THE
VINIFICATION PROCESS
The picked grapes
are being crushed by a pneumatic press, with
a soft pressing. The must is being left rest
for a night. The day after, the limpid part
must be brought in the fermentation tanks, which
are thermoconditioned. The turbid part, after
filtration, is being put together the limpid
part. At this moment the selected yeasts of
Prosecco are being added and, at a temperature
of 18°-19°C, the alcoholic fermentation
begin. This fermentation lasted 8-10 days (it
depends to the vintage). When it finished, the
wine is being centrifuged, filtrated and put
in stainless steel in stocking.
To produce Frizzante and Spumante wine, we
have to use special tanks in stainless steel,
which are called "autoclave". To start
this process, we have to take the base Prosecco
(alcoholic gradation: about 9,50%) from stocking-tanks,
than we add the yeasts of Prosecco and cane
sugar to produce Spumante, while for producing
Frizzante (for Italian law's obligations) we
have to add concentrated grape's must instead
of adding cane sugar.
In order that the fermentation start, the wine
must reach the 18°-19°C of temperature.
When the new Frizzante or Sumante wine will
reach the pressure, the alcohol and the residual
sugar that we want, we stop alcoholic fermentation
by cooling, and in the same time we make start
the tartaric stabilization at the new product
(minimum 10 days). Now both Spumante and Frizzante
are ready to be bottled.
