Cối Xay Cà Phê Thủ Công ROK GrinderGC

ROK was born from the minimalist philosophy and pure handcrafted spirit of the UK. Instead of chasing automation, ROK believes that espresso brewing should be a direct experience—where the barista feels the pressure, the flow, and the response of the coffee with each hand movement. ROK doesn't create machines to "replace humans," but rather tools to help people better understand espresso—simple, durable, and true to the essence of extraction.
ROK GrinderGC is a manual coffee grinder for users who want to control grind size through real hand feel, without relying on electricity. The vertical grinding action creates a smoother and more stable movement compared with common horizontal mechanisms. The grinder is crafted from cast aluminium and glass composite, combined with hardened SUS420 steel conical burrs. Its adjustment range covers espresso-fine to cold brew coarse, making it suitable for multiple brewing methods. The product includes a bamboo grounds cup, silicone hopper lid, and comes in a plastic-free gift box.
