Prosecco
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).
Biotype descriptions:
-
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.
Description:
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.

Wine
characteristics:
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.
