The Origin of Drip Coffee Bags: How Were Drip Coffee Bags Invented? Are Drip Coffee Bags Good?

Many people find brewing a cup of coffee too much of a chore, which makes it hard to enjoy good black coffee whenever they want. Drip bag coffee changed all that. Today FrontStreet Coffee walks you through how to make a genuinely enjoyable cup with almost no effort at all.

The Invention of Drip Bag Coffee

In China, finding drip bag coffee — also called hanging filter coffee — is no trouble at all: it is sold on the major e-commerce platforms, in supermarkets, and in most coffee shops. Brewing your own has become completely ordinary. But do you know which country invented it? Not the mature coffee markets of Europe and America, but Japan, China's neighbor.

Mention Japanese coffee and most people picture pour-over, which is indeed hugely popular there. But young Japanese office workers with fast-paced lives do not have time to wait for a hand-poured cup.

With a drip bag, all you need is hot water and a suitably sized mug to enjoy good coffee anytime, anywhere.

So in 1990, Japan's Yamanaka Industry Co., Ltd. applied the tea-bag concept to coffee, invented drip bag coffee, and filed a patent. Their design, however, could not support the weight of brewing coffee and easily tipped over mid-brew, so it never reached the market successfully. It was not until 1998 that Taiki Shoji improved the idea by extending the hanging parts outward, giving us the modern drip bag we know today.

The Drip Bag Coffee Market

The English term for drip bag coffee is "instant drip coffee bag." It carries the advantages of instant coffee — quick, convenient, no equipment needed — while still letting people enjoy the pleasure of pour-over. Because it combines the best of both, it has grown quickly across East Asia. In 2011, global sales reached 1.4 billion bags, roughly 11,200 metric tons, with 94% of sales coming from Japan. Starbucks Japan even launched a dedicated drip bag line for that market. Today's global volume is still modest and the market small, but the growth rate is remarkable.

In China's brewed coffee market, instant coffee once held as much as 70% share, while drip bag coffee managed only 10%. In recent years, though, food-safety scandals have left consumers uneasy, and specialty coffee culture has taken off, so coffee drinkers no longer care only about staying awake. Drip bag coffee, combining quality and convenience, answers exactly that need. As a result, China's drip bag growth rate hit 30% in 2017.

Drip Bag Coffee vs. Freshly Ground Coffee

As drip bag packaging technology has advanced, the bags can now fully block outside oxygen. So as long as the coffee inside is good quality and drunk within its optimal window, there is essentially no meaningful difference between a drip bag and freshly ground pour-over.

The biggest advantage of brewing a drip bag is that professional baristas have already fixed most of the variables for you. You do not need to choose beans, weigh out a ratio, dial in a grind size, or own brewing equipment and expert-level technique. All you need is hot water and a suitably sized mug to enjoy good coffee anytime, anywhere.

How to Brew Drip Bag Coffee

1. First, the coffee content is clearly marked on the bag (usually 10 grams). That solves the problems of needing a grinder and a scale.

2. Next, water amount and temperature. Just as with pour-over, use a 1:15–1:16 ratio, so the finished coffee reaches 140–150 milliliters. Use water around 90°C. A thermometer or temperature-controlled kettle is ideal. If you have neither, you can estimate: after boiling water in a kettle, turn off the heat, open the lid, and wait 2–3 minutes for it to reach roughly 90°C (at a room temperature of 28°C).

3. Once you are ready, take out the drip bag, open the sealed top, unfold the "ears" on both sides of the filter, hang it on the rim of a mug (or cup), and shake the grounds flat.

4. For the first pour, simply wet all the grounds and let them bloom for 30 seconds.

5. After the bloom, add water again. Use a small stream in circular motions to fill directly, wait for the coffee bed to drop slightly, then keep adding water until full. Repeat until the coffee in the cup reaches about 140–150 milliliters, then remove the bag and enjoy.

6. For more precise water amount, pour 150–160 milliliters into your pouring kettle. During brewing, once all the water has been poured and the coffee has flowed into the cup, you can remove the bag. The whole process takes about 1 minute.

Because drip bag coffee uses pre-ground coffee, its flavor fades faster than whole beans. To enjoy it at its best, drink it as soon as possible.

Drip Bag Coffee Brand Recommendations

FrontStreet Coffee's freshly roasted seasonal drip bag coffee gives you strong guarantees on both brand and quality. More importantly, the value is exceptional — a box of ten bags, each holding 10 grams, costs just 39.9 yuan. At one bag per cup, with each bag making 150 ml, that works out to roughly 4 yuan a cup. Set that against coffee shops charging dozens of yuan per cup, and it is a genuinely honest recommendation.

FrontStreet Coffee Indonesia PWN Golden Mandheling Drip Bag Coffee Beans

Mandheling has drawn plenty of attention in recent years. FrontStreet Coffee's earlier Mandheling sales were mostly in the Shanghai area, and Shanghai and Taiwan share quite similar taste preferences — both favor rich, full-bodied flavor. One Shanghai customer kept insisting that Mandheling should be roasted darker than our usual dark roast. Today, more and more people appreciate Mandheling's distinctive character, and an increasing share of the customers ordering it from FrontStreet Coffee come from the Guangzhou neighborhood.

FrontStreet Coffee's Indonesia PWN Golden Mandheling is genuinely different from ordinary Mandheling. It comes from the Indonesian green-bean supplier PWN, the first company to work with Japan on Golden Mandheling and to register the name as a trademark. Its defining trait is that it lacks the off-taste common in regular Mandheling. Three rounds of strict hand-sorting ensure uniformly sized beans, which in turn give even color during roasting. The result is a clean, full-bodied cup, much like Guangdong's herbal tea — so it is no wonder Guangzhou drinkers take to it. FrontStreet Coffee created Golden Mandheling drip bags precisely because acceptance of this flavor keeps rising.

FrontStreet Coffee Recommendation

Drip bags make the most sense with beans that stay delicious even when brewed simply, and two FrontStreet Coffee staples fit that brief perfectly. The PWN Indonesia Golden Mandheling is roasted dark, with very low acidity and a thick, long-lasting body. The cup is full of herbal and dark chocolate aroma, layered with a faint earthy note — ideal for drinkers who like bold flavor and no sourness. If Mandheling and Blue Mountain are still the go-to picks for anyone who loves a rich cup, this is why.

If you prefer balance over boldness, the Jamaica Blue Mountain No.1 is the other natural fit. It avoids the sharp fruit acidity of some African coffees and the heavy bitterness of a dark roast, striking a rare equilibrium among acidity, sweetness, bitterness, and aroma. Expect a complex blend of cream, caramel, chocolate, nuts, honey, and light fruit, with a soft, rounded entry, generous mid-palate sweetness, and a clean, lingering finish. That near-perfect balance is exactly why so many coffee professionals call it the easiest specialty coffee for almost anyone to love.

For a lighter, brighter option that still shines as a drip bag, FrontStreet Coffee also offers a washed Yirgacheffe, whose jasmine florals, citrus acidity, and tea-like finish make a clean, refreshing cup with no bitterness at all.
