I'm involved in a little "roast off" competition that got started on a coffee forum I belong to:

http://www.opencoffee.net/news.php

I think there is at one least pro roaster besides myself that is participating. It's a great way to try other's coffee/espresso roasts. My entry was the "Open Blend" a dark espresso roast. I have been working with a local espresso bar to develop a blend for milk based drinks only. You know, the 20 oz latte crowd. Anyway, this "roast-off" is a great way for me to get feedback on new blends from a group of coffee educated folks.

What did the group think about it? Go check it out for yo'self.
