Videos
Practical coffee learning, shown calmly.
A curated video archive for Gene Café CBR-301 roasting, machine behaviour, roast decisions, cup results, tools, and the wider Coffee | One Roast at a Time project.
How these videos fit the project
The videos show the same learning loop as the written notes: what I expected, what the machine did, what I recorded, what the cup suggested, and what I would try next.
They are intentionally observational rather than performative. The aim is confidence through repetition, not perfect tasting language or fake certainty.
Good places to start
Start here
New to the Gene Café CBR-301
Start with baseline thinking before chasing profiles, curves, or tiny control changes.
Long view
After 100 roasts
A calmer long-term view of what the roaster suits, where it frustrates, and how expectations changed.
Tooling
The JSON Roast Report beta
How exported roast data became a useful learning report and planning helper.
Decision point
Stopping a roast
A practical example of why first crack, colour, time, weight loss, and judgement all need context.
