Thats the one thing ive noticed about t he bunn is it brews super fast, not much time for extraction, although you can control that with grind I am betting as sea said. Even though it requires you to be there, that is the one thing I like about the TV is you can close it off, let the ground bucket pretty much fill to the top then then open and drain out, repeat till done. I wonder if there is some way you could rig a bunn for that?
