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.
No, I wrote off the room temp idea since coffee can spoil easily at room temp.
This is my general method, but I do brew for only 8-12 hours instead of a full 24. I did recently do a batch in the fridge and noticed the flavor profile was different, so I might have to switch over. So many variables… confusedmathlady.gif
