Topic: Caffeine released during roasting? (8 msgs / 119 lines)
1) From: RLutz29934
Any chemists out there? Is any caffeine released during roasting? I usually 
roast our coffee for the week late saturday afternoon. Almost invariably I am 
unable to get to sleep saturday night. I lie awake in bed, my heart pounding 
like I'm really overcaffeinated. Maybe I'm just all giddy about going back to 
work the next day!

I'm no chemist but I can't sleep for several hours after I wok roast in 
the kitchen where the smoke gets quite dense.  When I roast outside 
there is no problem.

According to the data sheet at :http://www.speclab.com/compound/c58082.htmCaffeine sublimes at well below the end temperature of even the lightest roast 
.. . . so it is altogether possible that you might be inhaling some if you 
roast, particularly to the darker roasts (230C and beyond), in an unvented 
room.  Probably not the best way to get the drug, and difficult to titrate your 
dose, but . . . whatever works for you  . . .

RLutz asks:
I can't speak quantitatively, R, but I usually roast 12 batches in a row a
little over 3 hours, and I've never noticed an effect.  Mike McCoffee has
roasted as many as 24 batches at a time and I've never heard him mention it.
I do know that the darker you roast coffee the less caffeine it has in it,
although I was of the opinion that the caffeine was destroyed, not released
into the atmosphere...

Yeah, but I seem to recall MM goes through something like a pound of coffee 
a day.  He must be immune by now 
This is something I  may be able to help with. I can analyze caffeine at 
the lab on my GC/MS.  I will see about rigging an air sampler when 
roasting.  Sounds like fun.

Thanks, John. I'd like to know what you find out. And thank you to everyone 
else for the input. I usually roast about 15-20 seconds into 2nd crack for 
cappuccino, and I LOVE to park my face above the roaster and take in the
