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!

<Snip> 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: <Snip> 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... -- Rick homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast
Chemist here. Sometime around 11:58 10/26/02, Rick Farris typed: <Snip> Yeah, but I seem to recall MM goes through something like a pound of coffee a day. He must be immune by now <Snip> 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. -- John Nanci AlChemist at large Roasting and Blending by Gestalt homeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast

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 aroma! Bob Lutz
