What Are Drip Coffee Bags? How to Brew the Perfect Drip Coffee? How to Drink Drip Coffee?

Understanding Filter Coffee Bags

In recent years you have probably come across the terms "filter coffee bags" and "drip coffee bags." These are modern products born from two demands at once — good coffee and genuine convenience.

Still, a convenient filter bag is not simply a matter of tearing the packet open and dumping in hot water to get a rich, aromatic cup. A little technique is still required.

Essential Brewing Questions

1. How much water does one filter coffee bag need?

Commercial filter coffee bags usually hold 8-12g of grounds. For a stronger brew, use about 150c.c. of water; for a general brew, the recommended amount is 180-200c.c., adjusted to taste. (FrontStreet Coffee's drip coffee bags contain 10g each and are mostly medium roast, for which we recommend 180c.c. of water.)

2. Do brewing temperature and speed affect flavor?

If you work in an office without a pour-over kettle, dispense from the water cooler with a light touch so the flow stays slow and narrow. First pour in about 30-50c.c. of hot water, wait patiently for 20-30 seconds of soaking, then continue pouring into the cup to a total of 150-200c.c.

If you do have a pour-over kettle and can control temperature, 86-90°C is ideal. A gooseneck spout delivers a more even flow and speed, which ensures the most complete extraction during the brew.

An Important Note

Filter coffee bags are not tea leaves — never try to reuse them for a second infusion. Once extracted, the grounds hold on to bitterness and astringency only, and the flow slows to a crawl. The resulting coffee is unpleasant to drink.

FrontStreet Coffee's Recommended Method

Set out your cup, making sure it is not so shallow that the filter sits in liquid at the bottom. Leave enough room for the coffee to drip from the bag into the cup.

Brew at 88°C. Take the drip coffee bag out of its wrapper, hold the top edge and shake the grounds down below the fold line, then tear along the fold line at the top of the bag.

Open the ear flaps on both sides of the filter and hang them securely on the rim of the cup. First pour just enough hot water to soak the grounds and let them bloom for about 20-25 seconds. Continue pouring in a thin, steady stream, moving in small circles to wet the surface evenly so every particle is fully extracted. The coffee-to-water ratio should be 1:15.

After two minutes, lift the ear flaps off both sides of the cup and enjoy.

FrontStreet Coffee Recommendation

FrontStreet Yirgacheffe Gudingding Cooperative — An excellent bean for drip bags and pour-over alike. This washed Ethiopian lot is processed by the Gudingding team in the Woka area at the southeastern edge of Yirgacheffe, and its clean, precise profile shows jasmine blossom and bright citrus acidity. A medium-light roast brings out green tea and honey notes. It suits pour-over, cold brew, and espresso as well.

FrontStreet Ethiopia Huakui — One of the most successful specialty coffees of recent years. Its defining trait is an explosion of tropical fruit aroma — strawberry, passion fruit, jackfruit, even lychee. Sweetness is obvious, bitterness is very low, and the texture is smooth and juicy, which is why many drinkers call it "the coffee that tastes least like coffee."

FrontStreet Brazil Queen Estate — For those who prefer a gentler cup, this Brazilian single origin is low in acidity and very balanced, with pronounced nut and cocoa aromas and clear caramel sweetness. It goes down smooth without astringency, warm and long in the finish, and works beautifully as a drip bag, pour-over, or moka pot brew.
