Nothing is filled in with a guess here. A time is published only once it has been read off a primary source, because a plausible wrong time costs somebody a roll they cannot reshoot.
Reuse
Checked 21 October 2026
The maker’s sheet doesn’t say whether it can be reused.
Recipe
Mixed from raw chemistry
Mixed at home from instant coffee, washing soda and (for Caffenol-C) ascorbic acid. Proportions vary by variant — record the exact formula on the dilution before citing a time against it.
