Not long ago, I received an email where the author had very cynical views about roast profiling. In his story he claimed that roast profiles are overrated, and the general customer does not taste the difference between different profiles. I think this is an excellent and evergreen topic and I know there are many roasters who think the same, but I would like to disagree.o.
WHAT ARE ROAST PROFILES ?
Example of a roast profile using variables like Time, Bean temperature, Exhaust Air temperature and amount of Heat supply
WHY SHOULD YOU USE ROAST PROFILES ?
Are you a Coffee Roaster or a Button Pusher?
Roasters have wide variety of options when adjusting the roast profiles, but the two basic ones are heat output and, if your roaster allows, airflow. With these variables roasters can influence how fast and at what intensity the coffee beans are roasted during the roasting process. This will influence the final flavor.
IS THERE ONE-FITS ALL ROAST PROFILE ?
Kriss Wieser explains how Equator Coffees and Teas is using two very different roasters to profile their coffee. Kriss talks more on profiling in the MEDIUM SIZE ROASTING COMPANY – BEST PRACTICES course module.
HOW MANY ROAST PROFILES SHOULD A ROASTING COMPANY HAVE?
BURSTING THE MYTH
- use a very fast 8 minute roast.
- use a very slow 16 minute profile.
