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.
