Glera is a long-standing synonym of northern Italys Prosecco grape, and the name by which it is now officially known. This green-skinned variety has been grown for hundreds of years in the Veneto and Friuli regions, most famously to produce sparkling Prosecco wines.
The Prosecco-Glera name change happened in 2009, when Prosecco di Conegliano-Valdobbiadene was promoted to full DOCG status (the highest level of Italian wine quality).
In light of this promotion, it was decided that the name Prosecco should be reserved exclusively for wines covered by Italys official Prosecco appellation titles, and should not be used for the grape variety. The European Union ratified this, effectively making it illegal for wine producers anywhere outside northeastern Italy to label their wines as Prosecco.
the Glera grape was known as Prosecco (more precisely Prosecco Tondo). The
variety has an unclear origin and an even more complicated ampelographic history
due to the fact that several distinct varieties have been called
“Prosecco-something” in northeast Italy since the 18th century. The grape is
late ripening and prone to both fungal diseases and water stress. It is widely
planted in the province of Treviso. Glera Grapes
is considered a semi-aromatic variety, although when grown on flat land with
unrestricted yields, it becomes rather neutral. If planted on south-facing
slopes with controlled yields, Glera produces wines with depth and character.
The wines are light, soft and refreshing with aromas of white flowers, lemon,
pear, apple and peach.
