The CCD has been my go to single cup brew method for a while. My method, based on Tom's video at SM, is similar to what has been described.
1- I measure out 22 gm of beans on my digital scale and grind a bit coarser than I do for "normal" pour over drip coffee preparations
2- I have a Pino kettle sitting with water at 205*. I determined that 12 oz./355 ml. of water fills the CCD up to the top of the vertical stripes/bars on the CCD so I pour most of that in, start the timer set on 3 minutes, and stir well with a spoon to immerse all the grinds. I then carefully pour along the sides to the top of the bars and cover the CCD with a plate.
3- When the 3 minutes are up I put the CCD on top of my preheated mug and let it drain.
This has worked well for my tastes.
