Winery Azienda Agricola Zeni

The winery originated in the village of Grumo and is historically linked to the Zeni family; the company's website states that the winery was founded by Roberto Zeni in 1882. Production and management have been passed down through several generations of the family, and over the years the winery expanded its operations to include traditional-method sparkling wines and an artisan distillery. In the 2000s the winery began a shift toward more natural practices and a gradual conversion to organic viticulture.

A commitment to sustainable agricultural practices and respect for the land, combined with a family tradition: the winery aims to showcase indigenous grape varieties and organic practices to produce wines expressive of the terroir, while maintaining carefully managed ageing techniques.

Based in the Piana Rotaliana and colline avisane. The vineyards include both the alluvial plain of the Noce/Adige and slopes with Dolomitic soils. Among the crus is Maso Nero, which is also used for sparkling wine production and aging.

The winery and its wines have been featured in competitions and guides; the winery's website lists awards and press mentions.
