10 Best Coffee Roaster Machine 2025 in the United States

The Fresh Roast SR540 is a manual coffee roaster designed for home users who want control over small batch roasting. It handles about 3 to 4 ounces of green beans at a time, which is sufficient for personal use but might be limiting for larger quantities. It uses a dry heat roasting method and provides hands-on control, allowing you to tweak the roast to your taste if you enjoy experimenting. The included glass extension tube aids in airflow and smoke management during roasting.

The bundle includes useful extras such as a digital pour-over scale for accurately measuring beans, two sample trays, a chaff brush for cleaning, and a 2-pound supply of green beans to get started. Its compact size (about 8.5" x 8.5" x 19.5") makes it portable and suitable for kitchen counters without occupying much space.

This manual roaster requires you to monitor the roasting process yourself, which may not be ideal for those seeking a fully automatic system. It operates on 1250 watts and the digital scale requires 2 AAA batteries. Manual roasters like this typically produce some roasting noise and need regular cleaning, especially of the chaff. The Fresh Roast SR540 bundle is a solid choice for coffee enthusiasts who want a hands-on roasting experience in small batches with helpful starter accessories, providing good value and control for home roasting beginners and hobbyists.

The KALDI FORTIS PLUS is a home coffee gas roaster designed to handle up to 600 grams of green coffee beans per batch, making it suitable for enthusiasts who want to roast moderate amounts at once. It uses a direct flame drum roasting method, giving users good control over the roasting process and allowing for a hands-on experience similar to professional setups.

The roaster includes a cyclone combined with a natural exhaust system to improve airflow and smoke management, helping keep the roasting environment cleaner. Controls are manual with a touch interface, which offers precise adjustment during roasting but might require some learning. Running on gas and weighing about 84 pounds, it is not very portable and needs a proper setup area, making it best for dedicated home spaces rather than casual or travel use.

Cleaning may be somewhat involved due to the integrated cyclone and exhaust parts, but the included cooler helps quickly bring roasted beans to the right temperature. The gas burner and metal drum construction typically produce noticeable roasting sounds common to similar equipment. This model suits home coffee hobbyists who value quality roasting and are comfortable with manual controls and a less compact design, while casual users or those seeking a quieter, more portable, or electric option might find it less convenient.

The Kaldi Fortis Coffee Roaster is designed for coffee enthusiasts who appreciate precision and control in their roasting process. It offers a decent 600g batch capacity, making it suitable for both personal use and small-scale roasting. The semi-convective roasting method ensures even heat distribution, which is essential for achieving a consistent roast. However, it requires a gas burner, which adds an extra element to manage compared to electric roasters, potentially making it less convenient for some users.

The dual data logger thermometer is a standout feature, allowing users to closely monitor and adjust temperature settings, providing greater control over the roasting process. This is particularly beneficial for those who are meticulous about their coffee profiles. In terms of size, the dimensions (20.87 x 12.6 x 17.32 inches) suggest that it is relatively compact for a coffee roaster of its capacity, making it a viable option for home kitchens. Its weight of 1.32 pounds also implies ease of portability.

Available since 2016 and still not discontinued, the Kaldi Fortis appears to be a durable option with positive customer feedback, reflected in its high ratings. Ideal for dedicated coffee roasters who are willing to manage a gas burner and seek precise control over their coffee roasting.
