Actually all I was doing was stating a fact of what I am using but if that is promoting I will cease and desist. Kinda useless to belong to a coffee forum without saying what kind of machine one is using as well as what kind of coffee.
As a newbie, what kind of posts should I be making? You're input will be appreciated.
NEARLY everyone took your post that way! As to vac sealing. That on it's own really will not help much, I used to vac seal before freezing but one day I got lazy and used zip top bags while removing all the air I could squeeze out and the preservation was identical to the vac sealed bags as far as I could taste.

I've never done any experimentation to prove, or disprove it, but I have to think that vacuum packing would accelerate the aging process of a coffee bean. Freshly roasted coffee needs to off-gas for a day or two (or more) before it is really at it's peak, and even then it continues to release CO2 from within the bean for a while longer. I believe that this off-gassing is not completely unrelated to the rest of the aging process that occurs in coffee beans, CO2 within the bean may be a part of what we consider "fresh coffee." Storing coffee under vacuum would draw the CO2 (and other compounds) out of the bean. If I ever get around to it, I may try to compare coffee stored in a vacuum vs. coffee stored in a pressurized CO2 environment. Any thoughts?
