RT-200 Home Coffee Roaster: Compact Machine for 200g Batches

If you’ve ever tried roasting coffee at home but found your popcorn popper too uncontrollable or your oven too imprecise, you’re not alone. Many coffee enthusiasts want to roast their own beans to explore origin flavors—but without investing in a commercial drum roaster. The challenge is finding a compact, user-friendly machine that still gives you control over the roast profile.

The RT-200 is a Taiwanese-made, 2.5kg desktop coffee bean roaster designed for home use. It can roast between 80–200g of green coffee per batch, with a maximum output of 800g per hour, making it suitable for single-origin exploration or small-batch experimentation.

Why Home Roasters Consider the RT-200

Home roasting has grown in popularity as more coffee drinkers seek fresher, customizable flavors. Unlike pre-roasted beans—which peak 7–14 days after roasting—home-roasted coffee allows you to stop the roast at your preferred level: light, medium, or dark. The RT-200 fits into this trend by offering a small-batch solution that doesn’t require a dedicated garage or high-voltage setup.

For those experimenting with single-origin beans like Yirgacheffe or Guatemala Antigua, owning a machine like the RT-200 lets you develop a personal roast profile without committing to bulk purchases or large machines. It’s especially appealing to those who have outgrown stovetop methods or air roasters with limited batch flexibility.

How the RT-200 Fits Into Home Roasting Workflows

In a typical home setup, the RT-200 is used to roast small batches that can be brewed the same day or stored short-term for freshness. With a capacity of up to 200g, a single roast might yield enough beans for several days of pour-over, French press, or espresso depending on your consumption rate. The maximum hourly throughput of 800g makes it viable for servicing a small group or rotating through multiple origins throughout the week.

While it lacks the sophisticated airflow controls or digital temperature readouts of premium home roasters, the RT-200 provides a hands-on roasting experience where users can observe first crack, adjust heat timing, and learn the visual and auditory cues of the roast progression.
