We have the Toddy T2N Cold Brew System. We used it a couple times already, love it, love the coffee it makes and here we have twelve ounces of course ground coffee. The process you use with this is you put in the filter and the stopper underneath then you put in a cup of water, six ounces of course ground coffee, three cups of water. Then the other six ounces of coffee, we have twelve total ounces of coffee. You wait five minutes. We just waited five minutes. Here come the last three cups of water and you kind of do in a circular fashion. And you don't want to shake or disturb the coffee but you do want it all wet, so we just take a spoon and gently kind of push it to make sure it gets wet and that's pretty much it. So again it was 12 ounces course ground coffee. Seven ounces total of water.
