Bring at least 600 grams (20 oz) of water to a boil. Grind 30 grams of coffee (3 tbsp) to a coarseness resembling sea salt. To enjoy the nuanced flavor of a single-origin coffee that is lightly roasted, we recommend less coffee: 23 grams for every 350 grams water.
Place a filter in the dripper. We recommend wetting the filter with hot water and then dumping the water before proceeding with brewing. Add the ground coffee to the filter and gently tap it to level the surface of the grounds. Place the brewer on a carafe or cup, place this entire set-up onto a digital scale, and set it to zero.
There will be four pours total for this coffee preparation. This is the first, and the most magical, because it is when you will see the coffee “bloom.” As hot water first hits the grounds, Co2 is released creating a blossoming effect—the grounds will rise up en masse. Start a timer. Begin pouring water slowly over the coffee, starting at the outer rim and moving in a steady spiral toward the center of the grounds. Stop pouring when the scale reaches 60 grams. Make sure all the grounds are saturated, even if you need to add a little water. The pour should take about 15 seconds. Give the coffee an additional 30 seconds to drip before moving on to the second pour.
