Home Roaster Technique

A quick reference for using my roommate’s home coffee roaster.

Pre-warm to 200 ºF

‘Start’ button

‘P5’ for max heat

Press ‘B’ button to check temp

Add in 250 g green beans

Set stopwatch timer

‘P5’ for max heat

Beans brown (~8 min)

Reduce heat to 50% (P3)

First Crack

Look for steam

Listen for first crack (~9.5 min)

Second Crack

Let beans roast until just before second crack (~11.5 min)

Hit ‘Cool’ button

Open roaster

Blow on cage to accelerate cooling


Let beans breath in brown paper bag 24 hours
