Hello!

This profile is well balanced, but this coffee may prefer a more gentle heat application into mid phase to keep your finish temp a little lower at the end of the roast and bring back some aromatics.

A finish temp of 389F is likely dulling some of the aromatics. If first crack is starting at 365F on your machine, the +24F finish temp could be the culprit.

Try moving your gas adjusment made at green > yellow back by 1:00 for more gentle heat out of dry phase. Same thing with your gas before first crack. At around 350F you may want to be at around 0.4 kPa to slow down into development.

Aim for a finish temperature of 373F to 375F with 1:00 - 1:30 in development and see if you get your aromatics back. If your aromatics come back, but the cup is tart or vegetal, elongate development by 15 seconds to see if it unlocks sweetness.

If it helps to think of this in phases and times, I have an example below.

Current profile:

8:56

50 / 32 / 18

4:28 / 2:52 / 1:36

Suggested profile:

9:20

48 / 38 / 14

4:45 / 3:20 / 1:15

Happy roasting!

Hi Bryant!

Thank you so much for your helpful and insightful feedback.

i've actually Applied the roast profile you suggested, and now am waiting for resting period time to finish before cupping the coffee.

Thanks again :)
