How Artisan Software Helps Roasters Control Coffee Profiles

When you’re trying to roast coffee consistently—whether you’re dialing in a light Yirgacheffe or developing a dark Sumatra profile—knowing exactly what’s happening to your beans inside the drum is everything. But without the right tools, you’re guessing. That’s where Artisan comes in.

Artisan is free software that helps specialty coffee roasters record, visualize, and control roast profiles by connecting to thermocouples and PID controllers. It captures real-time temperature data and turns it into actionable roast curves, enabling you to make informed decisions that shape flavor development.

What Is Artisan and Why Use It?

Artisan is open-source software designed specifically for coffee roasting. It allows roasters to log temperature data from a thermocouple (measuring bean or environmental temperature), visualize roast curves in real-time, and control aspects of the roast via a connected PID controller. Whether you're a home roaster or a small-batch commercial roaster, Artisan provides the tools to track and refine your roast profiles with precision.

• Profile statistics based on configurable roast phases
• Background reference profiles
• User-defined cupping profiles and graphs
• HTML and CSV export options
• Omega HH506 and K202-specific CSV import
• PID duty cycle control
• Pre-designed curve tool (profile designer)
• Wheel graph and mathematical plot editors
• Multiple language localizations (German, French, Spanish, Swedish, Italian)
• Multi-core CPU optimization
• Template and background playback features
• Programmable alarms
• Automatic CHARGE (drop-in) and DROP (end of roast) event detection

How Artisan Captures and Uses Roast Data

By linking a thermocouple (measuring either bean or environmental temp) and optionally a PID controller to your roaster, Artisan collects temperature data throughout the roast. It then displays this data as curves showing the rise of bean temp (BT) and environmental temp (ET), along with their rate-of-rise (RoR)—a critical metric for controlling the Maillard reaction and development time. You can manually log key roast phases (like First Crack start/end), set custom events, and even trigger alarms for CHARGE and DROP moments. The software predicts future temperature trends using a thermal head-up display, helping you make real-time adjustments. All roast data can be analyzed post-roast, with statistics broken down by user-defined phases, and exported as detailed HTML or CSV reports for sharing or further analysis.

Version History Highlight

In version 0.5.6 (released 2012-11-13), Artisan fixed bugs related to the CENTER 301 thermometer and added support for the Voltcraft K201.

Frequently Asked Questions

What is the Artisan coffee roasting software?

Artisan is free, open-source software that enables coffee roasters to record, visualize, and control roast profiles by connecting to temperature sensors (thermocouples) and PID controllers. It tracks bean and environmental temperatures, rate-of-rise, and other metrics to help optimize roast curves.

What devices does Artisan work with?

Artisan supports a wide range of thermocouples and PID controllers, including Fuji PXR/PXG 4 & 5, Delta DTA, various Omega models (like HH506RA, HH806AU), CENTER series, VOLTCRAFT K202/K204, EXTECH 421509, Arduino TC4, TE VA18B, Amprobe TMD-56, and even virtual or manual input devices.

Can Artisan help improve my roast consistency?

Yes. By providing real-time temperature tracking, rate-of-rise curves, and predictive tools, Artisan allows roasters to make informed adjustments during the roast and analyze past roasts to replicate successful profiles, improving consistency over time.

Does Artisan support exporting roast data?

Yes. Roast data can be exported in both HTML and CSV formats. Specific models like Omega HH506 and K202 also allow for individual CSV imports. This helps with record-keeping, analysis, and sharing roast profiles.

Is Artisan suitable for home roasters?

Absolutely. While it’s used by professionals, Artisan is free and works with many entry-level thermocouples and roasting machines, making it a powerful tool for home roasters who want to take control of their roast profiles.
