Cold brew in a Hario bottle.

Let’s make coffee.

1. 01

   Grind and fill

   Grind the coffee coarse, add it to the filter case, and attach the case to the silicone top.

2. 02

   Add the water

   Fill the glass base with 750 g of water, up to the bottle’s top grey square. Lower the filter assembly into it.

3. 03

   Seal and steep

   Seal, shake gently, and leave at room temperature for up to 18 hours.

4. 04

   Remove the grounds

   Shake gently once more, remove the filter case, and replace the top. Keep the finished coffee sealed and refrigerated.

Record the hours, not just “overnight”

Save the start and finish times. That lets you compare two batches without guessing how long each spent steeping.
