What is the coffee & water ratio when cold brewing? What is the proper coffee to water ratio for a cold brew? I did mine with 100grams of coffee (an Ethiopian light roast) and a liter of water, and brewed for about 12 hours. It tasted good to me, but my friends said it's too acidic for them, hence I find it acidic in a way that the sweetness is present and with clean finish.
It depends where you look. When you create the concentrate some people say 1:2, coffee and water, some say 1:1. It really depends on how you like it.
