I tend to agree with that sentiment. I've found that the African beans, in general, are my favorites. Beans I've had from Central and South America have been okay, but not outstanding to me. The only exception has been Colombian beans. But even then, it depends on the season and quite possibly the farms too, if the Colombian beans meet my threshold for being outstanding. Some batches have met that standard and many more have not. So with the Colombian beans, its usually a crap shoot if I'm going to get an excellent one or just an okay one.
The local roaster I visited today had some Colombian beans on the list, but they were all out on the shelf, so I opted for the Kenyan beans as a second choice.
Have you tried Honduran beans?
