Coffee chemistry from an expert

The following great information is from long-time guest John Hayes.  Just when you think you know everything, somebody with a particular background can show you how much more there is to learn.-----------------------------------------------------------------------------I’m a chemist.  I’m a senior, graduating this spring and moving on to grad school, hopefully, and I can tell you that storing coffee in any kind of plastic container is a bad idea because plastic is porous. While it might not let water in and out to the naked eye, at the molecular level, it does allow a very slow dissipation of atmospheric oxygen in and out.
