Kuna Prosecco viinamarju kasvatati ka teistes piirkondades ja riikides, siis segaduse vältimiseks anti Prosecco viinamarjale ametlikult uus nimi Glera.
Freshness and ripeness are both requirements for making quality Prosecco, and so the best drier styles originate from sitesat higher elevations with greater day-night temperature variations, sometimes on more calcareous soils.
Although the name is derived from that of the Italian village of Prosecco near Trieste, where the grape may have originated, Prosecco is mostly produced in the Veneto region, mainly in Treviso province.
