Stronghold Unveils S2: The Revolutionary Micro-Batch Roaster Shattering The Limits Of Precision & Power

[Seoul, 03.31.2026] – STRONGHOLD ROBOTICS, INC. (“Stronghold”) is proud to announce the global debut of its S2 coffee roaster. Born from “Project RATEL” and inspired by the world’s most fearless creature, the S2 packs the performance of a production-scale roaster into a nimble, micro-batch frame. This international launch follows a highly successful year in the Korean and Chinese markets, where the S2 proved its commercial viability with over 500 units sold within its first year, establishing it as a field-tested powerhouse for the global coffee community.

Under the product slogan “Roasting without Limits,” the S2 is designed to liberate roasters from the traditional constraints of space and environment. It embodies the vision that wherever you are, that space becomes your roastery. Despite its compact size, the S2 features a significantly upgraded Dual Heat System that delivers a 200% increase in convection heat and 3.3x more radiant intensity compared to existing products. This unparalleled thermal power allows for thorough energy delivery and unlocks the full potential of coffee beans, ensuring vibrant acidity and exceptional flavor clarity for world-championship-level results.

“The S2 represents a new era of ‘Unrestricted Roasting,’ where the ability to craft world-class coffee is no longer dictated by the limits of equipment, but only by the imagination of the user,” said Jason Woo, the CEO at Stronghold. This sentiment is echoed by Ben Put, a 7x Canada Barista Champion and WBC Finalist, who emphasizes that the S2 provides the control of a full production roaster at a fraction of the cost and size, allowing the user’s imagination to be the only limit.

Designed as the ultimate platform for roasting, the S2 offers infinite roles across the industry spectrum with tailored solutions for every community:

• For producers and those at the origin: The S2 allows them to move beyond basic sample roasting to gain a deeper, production-level understanding of coffee quality.
• For competitors and professionals: It introduces surgical precision with 0.1-level heat increments across 100 levels of adjustment, allowing for the most subtle flavor expressions.
• For small cafes: It serves as a daily production roaster for high-end micro-lots with a versatile batch size of 80-300g.
• Even for beginners: The S2 ensures professional results from day one through preloaded programs, an intuitive UI, and AI-driven consistency powered by the signature X-lens infrared sensor.
