Depends how you like your roast. Espresso has no defined roast. Some are just medium roasted at best. I think it's the mixture of beans and roasting that makes an ideal blend. Brasil and Guatamala are beans I love in my espresso blends, perhaps with no cracking in them? I do not like the smoky notes in espresso from a dark roast.

Just look at all the big brands both bagged and fresh roasted, the color runs the spectrum for depth of roasting from oily-black to smooth brown...
