After reading the lengthy slashdot discussion of optimal coffee-making techniques (
http://ask.slashdot.org/article.pl?sid=07/05/16/2123222), I took the plunge and bought not only a Chemex coffeemaker (roughly similar to the Mellita, but looks cool and uses special super-filters,
http://www.chemexcoffeemaker.com/), but a coffee roaster.
Roasting your own beans turns out to be trivial (takes 6 minutes, works just like a popcorn popper), and results in awesome, ultra-fresh coffee flavor. The green beans can keep for a couple of years, unlike the roasted beans which start to lose flavor within hours.
The place I bought the roaster (chicanecoffee.com) has a deal where you can buy the roaster together with a variety pack that has a half-pound each of 16 different varieties. I'm nowhere near through it after six months.
Only downside is that darker roasts sometime set off the smoke alarm (no ventilation in my kitchen). The plus side is that everytime I roast, the entire apartment fills with the most amazing smell of roasting coffee...
