Black coffee is often said to help with weight loss and is good for health, but what exactly is black coffee? To put it plainly, black coffee is actually a coffee without any modifications, bringing the pure experience of savoring coffee.

Drip bag coffee is becoming increasingly popular in the market, with more and more people discovering the flavor enjoyment that single-origin coffee brings. From instant coffee that simply requires adding hot water and stirring to drip bag coffee that hangs on the cup and is brewed with hot water, it's quick while still allowing you to enjoy the process. When you're tired from work, brewing a cup of drip bag coffee can provide comfort to both your mind and taste buds. In addition to the 10 types of FrontStreet Coffee drip bag coffee available online, FrontStreet Coffee also allows customers to choose their desired coffee beans, which are then processed into drip bag coffee to meet every customer's needs. With all that said, how should drip bag coffee be brewed?

The Origin of Drip Bag Coffee

In 1990, Japan's Yamanaka Industries was inspired by string tea bags and invented filter-style coffee, applying for a patent. However, the initial version couldn't support the weight of brewing coffee and easily lost balance during the brewing process, leading to uneven extraction, so it wasn't successfully commercialized. In 2001, Japan's UCC Ueshima Coffee extended the hanging part outward and registered a patent, creating the drip bag coffee we know today, which was then launched into the market. Every convenient product that appears goes through countless failures and experiments to achieve the best results. The emergence of drip bag coffee was to allow people to conveniently enjoy high-quality single-origin coffee, rather than settling for low-quality and unhealthy instant coffee powder.

The Principle of Drip Bag Coffee

The principle of drip bag coffee involves placing pre-ground coffee powder in a non-woven fabric bag and extracting flavors by pouring hot water through the coffee powder layer. Compared to pour-over coffee, drip bag coffee doesn't require preparing a filter cup, filter paper, or grinder, reducing operational complexity and making the brewing technique less demanding.

Why Can't Drip Bag Coffee Be Soaked?

The coffee powder in drip bags is ground finer than that used for pour-over coffee, which means that during brewing, the coffee flavors release into water more quickly. When drip bag coffee brewing is complete, 30% of the flavor compounds from the coffee beans are released, while the remaining 70% consists of the coffee beans' woody fiber. If the drip bag isn't removed promptly after brewing, the woody fiber flavors will release into the extracted coffee, causing bitterness and woody tastes in the coffee. Therefore, remember to remove the coffee bag promptly after brewing and don't perform a second brew. FrontStreet Coffee's drip bags offer great value for money, so you don't need to feel wasteful - this is the "mission" of coffee beans.

How to Brew Drip Bag Coffee?

To brew FrontStreet Coffee drip bags, we only need three things: drip bag coffee, a cup, and hot water.

You read that right - it's that convenient. At this point, some might ask: "Don't you need an electronic scale? Don't you need a thermometer? Don't you need a gooseneck kettle?" You really don't! Of course, having these tools would be ideal. The coffee powder in drip bag coffee bags is ground finer than that used for pour-over coffee. When coffee particles become smaller, flavor release happens faster, so you can brew a delicious cup of single-origin coffee without being too particular about technique.

First, tear open the outer packaging of the FrontStreet Coffee drip bag and take out the coffee filter bag inside. Then tear along the dotted line marked "OPEN" printed on the coffee filter bag, unfold the drip bag coffee, and extend the two paper "ears" to hang on the cup or kettle mouth.

FrontStreet Coffee's drip bag coffee contains 10g of coffee powder. FrontStreet Coffee recommends a brewing ratio of 1:15, as this ratio produces the most balanced and stable coffee flavor.

First, pour a small amount of hot water to ensure all coffee powder is moistened, with a bloom time of 10-20 seconds to allow carbon dioxide in the coffee powder to escape, ensuring stable subsequent extraction. For the second pour, add water until nearly reaching the edge of the filter bag, then stop. After the coffee liquid drops by half, pour water again to nearly the filter bag edge. With a total of three pours, wait for all remaining coffee liquid to pass through the coffee powder and drip into the cup, then remove the drip bag to enjoy.
