Not much.  The common myth/misunderstanding here is that there are even espresso beans.  There is no such thing as an espresso plant, so it can't produce espresso beans.Beans that you use to make espresso are the same as regular coffee beans.Espresso is a method in which coffee is ground and brewed.  We have several blends that we made with shots of espresso in mind, but any coffee can be used to make espresso.  Some are more preferable than others.
