Raters consider the Gene Café Roaster the most powerful home coffee roaster available, and so do we. Both very flexible and remarkably consistent, the Gene Café is capable of roasting very small sample batches, and up to a half pound. Like every home roaster, it takes a little trial and error to figure out the needs of each unique coffee – but once you have found your perfect roast profile, it is remarkably consistent and roasts beans more evenly than any other model. Unlike other home roasters, it is powerful enough to roast numerous batches each day, without lengthy cooling periods (some cooling time is still necessary).
A unique hybrid between fluid bed (air) and drum roasters, it has a patented “Vortex Mixing” method that ensures the most evenly roasted beans. An innovative cooling system brings the temperature of the machine down rapidly, allowing users to roast many batches in a day. Combined with easy operation, this makes it an excellent choice for the home coffee roaster who likes to frequently gift or sell fresh-roasted coffee to friends and neighbors.
Many master roasters also appreciate the effective and easily-cleaned chaff capturing device, and the option to connect a 3” metal dryer hose to vent out a window.
Please Note: Gene Cafe has added a NEW safety feature to this model. It will beep at you a couple of times during the roast and you must press the Blue Button (on/off) to indicate that you are still watching the machine, otherwise it will automatically enter cool mode. There is no way to over-ride this safety feature; it is very important to avoid fire hazards.

Basic Use Instructions
- Start by pressing the release switch to remove the Roasting Chamber. It may be placed into the provided stand so that it stays upright and is easier to fill.
- Pour approx 2-8 ounces of coffee into the chamber, or just fill to the line on the chamber. For high chaff dry processed (natural) coffees, be sure that you do not overfill above the line.
- Plug into a standard polarized 120-volt outlet, but be sure that it is on a circuit unused by other appliances, as it is a very high draw device.
- For most coffees, we recommend setting the temperature control to 440-470F and the timer to 15-22 minutes. Because every coffee is different, some trial and error will be necessary to find the perfect settings, but we have found that these generally tend to work well.
- Hit the Start/Stop button, then watch closely as the roast develops. Like all of our home roasting equipment, the last few minutes of the roast progress very quickly. It is very important to watch carefully, then press the Start/Stop button when the beans reach your desired roast level.
- After the cool cycle is completed, remove the chaff collector on the left side, unscrew the circular cap, lower back, and dump all chaff out. If you see chaff getting stuck between the screens, use a screwdriver to disassemble the collector and remove chaff build-up it before it begins to block exhaust flow.
- You may roast multiple batches each day. However, allowing the machine to cool down for about 40 minutes between batches is recommended.
OPTIONAL: You may attach a 3” metal dryer hose to the exhaust opening and vent it out a window.
PLEASE NOTE: The Gene Café demands close attention, as the roast will progress slowly at first but then very rapidly toward the end.
