A sample coffee roaster is a small-capacity machine — typically 100g to 600g per batch — designed for green coffee evaluation, quality control, and roast profile development. Whether you are a coffee importer grading incoming lots, a green bean trader cupping samples, or a specialty roaster dialing in a new origin, a sample roaster is the professional’s essential tool.
Who Needs a Sample Coffee Roaster?
- Green coffee buyers & importers — cup and grade lots before purchase commitments
- Coffee labs & R&D teams — develop roast profiles before scaling to production
- Competition roasters — fine-tune single-origin batches for championships
- Specialty cafés — experiment with microlots without waste
Yoshan Sample Coffee Roasters: 100g, 500g & 600g
100g Sample Roaster (SD-100G)
The SD-100G drum sample roaster is built for cupping labs and trading companies. Its small batch size minimizes green coffee waste while delivering a roast curve that mirrors your full production machine.
500g Electric Sample Roaster (EC-500G)
The EC-500G is our most popular electric sample roaster. Full electric heating means no gas permit required — ideal for offices, labs, and indoor facilities across Europe and North America. PID temperature control ensures batch-to-batch consistency.
600g Configuration
Yoshan can configure 600g sample drums on request. Contact us for custom capacity options.
Key Specs to Compare
| Spec | What to Look For |
|---|---|
| Batch size | 100g (cupping), 500g–600g (development) |
| Heat source | Electric (indoor-friendly) or gas |
| Temperature control | PID or programmable profile logging |
| Certifications | CE, ISO 9001 |
Production Throughput of a 500g Sample Roaster
With a 12–15 minute roast cycle plus 5 minutes cooling, a 500g sample roaster completes 3–4 batches per hour — up to 25 batches per day.
Adjustable Control: Temperature, Airflow and Drum Speed
Serious evaluation work needs an adjustable sample coffee roaster — fixed-profile machines cannot replicate your production curve. Yoshan sample roasters give you independent adjustment of heating power (PID-controlled on the EC-500G), airflow damper and drum speed, so a 100g cupping roast can be matched to the profile of your 6 kg or 12 kg production machine. Data logging via USB lets you overlay sample curves against production curves in Artisan — see our Artisan connection guide.
Green Coffee Sample Roasters for Buying Decisions
The core job of a green coffee sample roaster is protecting your purchasing budget. Importers and green buyers roast 100–150g of each candidate lot to a standardized profile, cup them side by side, and only then commit to full bags or containers. A consistent sample roaster removes the machine as a variable, so what you taste is the coffee — not roast noise. This is why trading companies typically choose the drum-type SD-100G: same drum physics as a production machine, minimal green waste per evaluation.
Which Sample Roaster Is Best for a Coffee Lab?
For most cupping labs and QC departments, the EC-500G electric sample roaster is the best choice: no gas permit, PID repeatability, and enough batch size (up to 500g) to feed a full sensory panel from one roast. Choose the 100g drum machine instead when your lab must mirror drum-roaster physics exactly, or when green sample quantities are very limited. Larger labs often run both — 100g for screening, 500g for profile development.

Frequently Asked Questions
Are Yoshan sample roasters adjustable?
Yes — heating power, airflow and drum speed are all adjustable, and the EC-500G adds PID temperature control with USB data logging for Artisan.
How much does a sample coffee roaster cost?
Professional sample roasters typically range from $300 to $1,500 depending on batch size and control level. Request a factory-direct quote with courier shipping to your door.
What is the difference between a 100g and 500g sample roaster?
The 100g is purpose-built for cupping. The 500g produces enough roasted coffee for a full sensory panel or competition preparation run.
Can I use a 500g sample roaster for small commercial production?
A 500g roaster can produce roughly 10–15 kg of roasted coffee per day. For retail or wholesale supply, we recommend a 1kg or 3kg machine.
Do Yoshan sample roasters carry CE certification?
Yes. All Yoshan machines carry CE certification and SGS testing reports. We ship to buyers across the EU, UK, USA, Australia, and the Middle East.
