Frenching ze Roast

I was at the roasting facility today; to conduct a tour for 'Discovery Day'...I had a chance to spend time with Paul in the last few minutes of a batch of BIGGBY French Roast.

Did you know that coffee 'pops' twice in the roaster a lot like popcorn does...you can hear it when I pull in for a close-up at the 'viewing window.' Coffee doubles in size when roasted and explodes out of a cellulose sheath....causing the popping sound. The by-product of this is 'chaf'....much like a light version of a pop corn kernel...

Watch and see coffee in the last few minutes of production... :)
