My friend Jerry and I and some friends have done a whole set of experiments on various aspects of making coffee, and if I can ever get him off the dime we'll be publishing them here.

So yeah, we Did Some Science. So can you. You can stop reading all these "experts recommend" stories about, e.g. not keeping your beans longer than two weeks, and just carry out a proper experiment on whether you can tell the difference. Who cares if the general population can tell if you can't?

"Doing science" means applying some basic techniques that anyone can learn. Especially the kids.
