Morphology
Bud: apex cottony, greenish-white edges just tinted pink.
Apical leaves (from 1 to 3) greenish-white, with shades of pink at the edges, inferior cottony.
Basal leaves (4-5) greenish-white, woolly inferiorly, often with a tooth in petiolar sinus.
.
Adult leaf: medium-size or medium-large, wedge-shaped or pentagonal, with 3 or 5 lobes, depending on clones; narrow petiolar sinus U or U+V, often with a tooth ; upper lateral sinuses called “a lira” (often with a tooth) or V-shaped, in the clones with less incised leaves; U-shaped or V-shaped lower lateral sinuses, more or less profound.
The flap has dark-green surface, profile distinctly lobed as a cup and lobes a little twisted. Teeth quite pronounced, irregular, straight edges. The page below has a hairiness arachnoid-like on the edge and a slight softness near the main veins.
Bunches at maturity: medium-size or small-to-medium, depending on the clones, cylindrical or pyramidal, with one or two short wings, short, compact; green and short peduncle.
Grape: medium-small (1,6 g), short and ellipsoidal ( d.e./ d.l.=0.93).
Peel ery waxy, yellow-green, with a grey-golden shade when exposed to the sun.
Phenology
Budding: average age (second week of April)
Flowering: average age (between the first and second decade of june)
Veraison: mid August
Grape ripening: averagwe age (by the end of September
Cultural attitudes and utilization
Vigour: high, shoots grow quickly and sometimes are fail, the vegetation is luxuriant.
Fertility and production: high and constant, the basal buds are productive as well as female.
Breeding and pruning: it adapts to various forms of breeding and pruning, f. e. pruning by Guyot (head to the fruit of 12 or more buds) or cordon system, high and more expanded, generally less able to reach the best quality results.
Reproductive behaviour: good with most of the rootstocks; the moderately vigorous are advised.
Susceptibility to adversity and plant diseases: generally fairly tolerant against “oidio” both on the cluster and on the branch, the delicate skin of the grape makes it easily susceptible to suffer mechanical damage or something due the attack by pesticides.
Oenological aptitudes: from the Cortese grape we obtain quiet wines, sometimes fresh and light or higher structure, personality and elegance and, more rarely; dry sparkling wines.
