It is made from a vine of the same name, Lambrusco di Sorbara, which is a native variety of remote origins. It grows in sparse, conical clusters bearing spherical fruits, the abundance of which varies from year to year (while the grapes retain the same size of a few millimeters).
This is due to a flowering anomaly, that can give rise to a considerable loss of fruit. It has now been ascertained that the phenomenon, typical of Lambrusco di Sorbara, is caused, above all, by the sterility of the pollen. In some years, it has been known to bring about a drop of over 30% in the amount of grapes harvested for production.
But it is this peculiarity that makes it so outstanding, memorable and particularly admired. It stands alone among the range of Lambrusco wines and shares its qualified position with other noble vines cultivated in Italy and France (the prime example being Picolit).
As we have said, production is always limited and, in some years, it is extremely hard to come by. But what is lacking in quantity is more than made up for in quality, always of the highest. To facilitate fertilization the Sorbara vine is cultivated with a percentage of Salamino Lambrusco, the vines growing side by side in the same vineyard.
