Marzemina Bianca is an ancient white grape variety with somewhat mysterious origins. Some believe it arrived from Burgundy and later spread to Germany, Austria, Switzerland, and northern Italy. Others consider it synonymous with Chasselas Doré, further adding to the uncertainty about its true ancestry.
Historically, Marzemina Bianca was widely cultivated in the Veneto region, particularly in the provinces of Treviso and Vicenza, including the Euganean Hills and the Lison-Pramaggiore area. In local dialect, it is sometimes referred to as Sciampagna due to its suitability for making aromatic sparkling wines.
In the Breganze area, Marzemina Bianca is occasionally passed over Torcolato pomace - the rich pomace from dried Vespaiola grapes used in the famed dessert wine - adding body and aromatic complexity to the wine. Today, it is typically used in blends with other white grapes such as Glera (Prosecco), Verduzzo Trevigiano, Chardonnay, Verdiso, and Vespaiola.
The grape has large, spherical, white berries with a thick, golden-yellow, waxy skin. Bunches are medium-sized, elongated pyramids, often winged and moderately compact. The vine has medium-sized, orbicular, three-lobed leaves.
Though rarely vinified on its own, wines made from Marzemina Bianca tend to be pale yellow, with an intense, fruity aroma. On the palate, they are fresh, tangy, and slightly bitter, making them refreshing and versatile, especially in sparkling formats.
