Gene Café coffee roasters
Gene Café coffee roasters
With a Gene Café roaster you roast your own coffee at home. You set the temperature and roast time yourself and watch the beans change colour through the glass drum. We sell the CBR-101 with manual controls, also as a starter pack, and the CBR-301 with Bluetooth and an app, plus spare parts to keep your roaster going.

Gene Café CBR-101 vs CBR-301: which roaster is right for you?
Both roasters share the same technical basis: hot air, a rotating glass drum, and the same capacity and roast time. The difference lies in how you control the roast.
Gene Café CBR-101
You set temperature and time by hand on the control panel and follow the roast by eye and ear. A good choice if you are starting out, or if you like to roast by feel.
Gene Café CBR-301
The CBR-301 adds Bluetooth. With the smartphone app you can follow the roast in real time and save roast profiles, so a result you like is easier to repeat. It is the logical step up if you want to experiment with profiles.
How the Gene Café roasts
Hot air swirls around the beans in a vortex while the drum turns, so they roast evenly. The drum is made of heat-resistant Pyrex glass, which lets you see the colour change as the roast goes on. After roasting, the machine starts a cooling phase by itself.
The beans keep developing a little while they cool. Bear this in mind and stop the roast slightly before the colour you are aiming for.

Getting started with home roasting
You roast green, unroasted beans; you will find them under unroasted coffee beans. A few tips for your first batches:
- Start with a smaller batch and write down time and temperature every time, so you can repeat what works.
- Roast near an open window or under an extractor hood: roasting produces smoke and chaff.
- Let freshly roasted beans rest for a day or two before brewing, so the gases can escape.
- Grind just before brewing; see our coffee grinders.
