Usually, I make around 300mL of iced coffee. Here's how I do it:
- Weigh 100g of ice cubes, put in the carafe, and store in the freezer.
- I use 18g of medium roasted arabica, and grind it medium coarse (similar to pour over size)
- Put the coffee ground in Hario Switch and add 200g of boiled water.
- Stir and let it brew for 5 minutes.
- Decant the coffee into the carafe (nr. 1).
- Give a good stirr until all the ice cube melt, and enjoy it directly or put in the fridge for later.
I hope it helps.
Obviously a matter of opinion. Or maybe method. My coffee does not have a stale oil taste. But coffee brewed hot and then iced, for me, it accentuates the bitter.
