Fast Roast Profiles and Air Roasters

A community discussion described a 5–6 minute roast profile as “really fast” in one member’s opinion. Treat this as a subjective assessment rather than a general rule for all machines or coffees. source

Another member noted that 5–6 minute profiles can be standard profile times on air roasters, specifically mentioning Ikawa/KL-style machines. This suggests that profile duration should be interpreted in the context of roaster type: a time that may seem very fast on one platform may be normal on an air roaster. source

Evaluation Reminder

When using very fast profiles, the same discussion advised checking for defects as part of evaluation. In practice, this means not judging the profile by time alone: if the roast works in the cup and does not show defects, the short duration may be acceptable for that roaster and coffee. source
