Drip method is also called Japanese drip method.

For coffee powder, water droplets are the best amount of water to absorb, because when the water droplets continue to drop on the powder layer, they do not spread immediately, and because the amount of water droplets is small, it is easier for coffee powder particles to absorb water, so for tapered filter cups with deeper powder layers, water droplet boiling is an excellent way to feed water.

The purpose of drip steaming is to allow hot water to come up slowly from the bottom, to ensure that the coffee powder in the filter cup can be evenly soaked in hot water to achieve effective and complete steaming, this method takes a long time, and also requires appropriate hand flushing pots and skills. The latter stage of heavy water injection requires more practice to avoid smelly, which is a more difficult way of hand flushing.

Recommended apparatus

Kono filter cup

Looking at the ribs of the filter cup, it is found that the ribs of the KONO do not extend from the bottom to the top, but stop when they are less than half the height of the filter cup. This height is designed to ensure that during the dripping process, the filter paper can be attached to the wall of the filter cup after absorbing water, and once the exhaust space is limited, the air flow will be limited, which will increase the water absorption time of coffee powder particles.

Therefore, when using the KONO filter cup, when using the drop method to produce a small water column, in order to maintain the pneumatic extraction, it is necessary to feed the water until the water level reaches a little more water above the ribs, so that the filter paper can be closely attached to the wall of the filter cup, preventing the air from flowing upward, creating a relatively airtight space, because the upward passage is blocked, and the water can only flow in the direction of the filter paper and the ribs. The internal water will continue to be pushed down until the pneumatic extraction water column is produced and continues until the water flows out, so the key to using the KONO filter cup is to keep the feed water above the ribs in order to produce the pneumatic extraction of KONO.

Kalita elephant trunk kettle

Very round goose mouth design, after practice, you can easily use Japanese drip method to inject water, suitable for deep-roasted coffee beans.

The neck of the kettle does not rise smoothly, but shows a triangular streamline, gradually converging from the kettle body to the tip of the mouth, increasing the Radian, so as to limit the flow rate of the water and make the strength of the water softer.

The brass material conducts heat quickly, and the handle is made of resin, which is effective in heat insulation and not hot.

The range of water injection is widely used, and different degrees of water output can be applied when brewing coffee powder of different sizes.

The purpose of drip steaming is to allow hot water to come up slowly from the bottom, to ensure that the coffee powder in the filter cup can be evenly soaked in hot water to achieve effective and complete steaming, this method takes a long time, and also requires appropriate hand flushing pots and skills. The latter stage of heavy water injection requires more practice to avoid smelly, which is a more difficult way of hand flushing.

Improper control is easy to produce the phenomenon of unstable flow thickness, and the users have higher requirements for brewing skills.
