I have recently roasted Sumatran twice and it is the only coffee I have 
roasted that seems to have little to no crack - the beans just lay there 
getting darker and darker with no cracks, except for a few beans.  All the 
other coffees I roast have a distinct cracking period early on (about medium 
brown to dark brown).  Is the Sumatran coffee that different?
