dripper

Blue Bottle Coffee dripper + Blue Bottle filter

1. 01Boil 600–700 ml of filtered water.

4. 04Four pours, each about 10 seconds, in a spiral from the center out and back to the center. Start the timer as you begin the first pour.
5. 05First pour: to 50 g, wetting the whole bed. Add a little more if needed. Then bloom about 30 seconds.
6. 06Second pour: 100 g, to 150 g total. Sink the crust so the flow stays even.

8. 08When it has dropped near the bottom again, fourth pour: 100 g, to 350 g total.

• Japan official hand-drip guide. Finished cup is published as 310 ml.
• 50 + 100 + 100 + 100 = 350 g.
• Pours 3 and 4 are visual (when the water has dropped near the filter bottom), not clock times. No timer schedule.
• The US brew guide uses the same 50 / 150 / 250 / 350 g targets with clock times. Those times are not copied here.

The roaster does not specify bean, temperature, time.

medium-coarse (sea salt)

dripper

Chemex

Time

1. 01Start at 50 g coffee and 700 g water, then adjust for the coffee and how strong you like it. Grind medium-coarse, about sea salt.
2. 02Set the Chemex filter with the triple fold on the spout side.
3. 03Rinse the filter and warm the Chemex. Discard the rinse water.
4. 04Add the coffee and shake lightly so the bed is level.
