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

Frequently Asked Questions
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.
