The grape that makes Prosecco sparkling wines was for many years called Prosecco. But this caused the Italian producers of Prosecco difficulties when they realised that like any other grape variety people were planting it elsewhere and referring to it as Prosecco. So they applied to the EU to turn "Prosecco" into a region and use a synonym, Glera, as the official grape name. Elsewhere, most notably Australia, it can still be referred to legally under the original name. The grape largely makes sparkling wines and for the most part from the Charmat (tank) method, though traditional method sparkling wines are also found.
