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.

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.

Use this to brew amazing coffee every time. It works exceptionally well with Hario V60 & Origami drippers. Origami being my favorite! You can achieve great results with flat bottom Brewers also.

Works well! use it every morning. Would appreciate having a fahrenheit setting for the target coffee tempts. My Cuisinart kettle is xenophobic and won't let me use Celsius.
