Heat filtered water to 90–96°C, set up your dripper with a filter on your mug or carafe, rinse the filter to remove paper taste and prewarm, discard rinse water, place everything on the scale, and tare to zero.
Weigh 20 g of coffee beans, grind to a medium-fine texture slightly coarser than table salt, then pour the grounds into the rinsed filter and gently level the bed.
Zero the scale again, start the timer, pour about 40–45 g of hot water to wet all grounds for the bloom, and let it sit for 30–45 seconds until the coffee swells.
Slowly pour the remaining 280 g of water in stages using a gooseneck kettle, maintaining a steady circular motion from center outward and back, and aim to complete pouring within 2–3 minutes for a total brew time of 2.5 - 3.5 minutes.
Allow the dripper to finish dripping, then remove it and discard the filter and grounds, swirl your coffee to mix, inhale the aroma, and pour into your cup to enjoy.
Rinse your dripper, carafe, or mug, clean your kettle if needed, and keep your brewing gear fresh for the next perfect cup.
