreet Coffee's daily beans.

For instance, if you like coffee with citrus and fruit notes, FrontStreet Coffee would recommend purchasing Ethiopian Yirgacheffe drip bag coffee; if you prefer sweeter coffee flavors, like sweet orange and honey, you could try FrontStreet Coffee's Guatemala Huehuetenango drip bag coffee; if you like the rich nutty and chocolate flavors of American coffees, then FrontStreet Coffee's Brazil Cerrado, Colombia Huilan, and Costa Rica Tarrazú drip bags would be perfect for you.

If your taste is more intense, you can boldly try FrontStreet Coffee's Indonesian Mandheling drip bag coffee—the wild herbal and medicinal notes will be truly unforgettable! If you can't accept Mandheling's unique flavor profile, why not try FrontStreet Coffee's Yunnan small bean drip bag coffee, with its light fruity tea-like notes, somewhat similar to the feeling of drinking tea. If you have difficulty choosing, take some time to visit FrontStreet Coffee's shop and let our baristas help you select a drip bag coffee brand that suits you.

Drip Bag Coffee Brewing Guide

Additionally, FrontStreet Coffee would like to share the brewing method for drip bag coffee.

The Drip Bag Coffee Brewing Process

1. Warm the Cup

Prepare your cup and first pour in some hot water to warm it. The purpose is to prevent the brewed coffee from cooling down too quickly, as the coffee's flavor continuously changes with temperature drops. If it cools too quickly, you'll miss many different taste sensations.

2. Water Temperature

The brewing water temperature is very important, with a recommended temperature between 85-90°C. If the brewed coffee is too bitter, try lowering the water temperature. Conversely, if it's too weak or too astringent, you can increase the water temperature, but still within the 85-90°C range.

3. Prepare the Drip Bag

First, gently shake the drip bag to settle the coffee grounds and avoid scattering when opening. Then pour out the hot water from the cup. After tearing open the seal on the drip bag, open the paper hangers on both sides, shake to level the coffee grounds, and finally hang it on the cup rim.

4. Pre-wet

The amount of water for the first pour should be just enough to wet the coffee grounds—too much or too little will affect the flavor. Then wait 20 seconds for the coffee grounds to fully absorb the water. The coffee's strength can be adjusted by the pre-wetting time—extending it to 40 seconds will yield stronger coffee.

5. Pour Water

For the second pour, you can fill to eight-tenths of the filter paper's capacity. It's best to use a thin, steady stream of water. After the water level drops to the pre-wet height, you can continue pouring to eight-tenths full until you've extracted 150-180cc. Once extraction is complete, you don't need to wait for all the water in the filter paper to drip out—just discard it directly.

6. Enjoy Your Coffee!

Remember that you can taste different flavors as the temperature changes!
