Bluetooth App Control
- Connect to the free Gene Cafe app on iOS or Android to control roasts, build custom profiles, and save your favourites for perfect repeatability







The Gene Cafe CBR-301 is the next generation of one of the most beloved home coffee roasters ever made. It keeps the patented vortex twisting, off-axis chamber rotation that made the original famous for remarkably even roasts, and adds Bluetooth connectivity, app-based roast profiling, and variable fan and drum speed for a level of control home roasters have never had at this price.
With a 300 gram capacity, the CBR-301 roasts enough for a full week of coffee for most households in a single batch. Load green beans into the Pyrex glass chamber, set your time and temperature on the simple two-knob interface, or build a complete roast profile in the Gene Cafe app for iOS and Android. Watch the roast develop through the clear chamber, and when the cycle finishes the roaster automatically switches to cooling so your beans never overdevelop. The removable chaff drawer makes cleanup quick.
Whether you are roasting your very first batch or you have years of home roasting behind you, the CBR-301 makes consistent, repeatable results simple. Save your best profiles in the app, repeat them batch after batch, and enjoy coffee roasted exactly the way you like it, fresher than anything you can buy off a shelf.
