Nautilus Slow Flow Immersion Coffee Dripper [Qing Glaze] (1-4 cups)

"Slow Flow Immersion Dripper" The Nautilus dripper features a biomimetic design, with "ribs" shaped to mimic the spiral lines generated by the rotational curve of a nautilus shell. This dual-spiral rib design enhances water agitation. When the water level reaches about 60-70% of the dripper's height, the flow rate slows, extending the contact time and surface area between water and coffee grounds, resulting in a rich and sweet coffee flavor. The Sanshing Four Seasons Blue and white studio's works have consecutively won the "Cultural and Creative Boutique Award" and the "Golden Pin Design Award" for two years. Our ceramics pursue the unique, rustic feel of handmade craftsmanship, created by artisans using an original blue and white dyeing technique. Our studio space has also received the German iF Design Award and Japan's GOOD DESIGN AWARD.
