FAQ

The roasters are optimized for the numbers given. According to our experience, smaller quantities (e.g. 100g on HB-M6 roaster) may provide good results. We highly recommend not to roast larger quantities than the numbers stated on our website and the user manual.

Our HB-M6 model has two versions: for gas M6G an electric M6E. Our HB-L2 roaster is powered by gas. You can use a gas cylinder or may connect it to your facility gas.

Depending on your country, please check with your local authorities if you need additional approval for gas powered roasters. In any case, you should always have a fire extinguisher nearby when roasting coffee.
