Synonym: Glera, Serprina, Prosecco Bianco, Prosecco Nostrano, Prosecco Tondo, Prosecco Baldi, Prosecco Lungo.
Commonly mistaken for: Gardana, Malvasia del Chianti, Malvasia Toscana, Malvasia Trevigiana, Prosecco-Malvasia.
Origin: The origins of this variety are uncertain; the variety could be native of the Trieste region around the zone of Prosecco (from which derives its name), but where, however, it was called Glera, from here perhaps it moved to the Veneto (Colli Euganei), where it was called Serprina, this is only one hypothesis; the other one suggests the inverse move, in 1772 for the first time it is cited in Consigliano Academy (in the province of Treviso) by the academician Malvolti Francesco. Today It is mainly grown between Valdobbiadese and Conegliano (northeast Italy), where it is the most common variety. This variety is not very homogeneous, in fact it used to be divided into “Prosecco lungo” and “Prosecco tondo”, within this variability there were groups of individuals so different both in vegetative and reproductive organs that they gave different names to the various biotypes: Prosecco Balbi, Prosecco dal peccol rosso e Prosecco rosa (this last one was cultivated in Dalmatia, but now it is practically extinct).
- Prosecco lungo (or minuto or slungo): vine characterized by low vigour; the bunches are large, long, not winged, semi-compact. The berries are not of homogeneous size, but with a strong and thick skin.
- Prosecco tondo (or Proseccon): vine characterized by high vigour; the bunches are large, long and winged. The berries are large with a thin skin.
Agronomic and environmental aspects: It has a preference for hilly areas, with a medium exposure and good humidity. The vines require VSP training system (Controspalliera) and cane pruning. High and constant yield, a summer pruning and a thinning of bunches is advisable to avoid possible attacks of pests and improve the quality of the fruit.
Diseases, pests and disorders: This vine is adaptable to different climates, but having an early time of budburst it can be susceptible to spring frosts and show hen and chicken and dropping off. Shows a good resistance to sour bunch rot. Susceptible to downy and powdery mildews and Flavescence Dorée. Can be attacked by mites, rhynchota and lepidoptera.
Growing Tip: fully open, cottony, of whitish green colour.
Leaf: medium-large size, wedge-shaped, 3-lobed or 5-lobed. Has a U or V-shaped petiolar sinus with lobes strongly overlapped, lateral superior sinuses shaped like a deep U, while the inferior (if there are any) are like an open V. The profile is undulating with involute lobes.
Bunch (Prosecco tondo): medium-large, of pyramidal form, winged, loose density of berries.
Berry (Prosecco tondo): of medium dimensions, round; thin skin, covered by bloom, of golden yellow colour and slightly spotted.
- VCR 101: Clone selected by “Vivai Cooperativi Rauscedo”; biotype “Prosecco tondo” characterized by medium-high vigour and constant productivity, big and long bunches with loose density of berries. Less susceptible to downy and powdery mildew.
The wine can be made in two different styles: dry or sparking (Spumanti), the latter is the most common. It is straw-yellow or slightly clear and gilded yellow in colour, fizzy, not very alcoholic, amiable and very fragrant. This variety is used in important DOC of the Veneto region, sometimes it is blended with other native white grapes, such as Verdiso: Colli di Conegliano, Colli Euganei, Conigliano-Valdobbianese, Montello and Colli Asolani and othes DOC: Bagnoli, Breganze, Gambellara, Piave.
