For Light Roast "T-92"
Achieves a fruity, aromatic, and clean cup.
Works best with 92℃ of hot water.
There is no crepe on the inside, and the surface area is smaller compared to the other two. The filter catches micro powder with less amount of space, gently blocking and holding the water flow to extend the contact time, extracting as much aroma as possible. Once the extracted liquid filtered through, the crepe on the outside lets it flow smoothly. The high efficiency in catching the micro powder on the inside of the filter makes a very clean cup.
For Medium/Medium-dark Roast "T-90"
Achieves a rich, well-balanced and fragrant cup.
Works best with 90℃ of hot water.
Crepe With the crepe on both sides, it allows a speedy brew. Thanks to the crape, the surface texture catches the micro powder while maintaining enough surface area free from micro powder that lets the water through until the end. Works best with 90℃ of hot water, to make the most out of medium/medium-dark roast
For Dark Roast "T-83"
Maximises the body and mellow richness of dark roast.
Works best with 83℃ of hot water.
This one also has crepe on both sides, but the height of the ridges are set low. The surface area is larger than one-sided crepe paper, therefor it catches micro powder with bigger area. For the first half of the brewing process the filter has less micro powder caught on the surface, and allows smooth and speedy water flow. As the micro powder start to accumulate, it holds the water flow and gives the brewing speed a perfect rhythm to extract the maximum sweetness and thick body.
