Each filter cup will have a different impact on the extracted flavor due to its shape, filter holes and grooves. Each filter cup has its own design advantages, which are basically based on controlling the water flow rate, ribs and exhaust. Using different filter cups can give the same coffee beans different taste sensations. Today, Qian Street is usedV60Use the YASUKIYO wooden filter cup to brew the same coffee beans and see what the difference is.
01| Introduction to filter cup
The design of the V60 focuses on the speed at which the water level drops, allowing better extraction of coffee powder particles. The appearance is the same as a conical filter cup, but the internal ribs are designed with a curved vortex structure to help speed up the water flow and extend from the bottom to the top, indicating a smooth exhaust effect. The curved ribs increase the water flow path to increase the contact time between coffee particles and water. Generally speaking, the V60 mainly focuses on flushing, controlling the speed and direction of the water flow, allowing the coffee powder enough time to absorb hot water and fuse the soluble substances with the water.
The YASUKIYO wooden filter cup is cut from a whole piece of wood and polished by hand. The wood is partially thickened and can be held directly without burning your hands. The wood is cut horizontally along the grain, producing greater durability. The water outlet hole of the YASUKIYO filter cup is larger than that of the V60. Although it is a conical filter cup, the ribs inside the filter cup are not the usual threads or vertical ribs, but parallel ribs in a circle.
In order to compare the impact of the two filter cups on the flavor and taste of the same coffee beans, the same brewing technique was used, the same time and amount of water were used for steaming, and the same amount of water was used to complete the brewing, to achieve the greatest possible consistency and rigor in the experiment.
02| Brewing experiment
Take [Front Street 2013 Yunnan Small Iron Pickup] as an example
V60 brewing data
Water temperature: 90℃
Powder amount: 15g
Grinding degree: EK43s scale 10 divisions (medium-fine grinding)
Gouache ratio 1:15
Brewing method: Steam 30g of water for 30 seconds. In the first section, add water to 120g. The water flow should be vertical. The small water flow should circle around the center in a coin-sized circle. In the second section, add water to 225g. Increase the speed of the circle slightly. The small water flow should go around the outer circle.
Time: 1'55"
Flavor: dark chocolate, raspberry, cream, long-lasting sweetness, rich taste and rich flavor.

03| Experimental conclusion
The design of the V60 filter cup is pure flushing, using spiral ribs to create a twisting function to increase the extraction amount of soluble substances. The curved design increases the time that water stays in the particles. V60 can not only increase the concentration of water flow, but also make the coffee powder more concentrated, so that it can absorb water more evenly during steaming. However, the flow rate is relatively fast and it is easy to under-extract.
ButIf we choose the V60 filter cup and match it with reasonable parameters, it will be easier to brew the layered coffee. It is recommended to use Front Street Jade Green Label Geisha (jasmine, cantaloupe flavor), Front Street Mozart (raisin; pineapple flavor), Front Street Kaffa Forest (floral flavor; orange flavor).
The design of the YASUKIYO wooden filter cup combines the characteristics of the kono filter cup and the V60, with a large water outlet hole and transverse ribs. The groove design of the transverse ribs is not only for aesthetics, but also to reduce the water in the upper layer from escaping from the edge, slow down the water flow, lengthen the contact time between water and powder, and extract coffee more evenly. This is based on the design principle of the Kono filter cup.
Therefore, it is best to pair it with low-acid, medium-dark roasted coffee beans such as Front Street Blue Mountain No. 1, Front Street PWN Gold Mandheling, Front Street Brazilian Semi-Saturated, and Front Street Colombian Cymbidium, which can fully reflect its mellowness and solid taste.
The filter hole design of the YASUKIYO wooden filter cup speeds up drainage, making up for the shortcomings of poor drainage caused by the lack of exhaust ribs. However, the fit of the filter paper cup is poor and there are many bubbles.
