Gene Coffee Roaster CBR-301 – Home Coffee Roaster with App Control (300 g)
The Gene Café CBR-301 is a modern home coffee roaster designed for anyone who wants to roast coffee fresh, individually, and with consistent results. It builds on the proven technology of the CBR-101 and adds convenient app control, allowing you to create, save, adjust, and repeat roasting profiles.
Smart Home Roaster with Precise Control
You can operate the roaster directly on the device or via Bluetooth app. Time and temperature can be set with precision and adjusted at any moment during the roast. With temperatures up to approx. 250 °C and a capacity of around 300 g per batch, the CBR-301 offers plenty of flexibility for a wide range of roast levels—from light filter roasts to dark espresso profiles.
The glass roasting chamber provides full visibility of the beans throughout the roast. Thanks to the angled, rotating drum, the beans move evenly for consistent, uniform roasting results. An improved chaff collector keeps your workspace clean and makes maintenance quick and easy.
