About this app

This application is under development, additions are planned as an explanation of the 4:6 method I am interested in your comments or ideas to continue to improve this application.

Prepare a speciality good coffee following the 4:6 method of Tetsu Kasuya, using a Hario V60 dripper, Chemex, Blue Bottle, Origami or any other filter dripper.

The 4:6 method is a recipe of Tetsu Kasuya who won the 2016 World Brewer's Cup in Dublin, Ireland.

The method consists of dividing the volume of water into two parts, one of 40% and the second of 60%. The first part is poured in two times, this step will determine the balance between the acidity and sweetness of your cup. For the remaining 60%, the number of pours will determine the strength of the coffee.

The application generates for you a recipe according to your desires, define the coffee you want, the strength, the quantity, follow the recipe and enjoy.

Ratings and reviews

Such a useful app! Helped my technique and opened my eyes for different roasts. Edit : My only complaint is when it comes to editing the ratio. The app has trouble when it comes to manually changing volume for water and grounds. It would also be much easier to manually type the ratio instead of a slider.

I'm not yet convinced that the Ketsu method produces better coffee, especially considering how time consuming it is. I'm especially not convinced that minor adjustments to the way you pour, without adjusting the grind size or ratio, will make the coffee sweeter or more acidic. However, I am convinced that this is a really well designed app and I highly recommend it if you want to experiment with this method.

I've been using this app for a few years and it's very convenient. After trying many different recipes I always come back to Tetsu. You can choose your number of pours, sweet or bright profile, ratio, grams etc. It calculate everything automatically and the result is easy to read.
