A calm doorway into the project.
Coffee | One Roast at a Time is a practical home-roasting project built around the Gene Café CBR-301, real roast records, simple tools, and careful learning in public.
What this is
It is not a roasting school. It is not expert instruction. It is not coffee theatre.
It is a growing record of learning carefully in public, one machine, one roaster, many real roasts, written down as they happened.
Choose your path
I am new to the project
Start with the Guide. It captures the stable patterns without pretending they are universal rules.
I own a Gene Café CBR-301
Go to the CBR-301 start page and the JSON Roast Report. They are the most practical entry points for machine-specific learning.
I want the actual roast records
Browse the Notes archive. These are not recipes. They are records of what happened, what seemed to matter, and what remained uncertain.
I want tools
Use the Gene Café JSON Roast Report, the water calculator, and the cupping form to support repeatable notes.
I prefer video
Use the video archive for practical explanations, roast examples, machine-state updates, and project milestones.
I want wider coffee context
Around the Bean tracks coffee signals from crop to cup, with context, caution, and links back to original sources.
A useful first reading path
How to read the project
Observation first, interpretation second.
The best parts of the site separate what was observed from what I think it might mean. That matters because home roasting is full of tempting shortcuts, especially when a graph looks more precise than the roast actually is.
