As a filter coffee enthusiast, I recently upgraded from the Timemore C2 to the Kinu M47 Classic for my pour-over setup, primarily using the Hario Switch. The difference is night and day. The Timemore C2 was a solid entry-level grinder—affordable, decent consistency—but its 38mm burrs struggled with uniformity at coarser settings, limiting my brews. I’ve since donated it to share with colleagues at the office, where it’s still churning out decent cups.
The Kinu M47 Classic, though, is a masterpiece. Its 47mm Black Fusion-treated conical burrs bring precision and clarity to my Hario Switch pours, revealing vibrant florals and crisp acidity the C2 couldn't touch. The stepless adjustment (0.01mm increments) pairs perfectly with the Switch's versatility. At 0.95kg, its stainless steel build dwarfs the C2's plasticky frame, and grinding is buttery smooth with four ball bearings, though its a workout compared to the Timemore's lighter crank.
The Hario Switch is my playground for techniques like Tetsuya Nakajima's "The Devil" method–full immersion for 3-4 monites with a high dose (e.g., 20g coffee to 200g water) before a slow drip release, yielding a bold, syrupy cup. I also tweak immersion times (1-2 minutes) for lighter, tea-like brews or use it as a straight dipper. The M47's grind consistency enhances every approach, coaxing out nuanced flavors the C2 muddled.
The Kinu’s construction is a marvel of engineering. Crafted in Germany, its body is machined from high-grade stainless steel, giving it a robust, premium feel that screams durability. The 47mm burrs, treated with a Black Fusion coating, resist wear and maintain sharpness far beyond standard steel. Four precision ball bearings ensure the crank glides effortlessly, minimizing wobble and maximizing grind uniformity. The thumb rest and ergonomic handle make the manual grind less taxing, while the adjustment knob’s micro-precision clicks inspire confidence. It’s a stark contrast to the C2’s simpler, less refined build.
Priced at B$539 versus the Timemore C2's ~B$80, it's a leap, and I miss the portability. But for my pourover setup, the richer body and clarity are worth it. The Timemore C2 now fuels office coffee breaks, while the Kinu reigns at home, making every pour a ritual.
