Origins of Prosecco grape variety
The Italian DM 21/07/2009 Glera grape variety replaced the name “Prosecco”. In this way, the Italian Ministry of Agriculture safeguarded the Designation of Origins “Prosecco” to avoid any kind of copying of one of the most famous products of the Made in Italy.
The origin of this grape variety is an uncertain white berry. Although it is currently associated to the Hills of the province of Treviso, it hasn’t arrived in this area before 1700.
Is it possible that this graoe variety comes from the province of Trieste, precisely in Prosecco (a municipality with the same name of the famous wine), where it was called Glera.
The most important productive zone today is the left bank of river Piave, between Valdobbiadene and Conegliano.
There are different varieties, Prosecco “tondo” and Prosecco “lungo”, that differs from the grape shape, Prosecco “Balbi” with round grapes with a rough size and the so called Prosecco dal peccol rosso.
