Fellow EKG Kettle

The Design Logic Behind the Kono Dripper Most pour-over enthusiasts struggle with **bypass**—water that skips the coffee bed and slips through the side of the filter. The Kono Dripper solves this through a unique rib design. Unlike a V60, which has ribs running from the top to bottom, the Kono is smooth at the top. This allows the paper to suction tightly against the wall, forcing water through the coffee rather than around it. Only the bottom third contains ribs, creating air pockets that allow for a controlled, partial bypass. This design ensures that every drop of water does its job before exiting the cone. Tools and Materials for the Perfect Brew To replicate these results, you need precision tools. I recommend the following: * Kono Meimon Dripper * Cafec Medium Roast or Hario Untabbed filters * Fellow EKG Kettle for temperature control * 12g of coffee (Medium-Fine grind) * 200g of high-quality water * A chopstick or stir stick I prefer using Cafec filters because they absorb fines effectively without clogging, maintaining a fast flow rate even with light roasts. Recipe One: The Double-Bloom Sweetness Profile This recipe focuses on maximizing extraction and sweetness, ideal for gassy, fresh beans or high-acid profiles. 1. **Preparation**: Wet the filter under a faucet to ensure a perfect suction against the walls. Add 12g of coffee and use a chopstick to create a small center divot. 2. **First Bloom**: Pour 30g of water at 99°C from a height to create **turbulence**. Swirl the dripper vigorously to saturate all grounds. Wait until the 1-minute mark. 3. **Second Bloom**: At 1:00, pour another 30g and swirl again. This breaks the crust and allows trapped CO2 to escape. Wait until 2:00. 4. **Main Pours**: At 2:00, pour 70g in small circles behind the center. Give it a gentle **Hoffman spin**. At 2:45, pour the final 70g to reach 200g. Finish with one last gentle swirl to level the bed. Recipe Two: Accentuating Bright Acidity If you want to highlight the vibrant, fruity notes of a washed coffee, use this lower-agitation method. 1. **The Long Bloom**: Start with a 40g pour at 99°C and a vigorous swirl. Wait a full 2 minutes. As Jonathan Gagne notes in The Physics of Filter Coffee, a long bloom allows water to penetrate the interior of the grounds for better diffusion later. 2. **Concentrated Pour**: At 2:00, add 100g of water with turbulent flow. Swirl gently to level the top layer. 3. **Final Stretch**: At 2:45, pour the final 60g. This faster drawdown limits contact time, preserving bright acidity and preventing bitterness. Tips and Troubleshooting If your brew tastes bitter, drop your temperature to 97°C after the bloom. The Kono's plastic material retains heat better than ceramic, so you don't need to fight temperature loss. If the flow stalls, check your filters. The Hario Untabbed filters are thick and resilient; if you use a thin, tabbed filter, you may experience clogging from coffee fines. Conclusion: Consistency Without the Fuss The Kono Dripper isn't just another gadget; it's a reliable workhorse. By eliminating the variables of massive bypass and providing a stable thermal environment, it delivers a repeatable, high-clarity cup every morning. Whether you seek the deep sweetness of a double bloom or the sharp pop of a long-bloom acid profile, this dripper makes the process effortless.
