Cerapotta Dripper Immerse yourself in the world of exquisite coffee with cerapotta's unique coffee filter. Crafted from Japan's porous stone, this minimalist marvel refines water and coffee flavors. Say goodbye to wasteful paper filters and unlock the true essence of your favorite brew.Hand Crafted in Hasami, JapanMaterial: Porous ceramicHow different with the other porous filter?1. MaterialsThe main ingredients of cerapotta are: clay + alumina ceramic + proprietary material. Alumina has positive effect on taste and aroma by allowing coffee to be extracted without hindering its original flavor. The proprietary material burns out during firing (at 1,200°C), and the burnt-out part creates porosity. 2. Molding MethodCerapotta is molded using a potter's wheel, with each piece being handcrafted by artisans, resulting in consistent shaping with minimal irregularities. 3. MaintenanceWhen coffee brewing becomes slow, place the ceramic pot in boiling water for about 10 minutes to remove any clogs.
