Japanese iced coffee!
- Take half your total pour over water weight and put that amount of ice in the bottom of the Chemex.
- Grind the usual amount of coffee for your Chemex brew.
- Brew with whatever method you usually do but half the water weight for each pour (so you end up with the same amount of water as usual when you add the ice)
Instantly cold but full strength because the ice doesn't water it down when it melts!
