Gene Café CBR 301 - Coffee Roaster - Bluetooth

The Gene Café CBR-301 roasts up to 300 g of green coffee at a time in a see-through Pyrex drum, using indirect hot air rather than a hot surface. The drum turns off-axis so the beans tumble and colour evenly, the chaff collects in a pull-out drawer, and Bluetooth lets you drive the roaster and store your profiles from the Gene Café app. It is the successor to the CBR-101.
The Gene Café CBR-301 is the successor to the CBR-101 and roasts up to 300 g of green coffee per batch — a household-sized roast rather than a sample-sized one. The beans turn inside a transparent Pyrex chamber mounted off its axis, so they tumble end over end instead of spinning in one plane, and the air that roasts them is heated indirectly rather than blown across a glowing element. Between the two, the heat reaches every bean at much the same rate, and you can watch the colour change through the glass while it happens.
What it does
- Vortex rotation system — the off-axis movement keeps the beans turning through the whole roast, which is what gives an even colour.
- Indirect hot air — stable, controlled heat, with nothing scorching against a hot surface.
- Bluetooth and the Gene Café app — control the roaster from your phone and store profiles, so a roast you liked can be repeated.
- Built-in chaff collector — the chaff ends up in a drawer that pulls straight out for cleaning.
- Rapid cooling — forced ventilation brings the beans down quickly, so the roast stops where you set it instead of carrying on in the beans' own heat.
- Quiet in a kitchen — you can stand next to it and talk.
