L200 Plus
The professional standard in sample roasting
Premium sample roaster for labs and quality-focused professionals, combining advanced sensors, automatic first crack detection, and an enhanced between-batch protocol to deliver consistent and reliable results trusted worldwide.
Why L200 Plus
What makes it different from S200 model
Free software that scales
ROEST Connect is a professional roasting management tool for live monitoring, cupping, profiles, inventory, and data analysis.
Free with every ROEST roaster.
Efficiency that frees your team
1.6kg per hour with minimal labor. Take advantage of automation— spend less time roasting and more time cupping. Essential for roasteries or QC labs processing a lot of samples daily.
First Crack Detection
No manual marking or missed event. No variability. Each coffee reaches its full flavor potential with consistent development time—regardless of who's roasting.
Complete sensor suite
Five temperature sensors (air, bean, inlet, drum, exhaust) deliver the precision and data density needed for confident purchasing decisions, advancing roasting skills or scientific research.
Automated Between-batch protocol
Maintain consistent starting conditions. Switch between batches in one session—each starts identically, delivering the highest roast consistency.

Hear from our customers
ROEST helped the Nordic Approach to increase efficiency and save time:
“I quickly realized how nice it was not to be glued to the roaster the whole day. With the ROEST, I could go back and forth, keeping an eye on my roast while registering and measuring incoming green coffee samples, preparing new batches, packing roasted coffee, or even roasting more samples on a second ROEST!”
- Freja Brunn, lab assistant at Nordic Approach
Nordic Approach recently updated the lab to the new L200 Ultra.
Cafe Imports made a smooth transition to ROEST. The result? Improved workflow and effortless control:
“We were nervous about switching during peak season, but the transition was smooth. Within a week, we were back to full speed. ROEST improved our workflow, roast profiles, and efficiency. I can’t imagine the lab without them now.” - Madeleine Avakian-Salvaggio, EU Sensory & Samples Technician
“ROEST gives us more control with less effort. It’s changed the way we work.”
- Ian Fretheim, Director of Sensory Analysis

The only roasting assistant you need.
ROEST Connect
From inventory to profiles, data analysis to cupping sessions, everything about your coffee is connected in one seamless platform.
Free with all ROEST roasters.
Between-batch protocol
Consistent roasting, batch after batch.
The automated Between-Batch Protocol (BBP) resets your roaster between batches, ensuring consistent thermal conditions for precise, repeatable results every time.
Maintain control over your roast: avoid overheating, replicate your favorite profiles, and achieve the same development batch after batch. Less guesswork, more precision, and full confidence in every sample.
-
BBP resets the roaster’s thermal energy to a target temperature before charging the next batch. Once the desired conditions are reached, the roaster notifies you on-screen and with sound.
Why it matters:
Consistent results: Every batch starts from the same thermal baseline.
Protect your coffee: Avoid overheating as the roaster accumulates heat over multiple batches.
Optimize profiles: Ideal for Power Profiles and Inlet Temperature Profiles for precise replication.
Save time & stress: No need to manually monitor starting conditions or batch order.
In practice:
Roast multiple experimental coffees with confidence that every batch behaves the same.
Maintain consistency throughout long roasting sessions, whether roasting light, dark, small, or large batches.
Focus on flavor and development, not adjusting for the roaster’s changing thermal state.
First crack detection
Smarter workflow, flawless results.
ROEST is the world’s first sample roaster with automatic First Crack Detection. The roaster identifies the exact moment first crack begins, so development time can be precisely controlled for each batch. This ensures every coffee reaches its full flavor potential—consistently, batch after batch, regardless of who’s roasting.
-
A built-in microphone registers the first crack, distinguishing individual beans from other drum noise. The roaster then automatically tracks development time or applies the ratio set in your profile.
Why it matters:
Consistent development: Each batch develops exactly as intended.
No manual marking: Eliminates human error or missed first crack events.
Maximized flavor: Every coffee reaches its full potential with repeatable precision.
In practice:
Every crack is mapped on the roasting curve automatically.
Development time or ratio triggers batch drop without manual input.
Achieve perfectly developed samples, every session.
Built to grow with you
Start here. Upgrade when you're ready.
The L200 Plus delivers professional-grade roasting with comprehensive thermal monitoring, evolving alongside your ambitions.
Unlock advanced sensors, double your throughput, and gain production-scale features as your operation grows—without replacing your roaster.
-
Today: Start with 5 sensors (air, bean, inlet, drum, exhaust) plus First Crack Detection and Between Batch Protocol—everything you need for professional consistency.
When you're ready: Purchase the Ultra upgrade kit to add features:
Dual bean probe system: Add a second bean temperature sensor for enhanced accuracy and redundancy
Pressure sensor: Monitor and control airflow dynamics with precision
Counterflow mode: Double your output from 1.5kg/h to 3kg/h for production roasting
Why it matters:
Upgradeability means you invest once and build over time. This gives you options:
Grow without disruption: Expand capacity when demand justifies it—not before
Spread the investment: Move from artisan-scale to production-scale as revenue grows
No equipment replacement: The roaster you buy today becomes your production workhorse tomorrow
Professional continuity: Scale your output while maintaining profile consistency
Future-proof: New features become available through hardware and firmware upgrades
In practice: Buy the L200 Plus for your micro-roastery or quality control lab. You're processing 10-20 samples daily with professional-grade sensors and First Crack Detection delivering reliable, consistent results. Six months later, sample volume has doubled and you need faster turnaround. Add the Ultra upgrade to unlock Counterflow mode—now you're roasting 15 batches per hour instead of 8. A year in, you're using the pressure sensor to calibrate profiles across multiple machines or optimize airflow dynamics for delicate microlots. Two years later, you're running a high-volume operation processing 3kg per hour on the same roaster—just upgraded.
One roaster. From lab standard to high-volume operation.
