So I know the accepted practice for cold brew is to do a coarse grind, and to brew somewhere between 8-24 hours depending on whether you’re doing it at room temperature or in the fridge.
But is this really necessary? Could I just use a finer grind and brew for less time? I’m asking because when you grind coarse, you end up having to use a lot more coffee beans (mass) than you would for the equivalent volume of any other type of coffee.
For context, I’m using a coffee sock which is just a glorified reusable coffee filter, so I don’t think that grind size is going to impact filtration that much.
Cold brew is my go to for gifted beans or trying a new roaster/bean that turns out I didn’t terribly enjoy. I’m not wasting the beans and because it lacks complexity (and I’m going to hit it with a little sweetener and cream anyway lol) I can still end up with a very drinkable cup.
