L200 Ultra
Redefining professional sample roasting
The L200 Ultra represents the best of ROEST innovation, with faster roast times, optimized heat transfer, up to 3 kg/h output, and unmatched performance for roasters who demand the best.
Why L200 Ultra
What makes it different from other models
Speed when you need it
15 batches or 3kg per hour. For high-volume labs, doubling throughput means cutting labor costs in half.
Energy efficiency option
Achieve similar roast development at lower power consumption. Roast profiles that are faster, more energy-efficient, and gentler on the beans.
Multi-roaster calibration
The pressure sensor allows for greater precision in controlling airflow and makes calibrating settings across different machines easy.
Lower temperatures, gentler profiles
Counterflow's efficient heat transfer lets you roast at lower temps. Avoid scorching on delicate coffees. Bring out subtle flavors in expensive microlots.
Unprecedented control
Ultra features full sensor suite with a new dual bean temp for accuracy across batch sizes. Unprecedented control over roast environment and airflow dynamics.

You can take over at any time, with precise control over power, airflow, and RPM. Use the trier for visual checks during roasting.
-
Reset the thermal energy of the machine between batches for perfect profile replication.
-
All-new touchscreen interface with roasting info at a glance, more intuitive controls and easier access to the settings and information you need.
Sleek new interface offers more customization to match the roaster’s design aesthetic, with dark or light modes.
-
Reversible drum allows option for direct airflow to the heart of the beans for ultra-efficient gentler heat transfer.
-
Redesigned to operate at higher temperatures for longer, and to better withstand power outages.
-
Immediately start roasting the next batch while the previous batch cools.
-
ROEST Connect is more than advanced roasting software—it’s your roasting assistant. Create profiles, follow your roasts live, manage inventory and cuppings, and analyze every detail of your roasting history. Seamless for beginners and powerful for pros, ROEST Connect streamlines workflow and sharpens results at every stage. Free with your ROEST roasters.
-
All new WiFi module for easy connectivity and faster, more stable networking.
-
Start with S200 model and upgrade to the higher model when you are ready. No need to go through complicated hardware installment. Simply purchase feature upgrade and enjoy!
-
Roast batch after batch without a worry.The roaster collects up to 2kg of chaff in the built-in drawer. On the touch screen you will get notified when it is needed to be emptied.

Features
Sensors
-
Monitor temperature of the air inside the drum.
-
Fast, responsive BT probe for manual roasting. Dual sensor in the L200 Ultra.
Single BT probe in L200 Plus and S200 model.
-
Profiles adapt to ambient changes or power supply fluctuations.
-
Get perfect consistency by monitoring the heat in the roaster itself.
-
Monitor outgoing air to track heat absorption by the beans.
-
This sensor is specific to the L200 Ultra model and allows for greater precision in controlling airflow and calibrating settings across different machines.
-
Automatically mark first crack and end the roast based on development time. Record each crack in your roast logs, for a fuller understanding of how beans behave in the roaster.
For roasters who demand the best
Scott Rao recognizes the value of Ultra for busy operations, particularly in terms of heat-transfer efficiency and faster roast times.
"Counterflow mode doubles the heat-transfer efficiency of the Ultra. That gives roasters the option to roast safely in as little as 5 minutes per batch or to roast using much lower temperatures than before. Roasters can now roast faster while producing softer-tasting coffee."
- Scott Rao, Coffee consultant and author
Aviary Coffee Roastery increased batches per hour and reliability in the cup across different batch sizes
“I switched to the ROEST Ultra because it gives me precise, reliable data, even on tiny 50g sample roasts. The built-in pressure sensor makes it easy to control airflow and calibrate across machines, so I get consistent results every time. It’s efficient too—I can roast more samples per hour without losing quality. For anyone who needs repeatable, dependable results, it’s a real difference.”
- Christopher Feran, Aviary Coffee Roastery
Roast faster, gentler, smarter.
Counterflow mode
Counterflow mode redefines roasting efficiency by reversing the drum’s airflow for direct, high-impact heat transfer.
Roast double the beans in nearly half the time, or lower your temperatures for smoother development and cleaner flavor. Save energy, protect your coffee from scorching, and match the performance of large-scale production roasters
-
Standard mode: Drum rotates so beans tumble away from airflow inlet. Indirect heat transfer—similar to S200/L200 Plus roasting style.
Counterflow mode: Drum reverses direction. Beans tumble directly into airflow path—just like our P3000 production roaster.
Why it matters:
Counterflow enables radically more efficient heat transfer from air to beans. This gives you options:
Roast faster: 4-minute 200 g batches vs 7+ minutes standard
Roast cooler: Achieve same development at lower temperatures
Roast gentler: Efficient heat transfer reduces risk of scorching
Use less energy: Lower temps = lower power consumption
Model production: Airflow dynamics match large-format roasters
In practice:
Test the same experimental coffee at multiple speeds. Roast high-moisture beans gently at low temps. Process 15 samples/hour when volume demands it. Or run in standard mode when you need L200 Plus-style profiles.Complete flexibility. One roaster.
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.
