Glera (grape)

Glera is a white variety of grape of Slovenian origin, which until 2009 was mostly referred to as Prosecco. Glera is grown mainly in the Veneto region of Italy, traditionally in an area near Conegliano and Valdobbiadene, in the hills north of Treviso.

History

The Glera grape is believed to be of Slovenian origin. The name may derive from the Slovenian word "glera", which means "chalky", a reference to the mineral-rich soils of the region where the grape is grown. The grape has been grown in the region for hundreds of years and is believed to have been used in the Roman era to produce a wine known as Pucinum, which was favored by the Roman author and naturalist Pliny the Elder.

Characteristics

Glera is a rather neutral grape variety which is mainly valued for its ability to undergo the Charmat method of sparkling wine production, retain its acidity and produce low alcohol wines. The grape is relatively easy to cultivate, although it has a tendency to produce high yields which can dilute flavor concentration and lead to wines of less character.

Use in Prosecco

The Glera grape is the main grape used in the production of Prosecco, a popular Italian sparkling wine. Prosecco was traditionally made from a mix of grape varieties, but since the establishment of the DOC regulations, the majority of the blend must be made from Glera. The wine is typically dry with notes of apple, pear, white peach, and apricot.

Viticulture

Glera is a late-ripening variety which is typically harvested in the second half of September. The grape has a high yield and is resistant to both cold and drought. It prefers hillside locations with a south-facing aspect and soils rich in minerals.

Synonyms

Over the years, Glera has been known under various synonyms including: Prosecco, Prosecco Tondo, and Glera Lunga.
