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.
I've found that a well made cold brew is nearly sweet, it's almost like tea. I don't make that at home though, when I'm in the habit I make big decanters of coffee concentrate and add milk. It's kind of a crime against my digestive system though so I've fallen out of that habit.
