The
fine wines of the Langhe > Vines > Grignolino vine
Barbesino (long ago).
Geographic
distribution
Some considerations about
the amphora which were found in Piedmont are very
useful in order to follow wine trade routes,
especially after the Roman colonization.
Morphological
characters
Bud: greenish
white, with a rosy or carmine red edge, lanuginose
apex. Whitish green, with red teeth top and rosy
shades, inferiorly between very much lanuginose
and cottoned, apex leaves (1-3). Golden-yellow,
with copper shades (often with red edges),
inferiorly lanuginose, basal leaves (4-5).
Adult leaf: of medium size (sometime
medium-large), pentagonal, tri- or more often
five-lobed; U- or lyre-shaped central womb, closed
or with slightly superimposed borders; its
superior lateral wombs are U- or lyre-shaped
(sometimes with superimposed borders); its
inferior lateral wombs are slightly profound and
v-shaped, or sometimes more profound and u-shaped.
Its border is cup-shaped; its surface is
abundantly bubbly, of light green colour, with red
main nervations. Its teeth are pronounced,
irregular, large-based and with rectilinear
margins. Its inferior page has bristly nervations.
Ripened grapes: of medium or medium-large
size, pyramidal, sometimes prolonged, often with
very much developed wings, compact or very much
compact; its peduncle is short and robust, of
green colour with red shades.
Acinus: medium-small (1,6 g), short
ellipsoidal (d.e./d.l.=0,93); its peel is very
pruinose and of a colour between violet-black and
violet-red, often not uniformly distributed; there
are many grape seeds. Environmental and
pathological reasons influence grape colour
intensity and uniformity, as well as the genotype
effect does.
Phenology
Germination:
medium (second decade of April).
Flowering: medium (between the first and the
second decade of June).
Turning to dark colour: medium-late
(second-third decade of August).
Grape maturation: medium or medium-late (end
of September-first decade of October).
Cultural
attitudes and utilization
Vigour: medium. Fertility
and production: between medium and high, often
alternating; scarcely fertile at basal gem and
femminelle level.
Plant-culture and pruning: counter-espalier
with mixed pruning or Guyot type, with only one
capo fruiting 10-12 gems.
Multiplication behaviour: generally good,
although some disaffinity problems, with some
Kober 5BB and 420 A clones, have been signalled;
vigorous grafts are usually utilized for this vine
(rupestris du Lot, Golia).
Susceptibility to adversities and phytopathy:
rather tolerant to peronospora but susceptible to
oidium and very susceptible to cinereous Botrytis
and grape acid rot; it often presents a phenomenon
of rachis drying; moreover, it is sensible to iron
chlorosis in some years and environments. This
vine, in order for its grapes to mature and to be
coloured rightly, must be grafted under good sun
expositions and in dry grounds.
Oenological attitudes: vinified grapes give
young wines, of a ruby red colour, sometimes with
orange reflections, and with a slightly floral
smell, with characteristic pepper notes; their
taste is dry and very tannic. Together with
Barbera and/or Freisa, wines of a more intense
colour and higher harmony are obtained, which are
also suitable for a moderate ageing.
