S200 & L200 Series: The New Generation of ROEST Sample Roasters

Introducing the S200, L200 Plus, and L200 Ultra

For over 10 years, ROEST has been guided by curiosity, coffee, and community feedback. Your input has shaped every machine we build. Today, we are proud to introduce the new generation of ROEST sample roasters. The S200, L200 Plus, and L200 Ultra are designed to provide better control, more accurate data, and a reliable roasting experience for every batch.

The Evolution of ROEST Machines

The S100 and L100 Plus have been trusted by roasters in over 100 countries. Earlier this year, we introduced the L100 Ultra in a soft launch. Now, it has been updated and renamed as the L200 Ultra, joining the S200 and L200 Plus to form the New Generation Series.

The previous design reached its limits. The new generation is not just an upgrade. It is a rebuilt platform with improved usability, precision, and technology, while keeping ROEST’s core values intact: reliability, long-term support, and upgradeable features.
