Those represent the extremes of my last pan roast. If the middle bean is 50%, most of my roast was beans at 40%.
The leftmost one tasted a little fruity and chocolatey. The middle one tasted baked and toasted and the rightmost one tasted more like burnt toasts, the only one with a frank bitterness.
I think I’m most impressed by the clean cut cross sections you got
My first assumption was that they’d made coffee flavoured cookie dough with different levels of roast (think my mind turned the chopping board in to a countertop)
