I never really looked into the differences in coffee types, that is interesting. I do remember watching a good Good Eats episode once though (I think it was good eats..) where they went in to how a really good decaf coffee actually takes more work than a regular coffee, and is thus pretty expensive.

Good info though.

I had switched from coffee to drinking Earl Grey tea. It has a small amount of caffiene, but a whole lot more nutrients. When I went to that, I felt so much better in so many ways, even physically.

I messed up my tea strainer though, and went back to coffee. I drink 3+ cups a day now, and really need to stop! But can't. The withdrawal symptoms aren't fun at all.
