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.
Going to have to disagree: cold brew made by hot coffee is generally bad.
I put coarse ground beans into a French press and then drink it the next day (18 hours later). It's the laziest method. You just make tomorrow's coffee when you are done with today's.
How is iced coffee bad? If done right it is just normal coffee but cold. On the other hand, cold brew almost always has a slight stale oil taste which I can't stand.
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.
