I had read that the process of decaffeinating coffee involves solvents that are bad for you, so I've avoided that. Maybe I should look into that closer because I certainly do enjoy the taste of good coffee.

It's frequently done with liquid CO2. It doesn't leave any residue (and it anyway is not toxic). So you could source beans that use that process.

The roasting process is probably introducing some nice awful compounds into the mix anyway.
