The white grape variety originates from France. Although it has slight morphological differences in leaves and shoots compared to Chardonnay, it has an identical DNA profile. Morillon can be described as a variety or clone of Chardonnay. In Austrian Styria, Chardonnay is traditionally referred to as Morillon and is still partly regarded as independent there. However, both designations are also used by some producers in order to document a difference, if necessary, to a qualitatively "better" wine then designated as Chardonnay. In the other Austrian provinces, however, the name Morillon plays no role.
