In specialty coffee roasting, precision is key. Every roast tells a story, and the right tools let you craft that story exactly as you envision it. Enter ArtisanScope — a powerful open-source roasting software — paired perfectly with the Kaleido Sniper Coffee Roaster series. Together, they transform roasting from art into a science of consistency and flavor.

Why Pair ArtisanScope with the Kaleido Sniper?

Kaleido Sniper roasters (M1, M6, and M10 Pro) are built for control: precise airflow, adjustable drum speed, and intuitive touch panels let you fine-tune every moment of the roast. ArtisanScope complements this with detailed real-time data logging and analysis, tracking temperatures, airflow, drum RPMs, and the all-important Rate of Rise (RoR).

This dynamic duo helps you:

Nail repeatable roast profiles

Optimize development times for desired flavors

Troubleshoot heat and airflow mid-roast

Visualize your roast curves with clarity and insight

Getting Started: Integrating ArtisanScope with Kaleido Sniper

To get up and running:

Set up your temperature probes for accurate bean and environmental readings.

Connect ArtisanScope to the Sniper’s control system via tablet or laptop for live data input.

Sync manual controls like drum speed and airflow to capture a full profile.

The Sniper’s allows seamless adjustments, all of which ArtisanScope records for deep analysis.

Decoding Roast Curves: Key Metrics to Watch

ArtisanScope’s graphs reveal critical metrics:

Bean Temperature (BT) – core measure of roast progression

Environmental Temperature (ET) – chamber conditions affecting heat transfer

Rate of Rise (RoR) – how fast temperatures increase, signaling when to tweak heat

Airflow & Drum Speed – key levers for controlling roast development

Understanding these lets you respond proactively, avoiding over-roasting or underdevelopment and dialing in your ideal flavor profile.

Mastering Development Time: The Flavor Shaper

The post-first crack phase, or development time, defines much of your coffee’s final taste — from brightness to body. Kaleido Sniper’s fine heat and airflow controls allow you to tailor this crucial segment with precision. ArtisanScope helps track and refine this phase, supporting consistent, flavorful results.

ArtisanScope Roast Profiles Tailored for Kaleido Sniper
