Prepping for the Perfect Coffee
1. The Equipment
Necessary Equipment: Coffee dripper, paper filter, carafe, scale, kettle
Optional Equipment: Grinder
2. The Coffee
Tetsu created the 4:6 Method based on using coarsely ground coffee beans. Generally speaking, either coarse grounds (brighter flavor) or fine grounds (stronger flavor) can be used. If you want a lighter brew, use a coarser grind; if you want a thicker brew, use a finer grind.
3. The Water
- Use purified, soft water (30–50 mg/L hardness is recommended).
- Avoid using freshly boiled water, as the water temperature is too high and tends to produce a bitter taste. The ideal temperature is:
- It's best to use a kettle with a narrow mouth.
What Is the 4:6 Method?
The 4:6 Method is a revolutionary hand-drip formula invented by Tetsu Kasuya that won him the coveted title as the 2016 World Brewers Cup Champion. The method gets its name by how the hot water is divided during the pouring stages—40% and 60%—which allows you to adjust the flavor and concentration of the coffee.
By following this method, you can control the taste simply by adjusting the formula rather than relying on experience, technique, or luck.
Tetsu created the 4:6 Method to make it possible for anyone to easily brew delicious coffee.
Not only is it easy to master, but the method is also practiced and recommended by top baristas and coffee lovers around the world for its ability to consistently produce excellent results.
When the 4:6 Method was introduced at the World Brewers Cup, it was recognized for its simplicity, innovation, and excellent taste. As a result, Tetsu won the competition and became the first Asian world champion.

Breaking Down the 4:6 Method
Basic Formula for Brewing
The easiest way to remember the 4:6 Method is to multiply the weight of the ground coffee beans by three to find out how much water to use for each pour. Then multiply that number by five to find out the total weight of hot water you will need.
For example, if you're using 20 g of ground coffee beans, you will pour 60 g + 60 g + 60 g + 60 g + 60 g of hot water for a total of 300 g.
Each pour should be timed so that the hot water has almost completely passed through the filter before pouring again. This is the key to extracting a rich and robust flavor, even with a coarse grind.
Timing Each Pour
0:00 Pour 60 g
0:45 Pour 60 g
1:30 Pour 60 g
2:15 Pour 60 g
2:45 Pour 60 g
3:30 Remove the coffee dripper
Tetsu suggests adjusting the coarseness of the ground coffee beans to match the timing above.
Discover Your Own Perfect Cup
What makes specialty coffee so appealing is its complex and rich taste. However, it's only when it has a clean flavor profile that you can fully enjoy it. It's easy to brew coffee with the ideal taste by grinding it coarsely. So, be sure to weigh it well and try to imitate the extraction formula described above.
Philocoffea believes that this method is ideal for all types of beans. However, there are still many other ways to brew amazing coffee. So, why not try using the 4:6 Method as the foundation to explore other extraction methods. From there, you should be able to discover your own way of making the perfect cup.
