Roast rare or experimental coffees with the same control as full-scale production—perfect for limited runs or exclusive offerings.Or start your business with limited offer and scale as your grow.
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.
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.
FAQs
-
They’ve defined professional sample roasting for more than a decade. With the new S200 and L200 Series, we’re closing that chapter and starting a new one — built from the ground up with a redesigned architecture, smarter controls, and hardware ready for future innovation.
Your S100 or L100 Plus remains fully supported with parts, service, and reliability you can count on. However, new firmware and future features will only be available on the S200 and L200 Series.
-
The L100 Ultra was our soft introduction to the new platform. With this launch, we’re aligning everything under a clear, future-ready naming system: S200, L200 Plus, and L200 Ultra. It reflects a new generation of technology and a clean break from the legacy models.
-
The new generation brings a high-resolution touchscreen with dark mode, faster 5 GHz Wi-Fi, redesigned heating and airflow for consistent precision, and a future-ready control board with firmware updates — all built to make roasting smoother, smarter, and faster.

Compact and upgradeable, the S200 is the perfect starting point for professionals who need reliable results and the flexibility for future upgrades.
L200 Plus is a premium professional sample roaster built for labs and quality-focused coffee professionals. It introduces advanced features including a full sensor suite, automated first crack detection, and an enhanced between-batch protocol.
L200 Ultra represents the best of ROEST innovation. Featuring dual bean temperature sensors, drum pressure measurement, counterflow mode, and low-energy roasting, it offers unmatched control and efficiency. The Ultra redefines what's possible in professional sample roasting with faster roast times, optimized heat transfer, and output up to 3 kg/hour. For roasters who demand the best, the L200 Ultra is the ultimate choice.
-
Absolutely. All legacy S100 and L100 models remain fully supported with parts and service. The new generation simply adds the latest technology and future firmware updates.
-
Because airflow and heat dynamics have been upgraded, existing profiles won’t transfer directly — but you can easily recreate and fine-tune them using the expanded profile storage on your new roaster.
-
ROEST Connect is the connected roasting platform that powers every ROEST machine. Track, analyze, and share your roasts, manage your library, and collaborate with the global ROEST community — all in one place.
-
It’s included, completely free, with every ROEST roaster.
It is one connected platform used for our sample and production roasters.
-
You can take advantage of our trade-in program through your ROEST partner or directly with us. We’ll handle the process and ensure your unit is refurbished and resold responsibly.
-
All ROEST roasters include a one-year warranty, free software updates, and ongoing customer support from our global team.
-
For nearly a decade, every ROEST machine has been designed to evolve — with firmware updates, hardware upgrades, and continuous improvements. That promise hasn’t changed.
But after ten years of innovation, we’ve reached the limits of the original hardware platform. The new generation uses a completely redesigned control board, heating system, and internal architecture that enable faster performance, smarter connectivity, and future software updates — features that simply aren’t compatible with the previous design.
Rather than a retrofit, this is a rebuild from the ground up — made to carry ROEST forward for the next decade and beyond.
Your S100 and L100 Plus remain trusted, professional tools, and we’ll continue to support them. The S200 and L200 Series build on that same promise of longevity, now with a platform ready for the future.
