Summary of hand flushing skills of Chemex and KONE Fine Coffee

Able Brewing's KONE stainless steel metal filter will transform your Chemex into a coffee maker that can provide stable quality. This article will explain the reasons one by one.

In 2010, the author spent a lot of time learning the so-called technique of making coffee. Some I like very much, others scare me, until I use KONE with the Chemex coffee maker at hand, which is really admiring. The combination of KONE and Chemex coffee maker allows people to enjoy the smooth taste of the filter pot and the hand-brewing method to retain multi-level flavor of good coffee.

Using a Chemex coffee maker to brew coffee is varied for some people. Because of the wide neck design of the Chemex coffee pot, it needs to be extracted with thicker and higher-density filter paper, which relatively makes the flavor of the filter paper possible to blend into the coffee and thus filter out the rich flavor oil. Moreover, the relative increase in the area of filter paper also makes it difficult to grasp the contact time and temperature between hot water and coffee powder. Although good use of Chemex coffee maker and special filter paper can definitely make good coffee, to some extent, it is difficult to achieve a stable consistency in each cup. To be honest, if you want to extract by hand, Hario's V60 filter cup or other plastic filter cup should be more stable than the Chemex coffee maker.

Designed by Keith Gehrke of Portland Coava Coffee, KONE is a reusable stainless steel tapered filter for Chemex coffee pots with a capacity of more than six people. Through the tiny holes in the filter, KONE can completely extract the oil and particles from the coffee. As mentioned earlier, a good cup of coffee can have both the smooth taste of the filter pot and the hand-brewing method to retain multi-layered flavor.

When using KONE correctly, you need to fix some of the hand flushing techniques that used to be taken for granted.

First of all, the coffee powder should be ground much finer than using filter paper, and then, do not stir the coffee powder as much as possible when injecting water. If you use the KONE filter in the traditional way, such as rough grinding and stirring the coffee powder, the water will stay on the filter for too short, thus extracting the coffee with insufficient flavor. The magic of KONE is that it uses finely ground coffee to extend the extraction time and enables coffee to be extracted evenly through holes in the entire filter. In order to give full play to the design of the KONE, it is necessary to use a hand punch to provide a stable flow and hold the water injection position. Of course, a good bean grinder is also very important. As for the amount of powder, Able Brewing recommends 25 grams of fine to moderately ground coffee powder versus 400 grams of water. After several times of water injection, wait for one minute after the first water injection, so that the coffee powder is fully infiltrated, then add the remaining water, and inject water slowly. The whole extraction time usually takes two to three minutes.
