I had great results using 0.60lbs of a medium roast (drip grind), 3L of water (no ice) and about a 12hr target brew time. I wanted a 'concentrated' coffee so when it was finished brewing, I would add a bit of water to the brew and serve. It tastes much better that way, anyway! I use a different Toddy now to keep up with the iced coffee demand, but the Yama sure does look nice!
