Idk if I've been committing a coffee crime, but I've been doing this for about 6 months now.
18g (preferably light roast) coffee.
Grind at 16 clicks Timemore C2.
00:00 (closed):
pour 350ml water, then coffee, stir
05:00:
Open valve and drawdown
Add 300g ice. Enjoy.
I've tried various grind levels and got similar results. The only change was the drawdown time, but if you factor in the temperature when adding ice, it tastes basically the same. I've yet to do an A/B test and all observations are compared to the previous day's brew.
I don't like hot brews or darker coffee so ymmv :shrug:
