This wine is produced from the Lambrusco Grasparossa variety. Although not possessing great vigour, the vine is distinguished by a special characteristic: with the arrival of autumn, not only the leaves turn red, but also the stalk and pedicels.
The relevant productin rules permit the Lambrusco Grasparossa vine to be cultivated alongside a modest percentage of Lambrusco and Fortana ("Uva d’Oro") varieties. None the less the wine is essentially derived from the vine of the same name. The sparse, conical-shaped cluster is medium in length with roundish fruits. The grapes range from plummy dark blue to blackish, have a thick skin and contain a medium juicy, sweetish, slightly acidulous pulp.
Due to its lack of vigour, the Lambrusco Grasparossa vine is best cultivated in smaller vineyards, where it does well, even on rather poor soils, such as those on the lower slopes of the Modenese hills.
It bears up well to climatic and other adversities, and matures fairly late, after waiting to capture the very last rays of autumn sunshine (years ago, harvesting went on well into November).
