Okay so I have 6 gallons of american oatmeal stout that I am going to split in to two 3 gall batches and add coffee to one when I bottle it. I plan on cold brewing coffee and just want to make sure I do this right.
I am going to use 2.5oz by wight of coffee to cold brew with. How many ounces of water should I use? I have read a 4:1 water to coffee ratio but what are the measurements? Are they both weight?
I am going to boil the water and cool to room temp then add coffee and sit over night then add when I bottle.
I cold brew my iced coffee(that I drink), and I add 4 tablespoons per 16oz or so. I just let it soak in a french press in the fridge for about 8-12 hours then strain. You get the beautiful coffee flavor without the bitterness.
