Enhanced Flavor Clarity and Coffee Quality
Roastronix is thrilled to unveil the Stronghold S8X, making its highly anticipated US debut at the Specialty Coffee Expo in Houston on April 25. This state-of-the-art electric roaster is designed to meet the needs of space-conscious cafes while offering unmatched roasting precision. With a compact footprint of just 3 square feet and a 4.5-kilo capacity, the S8X is redefining what’s possible for cafe roasting.
The Stronghold S8X is engineered to bring out the best in every coffee, ensuring greater depth of flavor, enhanced clarity, and a consistently high-quality roast. By leveraging the precise control of halogen quartz elements, this roaster allows baristas and roasters to develop nuanced flavor profiles that highlight the unique characteristics of each coffee origin.
Radiant heat application ensures that heat penetrates evenly into the bean, reducing the risk of scorching or underdevelopment. The advanced airflow system provides superior thermal stability, preserving delicate aromatics while balancing acidity and sweetness. Whether you’re working with bright, fruit-forward Ethiopians or rich, chocolatey South American coffees, the S8X gives roasters the ability to fine-tune every aspect of the roast for unparalleled results.
Additionally, the infrared X-lens technology precisely monitors bean surface temperature in real-time, ensuring that every roast is consistent and repeatable. The ability to accurately reproduce roast profiles means that customers will enjoy the same exceptional coffee experience every time they visit your cafe.

Designed for Every Type of Roaster
The S8X is built for versatility. Cafe owners can lower their Cost of Goods Sold (COGS) by roasting in-house instead of purchasing roasted coffee from external suppliers. For larger roasteries, the S8X provides an ideal platform for small-batch experimentation and exclusive releases.
New to roasting? The S8X’s automated profiles allow cafes to step into roasting with confidence. As baristas and managers gain experience, the real-time manual control offers an opportunity to fine-tune every variable. With adjustable drum temperature, speed, airflow, and halogen heat application, operators can manipulate their roast with unprecedented precision.
The Power of Halogen and Infrared Precision
Stronghold’s proprietary technology sets the S8X apart. It employs halogen quartz elements for radiant heat application, delivering consistent, controllable heat directly to the beans. This method ensures even inner-bean development, providing greater clarity of flavor and balanced roasts.
Additionally, the infrared X-lens system monitors bean surface temperature in real time, allowing the roaster to adjust parameters mid-roast. With five temperature sensors throughout the machine, data accuracy is ensured, contributing to repeatable, predictable results.

Improved Airflow and User-Centric Design
The S8X’s upgraded airflow system ensures consistent heat distribution, further enhancing even bean development. Operators can now adjust blower speed, optimizing roast dynamics for different coffee varieties and roast levels. The cooling tray has also been upgraded with a built-in LED-powered light, making post-roast quality control easier than ever.
The Electric Roaster That Stands Out
While electric roasters are gaining popularity, the Stronghold S8X stands out from competitors. Unlike other electric roasters’ more automated, hands-off approach, the S8X offers roasters complete control over the process. With real-time manipulation of drum temperature, speed, and airflow, the S8X caters to both newcomers and experienced roasters who seek creative freedom.
In terms of precision, the S8X’s five temperature sensors provide deeper insights into the roast, ensuring unparalleled consistency. Once a successful profile is saved, it can be replicated with pinpoint accuracy—a feature especially beneficial for multi-location cafes maintaining brand consistency.
Flexible Capacity for Any Operation
Whether you’re a bustling roastery looking to profile small, exclusive lots or a cafe roasting daily for retail and service, the S8X’s batch capacity of 1.5 to 4.5 kilos offers flexibility. Smaller batches allow meticulous attention to rare, expensive coffees, while larger batches support efficient in-house production.
A Greener, Smarter Solution
The Stronghold S8X is powered entirely by electricity and produces zero emissions when used alongside the JT smoke filter. By eliminating the need for gas, it helps reduce a cafe’s carbon footprint, offering a sustainable solution for businesses that prioritize environmental responsibility. Whether you’re aiming to decarbonize your operations or simply seeking a cleaner roasting experience, the S8X makes sustainability seamless.
Experience the Future of Roasting
The Stronghold S8X represents a new era of coffee roasting—one that prioritizes sustainability, consistency, and control. With its cutting-edge halogen heat technology, real-time manipulation capabilities, and data-driven precision, the S8X makes exceptional roasting accessible to cafes of all sizes.
