I have heard great things about cold drip but haven't tried it yet. I have to use way too many grounds to get good flavor through my french press. I think. Been a while since I have used it. We are currently using a drip but I don't like it. My parents have the Kuerig but I can't get it strong enough for the quantity I drink.
I would still like one though. someone had shown me a cool type of brewing system the other day but I cant' find it now.
