There are actually a lot of coffee filter cups on the bar in Sit Down Plz Roasting, but the more commonly used is the Sanyo Youtian ceramic filter cup from Japan, the specification is 102 red limited edition. The origin of this filter cup is not small. It is Mr. Taguchi, the Japanese "god of coffee". He runs the only designated coffee filter cup in the Baja Cafe. The traditional trapezoidal structure design is divided into three sizes: small, medium and large, and the discharge holes are divided into 1, 2 and 3 according to the size. This is through the number of holes to achieve the effect of adjusting the flow speed, so that different sizes of trapezoidal filter cups can be consistent in the extraction time, which is a rare concept in other brands.

The Sanyo filter cup is developed according to Mr. Taguchi's hand-flushing concept. By inheriting the 400-year-old Youtian firing process, the ceramic surface is smooth and meticulous, making the water flow extremely smooth, and at the same time, it also has a strong and durable special shape. In particular, the concave and convex water diversion groove extends all the way to the bottom outlet, so that there is enough gap between the filter paper and the bottom, so that there is no stagnant water, and the original filter paper will be more perfect.

After watching the film of Chien Shiwei's demonstration of brewing and cooking, there is a very important key, that is, after the steaming is over, he will inject an average of 80 grams of water in 15 seconds each time, and the injection will be divided into three times in sequence, with an interval of 15 seconds. Four key factors affecting hand-brewed coffee have been mentioned before, one of which is "speed", that is, the speed of water injection, which also involves the control of the size of the water column. In fact, it is very difficult for us to accurately describe and control the size of the water column, but it can be achieved through the technique of "injecting a fixed amount of water within a fixed time".

The complete boiling time is about 2 minutes and 30 seconds, the concentration of TDS measured by instrument is 1.37, and the extraction rate is 19%. Jian Shiwei also mentioned: "if the exhaust period is not over, the concentration will generally fall in the range of 1.27-1.31 within a week after baking." This shows that coffee beans with more complete exhaust are easier to extract.

The commonly used hand punching pot made of Kalita crane mouth copper has a capacity of 700ml.

When hot water is injected into steaming, it can be found that the coffee powder will expand and exhaust gas after absorbing water. Generally speaking, the degree of expansion is related to the depth of baking and the freshness of coffee beans.

As to why he chose this Sanyo terraced ceramic filter cup, Sit Down Plze Roasting owner and bean baker Chien Shiwei has a unique view. "at the beginning, the idea was that when you need to brew three cups of coffee, the alternating process between the pot and the pot will not cause too much pressure because of the rapid flow rate, so I chose the ladder filter cup." It can be seen from here that he was positioned to make coffee by hand as the main business force.

He also said. If you want to make an established mellow taste impression, you can also make a bright sour coffee with a rising aroma by adjusting the proportion, grindness or water temperature details.

"among many trapezoidal filter cups, the reason why I finally chose Sanyo Tian Burning filter Cup is that I like the detailed surface of its grooves, the size of objects, the strict quality of materials, and the style of sincere price. it's hard not to give a thumbs up with a hard base that is resistant to fade." Holding the filter cup he had just finished, Chien Shiwei smiled proudly and said that he felt like a hero and cherished a hero.
