That's always been a problem anywhere Brian. coffee roasting in a way is like a finger print. No two are ever going to be the same. People do not have the same setups, voltage, heck even the humidity in the air or a which way the fan is blowing on your roaster can alter it's profile.
Mine does not taste like yours why? ... almost never a simple, oh because you need to tweak xx, it's always something more complicated and the solution is not a 'solution' but a choice of maybe 10 different things, which do you want to do? But that fingerprint, is what also makes it so awesome, when i have some 'secret' up my sleeve and can get flavors, nobody else seems to be able to get, well, there's mom's secret recipe right there!
speaking of, I need to drink some full octane this morning, i need to roast about 8 samples here for another upcoming BIG distro, but just can't find the energy today to get up off my ass and do it! I'll blame it on coming off the flu, I ain't quite right yet
