Suitability for cultivation and agronomic production
Dolcetto has a moderate vigor and a semi-erect to erect bearing. This variety has a moderate to high fertility that can be irregular. It is best to prune it short or moderately long with a sufficient trellising. In case of automnal rains, ripe berries tend to fall easily before harvest. Dolcetto is resistant to winter and spring frosts. However, it is sensitive to chlorosis.
Susceptibility to diseases and pests
Dolcetto is sensitive to downy mildew and powdery mildew. It is however less susceptible to grey and sour rot.
Technological potentiality
Dolcetto’s bunches are small to medium in size and moderately compact. The berries are also small to medium, simple-flavored, with a thick skin and a soft pulp. Dolcetto produces intensely colored, fruity, not very tannic, moderately alcoholic and moderately acidic wines that must be consumed quite quickly.
