So, your dry time is as short as mine, and your charge is significantly higher than mine
The quest is a unique little guy ! You also let MET go quite high which is why you have the energy you do - conventional quest wisdom says you should keep met around 500. My MET is measured at the typical location of one of the screw holes in the bean chute - I think that's 10 o'clock. Can you repost your image and show your BT ROR?
My curves are not all over place; the last graph I posted (which is a different bean) is a completely different roasting style on the quest utilizing high heat and high fan. Sorry you can't blow up the image to see the heat/fan settings and other details where you could see this. I posted it as an example, because I'm pretty sure its what Dave was suggesting - shorter maillard while not really increasing the time to first crack. I've explored going away from this to see how a more gentle maillard and dev would taste in the cup. It seems more friendly to naturals because the aggressive maillard period can promote tipping. I don't feel like tipping has anything to do with a short dry - rather, its an aggressive maillard. The reason I posted this thread is because this nicaraguan bean gets really charred and I'm not even going far into dev. It surprises me becaues I'd think that would be an output of aggressive maillard or dev but I've intentionally kept the energy low.
This is getting way off topic but its valuable to quest owners -
I continue to be surprised by quest graphs with only 7-8 degrees of development from first crack (your graph and I've seen one of TomC's profiles before look like this). Conventional wisdom is that a city roast would be 15-20 degrees of development. Your graph shows 7 and you're going into FC at a VERY low energy level. I would look at your profile and think its very underdeveloped. I've asked others this before and still don't really understand it. When I've roasted on the quest and go into FCs at less than 10F ROR, the cracking is barely there. For what its worth, the profiles posted by royal coffee when they're roasting on their probat show the same very very small increase in temp from FCs to roast end. Logically I just don't understand it. I REALLY want to understand it though. Sidenote - I'm referencing sweet maria's temp charts, and also thinking about where I would hit 2nd crack on the quest and dividing the segments up to get city / city + / full city etc
Your suggestion about smelling is a good one - I'm surprised how early (into dev) I do smell the sweet smells, I can try dropping early just to see.
Thanks again for the dialogue !!!
