Explore how to roast 20 different coffee origins on the Apollo home roaster, with tips on charge weight, roast duration, and flavor outcomes.

Roasting coffee at home doesn’t have to be complicated—but it does require some basic knowledge about charge weight, roast time, and how different beans behave. Whether you're working with delicate Ethiopian coffees or denser beans like Guatemalan Maragogype, understanding how to adjust your approach makes all the difference in the cup.

If you’re using the Apollo home coffee roaster, aim to fill the drum to 60–80% capacity—around 90–120g for optimal airflow and evenness. This also works on most other home and prosumer machines. Even a full 150g load is fine for lighter beans like Yirgacheffe, though larger beans like Guatemalan Elephant may need slight adjustments.

How to Roast on the Apollo: Simple Approach

The Apollo is designed for ease and consistency. Birdman’s advice? Skip complex roast curves. Set a max temperature, control roast time, and let the machine do the work. Home roasters aren’t gas-powered—they use electric heat, which produces a cleaner, more direct roast style. Don't expect an electric machine to replicate the smoky complexity of gas roasting; they're simply different systems.

For high-quality green beans, go with high heat and a short roast—like 9 on the dial for around 10 minutes. This preserves delicate floral and fruity notes. Lower-grade beans benefit from a slower, lower-heat roast (6–7) over 12–14 minutes, which helps reduce off-flavors through gradual development. Most home roasters lean toward premium greens, making fast roasts ideal for vibrant cup profiles.

Controlling Charge Size and Roast Evenness

The Apollo accommodates up to 150g per batch, but 60–80% fill (about 90–120g) gives the best airflow and even roast development. This principle applies across home and commercial machines. While you can technically roast 150g of Yirgacheffe without issue, denser beans like Guatemalan Elephant (23-eye) may roast less evenly at max load, leading to slightly uneven development—though some roasters appreciate the added complexity that comes from minor inconsistencies.

Smaller batches, such as 50g, should be roasted at reduced power—use level 6 to avoid scorching. For most users, batches around 100g roasted in 10–12 minutes strike the best balance between speed, evenness, and flavor clarity.

Using the Apollo’s Interface and Features

Operation is straightforward. Hit the power switch, then press the preheat button. The machine will beep when ready. Load your beans, select a power level, and start roasting. Each number corresponds to a roast time, and the machine stops automatically. Using the factory settings yields uniform color and balanced cup profiles.

Want more customization? Use a separate timer and set the machine to levels 7, 8, or 9. You can stop the roast manually by holding the power button or lifting the lid. Observe bean color and listen for the first and second crack to guide your drop timing. For very small batches under 50g, reduce power to level 6.

Smoke Filtration and Aroma

The Apollo includes an automatic smoke filtration system, which eliminates harsh roasting smoke and replaces it with a sweet, milky aroma—making indoor roasting far more pleasant. This feature isn’t unique to Apollo; other machines like Taiwan’s Little Train roaster offer similar benefits. For home use, built-in smoke filtration is a major advantage.
