First, let's clear something up - there really is no such thing as an "espresso" bean. Espresso is a type of drink made with a heavily roasted coffee bean. It's not a variety of coffee bean that can be grown. So with that out of the way we can now move on to the difference between regular coffee beans and espresso beans. The main difference is that espresso beans are roasted for longer, which gives them a more intense flavor. They are also ground much finer than regular coffee beans, making espresso the perfect coffee bean for making espressos, which tend to have a more robust flavor profile because they are roasted longer. Now that we know the difference between regular coffee beans and espresso beans let's talk about some of these differences as it relates to chocolate-covered espresso beans. Most notably, it's going to be the flavor profile. Espresso beans have a much stronger flavor profile than regular coffee beans, which is why they are typically used for making chocolate-covered espresso beans - it helps bring the flavor of the bean to the forefront, making it an equal match for the chocolate.
