Quickly calculate brew rations for delicious coffee based on James Hoffmann's recipes

Ultimate Moka Pot

ml g 300 ml

Breakdown

Before: Fill the base with water just below the valve and measure the water. Round off the amount, this is the total capacity of your moka pot.
Optional: If you have a 3+ cups moka pot, you can use an aeropress filter underneath the upper chamber. Wet it slightly so that it doesn't move around.
Ground Coffee: Light roast will weight more than a dark roast, so adjust the amount of ground coffee to fill the filter basket completely but not exceed the calculated value.
1Add 300 ml hot water in the base of the moka pot.
2Add the ground coffee in the filter basket and tap it to evenly distribute the coffee.
3Screw it carefully and put it on heat on low flame. Keep the lid open while it brews.
4At the end of the brew if it starts to angrily spurt and make sputtering noises, take it off the heat and hold the base under cold tap water to cool it down immediately and stop the brew process.
