How to Use a Drip Coffee Maker With a KONO Dripper

A KONO cone dripper uses short ribs that limit airflow and slow the flow rate, which extends contact time between water and coffee. The result is a more balanced extraction with fuller body than a fast-draining cone, and the effect is strongest with medium-dark roasts that need gentler, longer steeping.

The KONO brand, founded in 1925, made an early siphon coffee maker and launched Japan's first cone-shaped dripper in 1973. For brewing, use a medium-fine grind, water around 88 to 92 degrees Celsius, a ratio near 1:15, and a three-stage pour. Rinse the paper filter first.

As a well-known Japanese coffee equipment brand, KONO's cone-shaped dripper occupies an important position in the drip coffee world thanks to its unique short-rib design. This article starts from the historical origins of the KONO dripper and takes a deep look at how its rib structure slows the flow rate by limiting exhaust space and extends the steeping time, thereby improving extraction balance and body. At the same time, in response to the brewing needs of medium-dark roasted coffee beans, it shares the practical parameters used in Front Street Coffee stores, including grind size, water temperature, coffee-to-water ratio, and a three-stage pouring plan, and recommends several classic beans that pair well with this dripper, helping coffee lovers fully master the logic of using the KONO dripper.

Kōno (コーノ), a equipment brand that is a household name in the Japanese coffee world.

Founded in 1925, KONO (Coffee Syphon Company) created the world's first siphon coffee maker, and then in 1973 launched Japan's first cone-shaped dripper, allowing paper filters to also present a flavor performance similar to that of flannel cloth.

After that, the brand successively developed different models of drippers for professional coffee practitioners and pour-over beginners, and won high praise in the Japanese and even global coffee circles. Next, follow Front Street Coffee (FrontStreet Coffee) to explore the unique features of the KONO dripper～

What is the Kono dripper?

Kono is a well-known company in Japan's coffee equipment manufacturing field. The founder was named Toshio Kono, and the dripper products are named after his surname.

Kono's coffee drippers and original wooden-handle coffee pots have always enjoyed an extremely high reputation among drip coffee fans. Mr. Kono, the president responsible for designing coffee drippers and coffee pots, has devoted himself to the study of delicious coffee for many years, creating a series of Kono-style drippers with a pastoral feel and original wooden-handle coffee pots.

Kono is the professional equipment most commonly chosen by major Japanese coffee specialty stores and professionals, and is also the product favored by many drip coffee enthusiasts.

Features of the Kono dripper

What makes the Kono dripper unique is that its "rib" guide grooves extend all the way to the bottom of the hole where the coffee liquid flows out. Because the ribs are located at the bottom and are very short, they fit closely with the filter paper, so the flow rate is slower than that of the V60. The ribs create tiny gaps between the cone wall and the filter paper, allowing coffee liquid to seep out from the filter paper, while the part clinging tightly to the wall will not let coffee liquid pass through.

A closer look at the rib structure of the KONO dripper reveals that the Kono has a total of 12 ribs, whose height is far lower than that of the Hario V60, ending at a position less than half the height of the dripper.

If the ribs are too short or too shallow, the range from which coffee liquid can seep out becomes too narrow, and the extraction time will be prolonged; conversely, if the ribs are too long, the contact time between hot water and coffee grounds is too brief, the liquid flows out quickly, and impurities floating on the surface are also likely to mix into the coffee.

The design of the ribs makes the dripper fit tightly with the filter paper, ensuring that the exhaust space is limited during the drip process, air flow is naturally obstructed, and the flow rate slows accordingly.

As a result, the coffee grounds remain in a steeped state for most of the time, the water absorption time of the coffee particles is increased, and the coffee finally extracted is overall more balanced, making under-extraction less likely.

What kind of coffee is the KONO dripper suitable for brewing?

The short-rib design prolongs the coffee extraction time, thereby achieving the effect of increasing the extraction yield and the body of the coffee, so it is suitable for coffee beans that need to show a rich mouthfeel. When Front Street Coffee (FrontStreet Coffee) brews medium-dark roasted coffee beans in its daily store operations, it chooses the KONO dripper.

For example, "Front Street Coffee (FrontStreet Coffee) - Jamaica Blue Mountain No. 1 Coffee Beans," "Front Street Coffee (FrontStreet Coffee) - Papua New Guinea Paradise Bird Coffee Beans," "Front Street Coffee (FrontStreet Coffee) - Brazil Queen's Estate Coffee Beans," and "Front Street Coffee (FrontStreet Coffee) - Front Street PWN Golden Mandheling Coffee Beans" are all brewed and served using the KONO dripper～

How to use the KONO dripper to brew coffee?

The longer coffee beans are roasted, the greater the changes in their internal structure, and the looser their texture becomes. This means the coffee substances release flavor components more easily in hot water. In addition, the KONO dripper itself has the effect of improving the extraction yield, so when using the KONO dripper to brew medium-dark roasted coffee beans, it is recommended to use medium-coarse coffee particles (65-70% passing rate through China standard No. 20 sieve).

During brewing, it is also not recommended to use too high a water temperature. When Front Street Coffee (FrontStreet Coffee) stores produce medium-dark roasted coffee, they use water at 88-89 degrees Celsius, with a 1:15 coffee-to-water ratio and three-stage pouring～

The brewing process is divided into three stages of pouring. In the first stage, pour 30 grams for blooming, with a blooming time of 30 seconds. In the second stage, pour up to 125 grams, with a 10-second interval in between, then pour the remaining water, that is, up to 225 grams. The total extraction time is about 2 minutes.
