Origin: Trentino, Italy
History: Nosiola is a white grape variety native to the Trentino region in northeastern Italy, with historical references dating back to the 16th century during the Council of Trent. Its name is believed to derive from the Italian word 'nocciola,' meaning hazelnut, reflecting the characteristic hazelnut notes in its wines. Traditionally, Nosiola was widely cultivated across Trentino; however, over time, its cultivation has become more concentrated in specific areas such as the Valle dei Laghi, Colline di Trento, and Pressano. The grape is notably used in the production of both dry white wines and the renowned sweet Trentino Vino Santo, made from dried grapes affected by noble rot.
Appearance: Medium-sized, spherical berries with a greenish-yellow, thin yet firm skin.
Growing Traits: Nosiola thrives in hilly, sunny, and breezy terrains, particularly in the Valle dei Laghi and Val di Cembra regions of Trentino. It is a mid to late ripening variety that buds early in the growing season, making it susceptible to spring frosts. The grape is sensitive to humid conditions, which can lead to fungal infections such as sour rot and powdery mildew. Despite these challenges, Nosiola's thick skins and late ripening make it suitable for passito-style winemaking, as the berries can undergo desiccation for the production of Vin Santo.
