4. Setup
- Prepare Your Workspace: Choose a well-ventilated area, preferably outdoors or under a strong kitchen exhaust fan, as roasting coffee beans produces smoke. Keep fire alarms in mind.
- Select Heat Source: The roaster is designed for use over a direct heat source, such as a gas stove burner or a portable gas stove. Ensure the heat source is stable and provides consistent heat.
- Gather Green Beans: Measure your desired quantity of green coffee beans. For optimal results, a batch size of approximately 30 grams is recommended.
5. Operating Instructions
Roasting coffee beans with the Nuvo Eco Ceramic Handy Roaster is a hands-on process that allows for precise control over the roast level. Always wear heat-resistant gloves during operation.
- Pre-heat the Roaster: Place the empty ceramic roaster over your chosen heat source on a medium-low setting. Allow it to pre-heat for a few minutes until it is warm.
- Add Green Beans: Carefully pour the measured green coffee beans into the roaster's opening.
- Begin Roasting: Continuously shake and rotate the roaster over the heat source. This constant movement is crucial for even roasting and to prevent scorching.
- Monitor Roast Progression:
- First Crack: After several minutes, you will hear distinct 'popping' sounds, similar to popcorn. This indicates the first crack, where the beans expand and release moisture.
- Second Crack: Continuing to roast will lead to a second, softer series of cracks. This signifies a darker roast.
- Achieve Desired Roast Level: Adjust the heat and continue shaking until the beans reach your preferred roast color and aroma. Common roast levels include: Light, Medium, City, Full City, and Dark.
- Cooling the Beans: Once the desired roast is achieved, immediately remove the beans from the heat source and transfer them to a cooling tray or a metal colander. Agitate the beans to cool them rapidly and stop the roasting process. Rapid cooling is essential to prevent over-roasting.
- Chaff Removal: During roasting and cooling, chaff (the papery skin of the bean) will separate. This can be removed by gently blowing on the cooled beans or using a fan.
6. Maintenance and Care
- Cleaning: Allow the roaster to cool completely before cleaning. The ceramic body is dishwasher safe. For the cowhide grip, wipe with a damp cloth and avoid prolonged exposure to water.
- Storage: Store the roaster in a dry place away from direct sunlight.
- Handle with Care: While durable, ceramic can break if dropped. Handle with care to prevent damage.
7. Troubleshooting
- Uneven Roast: Ensure continuous and consistent shaking/rotation of the roaster over the heat source. Adjust heat intensity as needed.
- Excessive Smoke: Roasting coffee beans naturally produces smoke. Always operate in a well-ventilated area. If smoke is excessive, reduce heat or increase ventilation.
- Beans Not Cracking: Ensure the heat source is adequate and the roaster is sufficiently pre-heated. Increase heat slightly if beans are not cracking after an appropriate amount of time.
- Beans Scorching: If beans are scorching or burning, reduce the heat immediately and increase the intensity of shaking.
