Manzoni Bianco is a white grape variety that was created by the Italian grape breeder Professor Luigi Manzoni in the early 20th century. It is a hybrid grape variety resulting from a cross between two other grape varieties: Riesling Renano (Rheinriesling) and Pinot Bianco (Pinot Blanc). 

Varietal Origin: Manzoni Bianco was developed in Italy, specifically in the Veneto region, by Professor Luigi Manzoni. He conducted extensive grape breeding experiments in the 1920s and 1930s, resulting in several new grape varieties, including Manzoni Bianco.

Taste Profile: Wines made from Manzoni Bianco grapes typically have a crisp and refreshing character. They often exhibit citrus and green apple notes, with a lively acidity that makes them well-suited for fresh and vibrant white wines. The taste profile can also include floral and mineral hints.

Regional Styles: Manzoni Bianco is primarily cultivated in northern Italy, particularly in the Veneto and Friuli-Venezia Giulia regions. It is used to produce both varietal wines and as a blending component in white wine blends. The grape's ability to retain its acidity even in warm climates contributes to its popularity among winemakers.

Interesting Fact: Professor Luigi Manzoni was a pioneer in grape breeding, and his work led to the creation of several grape varieties, including Manzoni Bianco (Manzoni-1.50) and Manzoni Moscato (Manzoni-6.0.13). These grape varieties were developed to combine the desirable characteristics of their parent grapes while adapting to the local climate and terroir.
