The key is that maduro is a process. I think what dictates the flavor has more to do with what variety of tobacco it is than the fact the leaf was processed into maduro leaf. The rest of the blend plays a part in what we taste too but plain and simple....San Andres, CT or PA broadleaf, Habano, criollo, corojo, etc all taste different. I think the familiar "maduro" flavors most people think of are the taste of broadleaf.
