1 Fold the seam of the filter paper, place it in the cone, and rinse with hot water over your cup. Discard this water and place the cone back on the cup.

2 Add your coffee into the filter and keep the switch closed. Pour 50 ml of hot water and hold for 30 seconds. Release the switch and allow the coffee to drain.

3 Continue pouring 50 ml at a time with the switch open, until your total brew is complete.

4 Total brew time should fall between 2:20 and 2:30, depending on your filter paper and grind size.

5 Allow the coffee to cool slightly. Add 1 part tonic to 3 parts brewed coffee. Finish with a few ice cubes and serve.
