The Manzoni Rosa grape variety was developed in the 1930s through the hybridization of indigenous grape varieties from the Marca Trevigiana region and other grape varieties from different origins. This was part of experiments aimed at improving the resistance of vines to adverse conditions and enhancing the organoleptic qualities of the resulting wines. These experiments, conducted by Prof. Luigi Manzoni of the Conegliano School of Enology, led to the creation of a whole family of grape varieties known as Incroci Manzoni. Manzoni Rosa is one of these and was obtained by crossing Trebbiano Romagnolo and Traminer Aromatico. The grape variety, identified as Incrocio Manzoni 1-50, is now mainly cultivated in the Triveneto region and is included in the blends of some denominations, including Alto Livenza IGT. The aromaticity of Traminer Aromatico, combined with the freshness and structure of Trebbiano Romagnolo, has resulted in a grape variety with surprising versatility and a unique color.

From an ampelographic perspective, the Manzoni Rosa grape variety has medium-sized, orbicular, trilobate leaves. The cluster is medium-small, pyramidal, and moderately compact, with small, spheroidal berries that have medium-thick, pruinose, and pinkish skins. Wines made from the Manzoni Rosa grape variety have straw-yellow to golden reflections and pronounced notes of rose and apricot on the nose. On the palate, they are full-bodied, with balanced sweetness thanks to a pleasant, fresh taste. The finish has a characteristic aftertaste of bitter almond.
