Uva rara

The Uva rara (rare grape) is used in limited quantities together with Croatina and Barbera in the wine Bonarda.

Historical background

The Rare Grape is a grape variety cultivated for many centuries in the provinces of Novara and Vercelli in Piedmont and in the province of Pavia in Lombardy.

The Rare Grape is the name that in some areas was given to the Bonarda grape adapted to specific geographic areas for many years, and it was considered a relative grape if not the same. This is due to an incorrect evaluation of 1877 by Di Rovasenda, which confused her with Bonarda of Gattinara. The same mistake was made in 1906 by Molon.

Today, ampelographers all agreed to believe that the two vines are separate and different even though some synonyms are now accepted in popular vocabulary such as Bonarda of Cavaglià, Bonarda of Gattinara, Balsamina and others less used.

Vegetative characteristics

Medium-late sprouting (between the second and third decades of April). Blossom in the middle age (between the first and second decades of June). Late-middle veraison (after mid-August). Maturation of grapes on average or medium-late (late September, first decade of October). The most effective cultivation system is expanded guyot. The vine is very vigorous, even too much in the period involved in flowering, it is subject to a strong flower lost to be kept under control. The vine is sensitive to oidium, on average to peronospora, but is resistant to rotten and botrytis and climatic adversities such as hailstorm. It is generally cultivated on various types of soils, preferably clayey, on low hills at approximately 200-300 meters.

Large pentagonal leaf with long median lobe, five-lobe (but more often seven or nine lobe the leaves of the base of the plant) with large and deep breasts; closed petiole breast, with U + V base shape and form of lira. Bunch of variable size but generally of medium size, conical, often truncated, short, very sparse; mid-length peduncle, light yellowish green, sometimes blurred with red as the rachis.
