This is a great sample roaster. It's a single barrel, gas-powered sampler. It's 3 years old, in great condition, and very well maintained. It includes: flexible exhaust hose, brushes, filler tube, lubricant, and sampler spoon. Here's the description from Probat: "Probat BRZ Series Sample Coffee Roasters allow you to test optimal roasting parameters on a small scale
and transfer them to full-scale production. Experiment with new beans and specialized blends to determine
your ideal roasting parameters. Our small-scale roasters allow for complete roasting flexibility." Please let me know if you have any questions.
