I had a PBR hard coffee last weekend and I gotta say it was pretty good, It's a little sweet and it needs more of a coffee flavor. I decided to give it a go this friday...I'm making 2 gallons of dark roast cold brew coffee, adding 3 gallons of water to make a 5 gallon brew. Adding 4lbs of corn surgar, 2lbs of lactose. Hopefully this will turn out, of course we will be tasting along the way. Has anyone else tried this and if so what did you do?
