Area of Alessandria (in particular, Tortona Hills).
Shoot: the apex is scarcely bloomy, green-whitish
coloured with few pink shades. The upper small leaves
(from 1 to 3) are folded as a cup, green-whitish with
bronze shades, bloomy in the lowest part. The bottom
small leaves (4-5) are folded as a cup, green-bronzish
coloured, bloomy in the lowest part. The herbaceous
shoot shows clear dark pink streaks on the back half.
Adult leaf: average or average-small size,
pentagonal, trilobed or five-lobed; lobes have sharp
ends: lateral lobes are divergent, the middle lobe is
often elongated; V-shaped open petiolar sinus (in flat
leaves); narrow upper lateral sinuses, U+V bottom, in
some cases with a small tooth; V-shaped lower lateral
sinuses. Smooth surface leaf blade (or averagely bullous
in some clones), definitely folded as a cup, green with
pink-coloured veins in the lowest part. Averagely prominent
teeth, with a narrow base and margins that are concave
on one side and convex on the other side. Lower leaf
surface is covered with down from arachnoid to bloomy,
typically velvety to the touch.
Ripe bunch: usually large, pyramidal and winged,
elongated shape, on average with a few berries; average
length stalk, green coloured like the rachis.
Grape berry: average size (2,3 g), short and
ellipsoidal (d.e./d.l.= 0,95), with solid pruinose skin,
dark blue coloured.
Please note: Croatina shows intravarietal variability,
evident in plant vigour, in leaf size and furriness,
but above all in the size of bunches and berries. Once,
a distinction was made between large Croatina and small
Budding: average-late or late (third ten days
Flowering: average period (between the first
and the second ten days of June).
Onset of ripening: average period (second ten
days of August).
Grape ripening period: average-late (first
ten days of October).
