Those who are keen on hand-dripping coffee also know that the structural design and dripping speed of the filter cup are also directly related to the performance of coffee flavor and the extraction rate, so put aside the external appearance and strive to study the products with optimized internal structure of the filter cup. in fact, we do not see much on the market at present, in addition to brand differences, the appearance structure is almost the same, there is no essential difference. However, the filter cup to be shared today is a bit special, and in about two weeks, financing has been completed in kickstarter with a high-profile rate of 333%, and will be officially put on the market soon.

This filter cup is called "The December Coffee Dripper". Let's call it "December filter cup" for the time being. The filter cup was officially financed on kickstarter on April 11 this year, sponsored by Nicholas Cho, from the Wrecking Ball Coffee Roasters boutique Cafe in San Francisco, USA.

As we all know, to extract satisfactory coffee, or to extract the "golden cup", in fact, there are many factors, and each factor is interlinked, it seems that only by having them all can you have perfection. For example, you need a coffee bean that is just past the bean growing period, about 3-14 days from the baking time, water with high mineral content, coffee grinding evenly, a good powder-water ratio, the right water temperature, and so on. However, very often, we are in the filtration process, in fact, it is difficult to control these factors.

Let's put aside the effects of grinding and water quality and water temperature for a while. The time and speed of water passing through the coffee powder layer during extraction directly determine the flavor and extraction rate of your coffee, so if the water flow rate is fast, your coffee extraction may not be enough, the flavor is relatively weak, and on the contrary, it is very slow, and it may also form soaking, resulting in over-extraction, making the coffee flavor become strong, or even miscellaneous flavor. Therefore, as far as a filter cup is concerned, if you can freely switch and change the size and number of holes, and indirectly change the flow speed, perhaps the extraction process will become more adjustable.

December filter cup, one of the reasons for taking the number of "12" is that this filter cup is actually designed with 12 holes, and the disc bracket under the filter cup can be rotated with the filter cup of the funnel. You can understand that the structure is very similar to the packaging of black pepper that is common in our daily kitchen. When it rotates, the hole is exposed and then it is rotated to close the hole. In this way, there are four adjustment modes, from all off to all on, you can change the number of extraction holes according to the situation of different beans, thus changing the filtration rate.

In fact, this method is a bit similar to the smart cup, but it is more efficient and malleable than the smart cup, and you can more easily reduce and increase the holes to help you control the dripping time as much as possible. also try to make up for the shortcomings in other aspects of brewing coffee, such as controlling the flow rate yourself, or other factors that may affect the flow rate and time.

More importantly, you can adjust the number of holes in the December filter cup during the drip filtration process, so you can also intervene in the extraction process to make your coffee extraction accurate to the drip control in the process. Some friends may say, "Why does the hole have a completely closed stage0 option? on the contrary, I think it is because of this mode choice that this filter cup becomes more humane, because when you drop the filter cup to the end, when we often remove the filter cup, it may be dripping on the table, or everywhere else, in short, it is more embarrassing to deal with the residual coffee liquid, but with this function." After you finish the filtration, you can rotate it to a completely closed state, and you can easily take it away and put it anywhere.

Except for stage0, there are different number of hole opening modes, and then the designers also give some suggestions on which mode is more suitable for dripping how much coffee. For this set of reference data, you can choose how many holes you want to brew.

Stage1: suitable for brewing about 10-12 ounces, equivalent to 300-360ML coffee liquid.

Stage2: suitable for brewing about 14-16 ounces, equivalent to 400-475ML coffee liquid.

Stage3: suitable for brewing about 18-24 ounces, equivalent to 500-700mL coffee liquid.

With regard to this project, R & D and design began two years ago, and now it has been sold in South Korea, and designers have also tried various materials in the process, and the final choice is 18-10 stainless steel, which is very durable and resistant to erosion. so it is often used in medical stainless steel or tableware. At the same time, the stainless steel is also coated with PTFE, also known as polytetrafluoroethylene, commonly referred to as "non-stick coating" or "easy-to-clean material".

The price of such a filter cup is about 45 US dollars, equivalent to 310 yuan, which is quite expensive in terms of the price of the filter cup on the market today, but the design concept of "multi-purpose cup" has greatly enhanced the actual use value and application scene of this filter cup, so it is worthy of this price in terms of its application value. At present, there are no purchasing channels in China, which is worth paying attention to.
