When I am brewing Decaf Espresso, I frequently smell something like cooked celery. Have any of you experienced this? I know it could be the roaster, but their Reg. Espresso smells wonderful. Some days it makes me almost sick brewing Decaf (yuck).
I don't know much about the differences between Reg. and Decaf other than the physical manifestations and the smell differences I just mentioned. This is just a curiosity of mine, so consider it picking the brains of all you walking espresso encyclopedias. ;-)

that smell you can sense is a mixture of 5 different chemicals which the beans are soaked in to remove the caffein from the beans. Once the soaking is finished the mixture now with caffein is filtered back to its original cocktail of chemicals minus the caffein then used again to do the same.How do i know? I've done some advertising work for a coffee company here in aus and went to the factory where i saw the procedure being done. The company even gave me a copy of the manual the reps use for training when they visit their clients and that also has it in writing.After knowing that would you ever drink decaff again? P.s for legal reasons i can't say the name of this company but i can tell you they are a major coffee company.

Several different decaffeination processes exist, though. Sweet Maria's website has this reference information on decaffeination processes: Decaffeination. Since it sounds like you (Tao) get your coffee from a local roaster, ask him how the beans he buys are decaffeinated and whether he has any different ones you can try.
