| Productivité |
In the wine-growing areas of the provinces of Novara and Vercelli, the practitioners distinguish between two subvariates of this vine: the one with gems well developed and protruding, the other with opposite characters (locally called "a short gem"); And carefully eliminate the second, as less productive. Probably because of this continuous selection, as well as for particularly favorable environment conditions, the productivity of "rare grapes" in the aforementioned provinces is regular and discreetly abundant. In the province of Pavia, however, it complains of a production usually less than normal, due to the sanding, which is so frequent and accentuated that the bunches are excessively spatulate. In Oltrepò pavese, therefore, it would be - as the grape is valuable - to set up a careful selection, possibly with the import of marzas from the province of Novara. |
| Zones de culture |
It is widespread in some Piedmont areas and in Oltrepò Pavese. |
| Histoire |
The rare grape is a grape rooted for many centuries in the provinces of Novara and Vercelli in Piedmont and in the province of Pavia in Lombardy, where it is often confused with Bonarda and Creatina. This is due to an erroneous evaluation of 1877 by Di Rovasenda, which confused her with Bonarda of Gattinara, even though she used a double name to emphasize a different hypothesis. The same mistake was made in 1906 by Molon. Recently, however, there is no doubt that the two vines are different and have no kinship in 1906, it considered the Rare Grapes a synonym for the Bonarda vine. Today it has been established that there is no kinship between the two even though some accepted synonyms are now accepted in popular vocabulary such as Bonarda di Cavaglià, Bonarda di Gattinara, Balsamina and others less used. |

Main ribbon color: top, green; On the bottom, light green (with some slight rose shades in the pavone clone). Medium-sized, irregular, broad-centered teeth with straight margins.

| Notes |
Resistance to adversity: it has normal resistance to mildew, lacking in ozone. It is subject (especially in the rainy and cold springs) to the flowering of flowers; It is a disadvantage, however, that, as has been said, is much more lamentable in the wine-growing area than in that Novara-Vercellian wine region. It resists fairly well to hail strokes (unheated healing) and rotten grapes, even in fruit. |
