The D.O.C. and IGT wines are products that have to
comply to a set of well-estabilished production rules
and standards. In particular, the D.O.C. wines have
to be compliant to a set of very restricted constraints
in order to guarantee their quality: kind and percentage
of grapes used, hectoliters of wine produced for each
hectare, minimum alcoholic strength, ageing process
adopted and chemical peculiarities.
