Coffee | One Roast at a Time — Field Guide
Coffee Processing Explorer
Decode coffee processing labels into calmer, more useful technical interpretation.
This tool is designed to help people move from bag-label language toward clearer process understanding. It is not trying to turn every coffee label into a guarantee. It is trying to make the underlying process more legible than typical coffee marketing does.
Start where you are
This explorer is built as a field guide, not a verdict machine. Choose the doorway that matches what you need today.
Understand the process path
Use the journey map to see where a method becomes meaningfully different.
Decode a label
Translate a process name into a calmer technical interpretation and better follow-up questions.
Compare two methods
See where two labels overlap, diverge, and leave important questions unanswered.
See ORAT examples
Follow how process shows up in ORAT’s own roasting context without pretending it explains the whole cup.
Processing journey map
From ripe cherry to green coffee. Each process represents a set of decisions — about infrastructure, skill, climate, labour, and intention. Select a process below to see what happens at each stage, what it may suggest, and what it does not guarantee.
Decode a coffee label
Type what's on your coffee bag. This tool will try to identify the origin, variety, process, and decaf method — and flag what each element does and does not tell you.
Prototype decoder — keyword coverage is limited. Origin, variety, and process terms are matched against a growing list. Expand data/processes.js to add more.
Compare two processes
Select any two processing methods to see a side-by-side breakdown of what happens, what it may suggest, and what it does not guarantee. No process is presented as superior. Execution, origin, variety, drying, and roast approach all shape the cup alongside process.
Processing myths worth knowing
Some processing shorthand has become so common that it shapes expectations before the coffee is even tasted. These are practical corrections — not coffee snobbery. They are here because inaccurate expectations make it harder to assess what is actually in the cup.
ORAT roasted examples
Coffees ORAT has roasted on the Gene Café CBR-301, organised by process. These are placeholders until connected to the Green Bean Ledger.
