A new coffee brewing theory created with the concept of "easily-brewed delicious coffee for everyone." Divide water into a ratio of 4 to 6. Adjust taste with the first 40% of water and density with the remaining 60%.
The point is to use coarse grounds and make the second pour after the water from the first pour completely drips through.
The conventional rib shape of the V60 dripper has been customized. It slows water down for better extraction of coffee, making it possible to brew stronger coffee even with the same amount of coarse grounds.
