Roast 14 — Ethiopian Natural Drying, Browning, Development CBR 301

Описание: This video documents Roast 14, a static, end-to-end reference roast on the Gene Café CBR-301, filmed with a fixed camera and minimal intervention.
The focus here is not optimisation or instruction, but observation, watching how the roast moves through drying, browning, and development, and noting what signals are reliable in practice.
This roast forms part of an ongoing exploration into first crack audibility on natural-process coffees on the Gene Café. Rather than forcing decisions based on sound alone, the roast is guided by colour, aroma, time context, airflow behaviour, and overall progression.
No flavour claims are made in this video. Evaluation happens later through diagnostic cupping, deliberately separated from the roast to avoid bias.
Roast context
• Roaster: Gene Café CBR-301
• Coffee: Ethiopia — Natural process
• Batch size: 250 g
• Style: Reference roast (static camera, observational)

Why this format
Most home roasting happens quietly, with uncertainty.
This video aims to show what a normal roast actually looks like, without performance, recipes, or guarantees.
Part of the series
This video is part of Coffee | One Roast at a Time — a project documenting learning through repetition, restraint, and honest observation rather than expertise or optimisation.
