Tri-Spin FS Flat Dripper with Stand 1. Rib Structure · Uniform Extraction The interior features 20 precisely engineered ribs that prevent dripper paper deformation, reducing variables during the coffee brewing process to enhance extraction uniformity. The thoroughly tested and validated wall angle maintains a brisk flow rate while simultaneously allowing baristas to use a finer grind. This increases the extraction yield, preserves the coffee's layered complexity even in faster brews, and delivers a distinct, well-defined flavor profile. 2. Tri-Spin Hollowed Base · Efficient Extraction The tri-spin hollowed design at the base disperses the water's exit points, effectively mitigating the risk of center clogging. This not only increases extraction efficiency but also ensures water passes evenly through the ground coffee layer, reducing the probability of localized over-extraction with larger coffee doses and enhancing overall brewing stability. 3. Wulong Weave Texture · A Fusion of Form and Culture The exterior texture is inspired by a unique Chinese bamboo weaving technique called "Wulong Weaving." The Wulong bamboo weaving texture is applied to the exterior wall of the dripper, creating a geometrically appealing pattern of interwoven "回" characters. This integration of tea culture elements with coffee hardware endows the contemporary "Xuanwu Flat-Bottom Dripper" with a visual language rooted in Chinese culture. Fits 185 wave filters.
