1. Place all ingredients in a sterilized 1-pint mason jar. Screw cap on and shake daily for 3 to 4 weeks.
2. Filter the mixture two times, reserving the solids and the liquid. (Bill first strains the mixture through a fine-mesh strainer and then strains again through a gold coffee filter. He says a paper coffee filter leaves a bad taste). You should have about 240 ml (1 cup) of fluid.
3. Add 125 ml of water to the solids and place in a saucepan. Bring to a boil and then remove from heat. Steep for 10 minutes to make a tea. Filter the tea through the same two-stage filter, discarding the solids.
4. Add 80 ml of the tea liquid to the reserved bitters liquid. Let sit 7 to 10 days for flavors to blend.
