A starting point - adjust to your beans.
The water temperature is the widest disagreement in this whole book: the national coffee association teaches around 65 degrees, the largest domestic roaster over 90. That is not carelessness - the thick nap holds heat and slows the flow so much that coffeehouse practice pushes the temperature down where paper drip pushes it up. The grind is disputed just as badly, which is why there is no figure for it here.
How to go about it
Boil a new cloth for at least twenty minutes with a little coffee in the water before you brew with it.
Hold the cloth by its handle, add the grounds, and wet them lightly for about twenty seconds.
Pour in several small additions rather than one stream, keeping the bed just covered.
Rinse the cloth afterwards and store it submerged in water in the fridge. Left to dry, it turns rancid within a day.
