Undrinkable coffee??? try caffenol for developing film
(formulas in the alternative forum here)
I did a lot of that staining with tea and coffe... it was fun, and even after 10 years the pics look good (they are framed @my mom's house)
Just prepare a very strong tea batch (6 or 8 bags in 1l), let it cool down to luke warm and then put your wet prints in there until the tone you want is achieved. I liked to wash after toning for a couple of minutes.
I tried toning once with mint tea but the green tone faded quickly
