Thanks for the Good Eats tip Sage. I had already downloaded that episode but not watched it yet. It's informative. I did buy one coffee roasting book too (the only one that seemed half decent).
Vanblah: thanks for the info. I haven't roasted too darkly yet, but that's because I was interrupted both times by the smoke alarm
. Keep me updated on the Aeropress & the coffee it produces, this seems like a good press for the office..
