Letting the roaster warm up for 2 minutes, then roasting them for 8 minutes gives a nice, dark roast. The resulting coffee is smooth, smooth, smooth. One batch is enough for about 14 cups of coffee. Definitely the best coffee I have ever had. And it's fun to watch those little coffee beans jumping around.
Here is a before and after picture:
This is definitely the best frugal experiment to date!
