- Its example maps “a bit sour” to grinding finer by one number, using a Niche Zero recipe with dose, yield, and brew time.
Field notes
The site lays out a progression from a simple grind-and-taste routine to more detailed brew logging, with ratios, timers, freshness history, and water temperature in its Enthusiast level. Its Pro level is described as adding pressure, pre-infusion, bloom, TDS, charts, and CSV export. The page also says recipe links contain only the recipe and the name a user chooses to show.
