How Artisan Software Helps You Control Coffee Roast Curves

If you’ve ever tried to roast coffee and ended up with a batch that’s either too light or too dark, you know how crucial timing and temperature control are. Without a reliable way to visualize the roast, it’s hard to repeat a great batch—or fix a bad one. That’s where software like Artisan comes in.

Artisan is a free, open-source application that helps roasters record, visualize, and control roast profiles by tracking temperature over time, offering tools to analyze and refine the roast curve for better coffee flavor outcomes.

What Is Artisan Coffee Roasting Software?

Artisan is software built specifically for coffee roasters who want to take control of their roast profiles. It connects to temperature sensors and PID controllers via your computer to automatically log temperature data and build a detailed roast curve in real time. This visualization allows roasters to monitor the progression of the roast, particularly the relationship between the environment temperature (ET) and the bean temperature (BT), and make informed adjustments throughout the process.

Key Features of Artisan

Artisan is packed with features tailored to both home and professional roasters:

• Free & Open Source: Distributed under the GPLv3 license, Artisan is completely free to use.

• Alarms & Predictions: Offers timed and temperature-based alarms, plus a head-up display that predicts ET and BT development.
• Auto-Marking & Templates: Automatically marks first crack (drop time) and allows setting roast curve templates for reference.
• Stats & Evaluations: Provides configurable roast profile evaluations and statistics.
• Scale Integration: Can connect with an electronic scale to log bean weight automatically.
• Custom Cupping Charts & Flavor Mapping: Users can create custom cupping charts and edit flavor parameter settings with a star-based flavor wheel.

How Artisan Helps Improve Your Roasts

By providing a real-time visual representation of the roast curve, Artisan enables roasters to see exactly how temperature changes affect the coffee at each stage—especially during critical phases like drying, Maillard reaction, and first crack. You can track the Rate of Rise (RoR), which indicates how quickly the bean temperature is changing, giving insight into how the roast is progressing. If the RoR spikes or drops unexpectedly, you can adjust the heat or airflow to bring it back on track.

The ability to log and review past roasts allows for consistency. With roast curve templates, you have a visual guide to aim for with each batch. Integration with scales means you’re also tracking the weight of coffee being roasted—an important factor in batch uniformity. Advanced users can even program the software to manage aspects of the roast machine directly, stabilizing variables that lead to better, more repeatable results.
