How to Roast 20 Coffee Beans with the ICOFFEE N901CR Home Roaster

If you’ve just unboxed your first home coffee roaster and wonder whether you can actually roast great-tasting beans without diving into complex curves and professional techniques, here’s the honest truth: yes—you can. The key isn’t chasing perfect curves, but nailing a few practical variables. This guide walks through how to get quality roasts using the ICOFFEE N901CR, based on real results from 20 different green coffee origins.

The ICOFFEE N901CR achieves excellent roasting results with a simple approach: set a max temperature and control roast time. For high-quality beans, try 9 out of 10 power for 10 minutes. For lower-grade beans, lower the heat and extend roast time. Most users roast around 10–12 minutes for about 100g, avoiding comparisons to gas roasters due to fundamental heating differences.

Quick Answer: What’s the Best Way to Roast on the ICOFFEE N901CR?

Set your max temperature, then control roast time. For premium green beans, use high heat (9/10) for a short roast (around 10 minutes). For lower-grade beans, go lower heat and longer roast. The default factory settings give balanced results. Use a timer if dialling in more nuanced profiles. Roast 100g beans for 10–12 minutes at 7–9 power for best results.

How the ICOFFEE N901CR Works: Setup & Operation

The ICOFFEE N901CR is designed for simplicity. Before roasting, press the preheat button until it stops and beeps. Then load your green beans, select your power level, and start. Each number on the control corresponds to a roast duration. The machine stops automatically when done. Factory settings yield evenly roasted beans with balanced flavour.

For more customised flavour profiles, use a stopwatch. Set the roaster to power levels 7, 8, or 9, and monitor bean colour and the first crack. You can pause the roast by holding the power button or open the lid to drop the beans early. Reduce power to around 6 if roasting smaller batches, like 50g.

Typical roast times: 10–12 minutes for ~100g beans at power 7–9.
Smaller batch adjustment: 50g beans should use power 6.

Roasting Different Coffee Bean Types: What Worked Best

The N901CR was tested on a wide range of 20 different green coffee origins. While appearance varies, taste is the real test—and some of the best cups came from beans that didn’t look perfect. Below is a list of the beans roasted, with no particular ranking, just a visual record. Flavour outcomes varied, proving that roast quality often outweighs bean aesthetics.

• French Guadeloupe Vanibel Plantation (Blue Butterfly)
• Madagascar
• Mandheling Peaberry
• Mexico Cassandra
• Uganda Organic
• New Caledonia Kouancou Plantation (Rayleigh)
• Yirgacheffe
• India Washed Robusta (Emperor)
• Vietnam Arabica
• Australia Hilltop (Semi-washed)
• Panama El Hamon Estate
• Peru (Organic)
• Indonesia Kopi Luwak (Civet Coffee)
• Bolivia Typica
• Guatemala 23-Size Elephant Bean
• Colombia Hy Blue
• Costa Rica Wolf Estate Honey Process
• Guatemala Antigua
• Hawaii Kona Peaberry
• Kenya AA

Note: Roast appearance doesn’t always predict cup quality. Some beans that looked less appealing tasted better, and vice versa.

Batch Size & Uniformity: Why It Matters Even at Home

The ICOFFEE N901CR has a maximum batch size of 150g, but the recommended load is 60%–80% of capacity (about 90–120g). This ensures even airflow and heat distribution. Roasting large or dense beans—like Guatemala Elephant Beans—at full capacity can lead to uneven roast development. While roast degree affects flavour, evenness is especially crucial for beginners aiming for balanced cups. Even minor roast inconsistencies can be tasted, though some variance may add complexity.

Smoke Management: The Smart Design Advantage

The ICOFFEE N901CR includes an automatic smoke filtration system. This makes indoor roasting far more pleasant—no harsh smoke, just a light sweet-milk aroma in the room. Similar systems are found on other home roasters, such as models from Taiwan, which also produce a notably clean roast environment. If you’re roasting indoors, this feature alone is a major benefit.

Frequently Asked Questions

What’s the best power setting for high-quality beans on the ICOFFEE N901CR?

For high-quality green beans, use a high power setting—around 9 out of 10—and roast for about 10 minutes. This approach highlights brighter, cleaner flavours and avoids over-developing the roast.

Can I roast small batches like 50g on the N901CR?

Yes, but reduce the power to around 6. Lower heat prevents scorching and allows for more even development with smaller quantities.

How long should I roast for a balanced flavour?

Most users achieve balanced results with roast durations of 10–12 minutes. For 100g batches, staying within that time range at moderate to high power (7–9) gives consistent outcomes.

Does the N901CR produce a lot of smoke?

No. The roaster features an automatic smoke filtration system that greatly reduces smoke, making indoor roasting much more manageable and pleasant compared to unfiltered machines.

Is gas roasting better than electric like the N901CR?

They’re different, not necessarily better or worse. Gas and electric roasters use distinct heating methods, and many roasters report that electric roasts don’t achieve the same deep Maillard tones as gas. The N901CR offers a clean, user-friendly electric roast profile ideal for home use.

What’s the ideal batch size for even roasting?

Load the roaster to 60%–80% capacity (approximately 90–120g). Going beyond 150g can lead to uneven heat distribution, especially with larger or denser beans like Elephant Beans.
