In the steep, terraced hills between Conegliano and Valdobbiadene, where the vineyards are so precipitous that almost every task must be done by hand, two sisters have quietly built one of the most respected estates in all of Prosecco. Antonella and Ersiliana Bronca took over their father Livio's property in 1988 and have spent the decades since transforming a family tradition into a living argument for what Prosecco can truly be.
A Family Legacy Reinvented
The Bronca family has farmed these hills for generations, but Antonella and Ersiliana have shaped the estate in their own image. Joined by Antonella's husband Piero and Ersiliana's daughter Elisa, who trained as an oenologist, the family manages every aspect of the estate's 20 hectares with an eye toward quality and ecological responsibility. They converted to organic farming early, eliminating synthetic chemicals from the vineyards and embracing cover crops and plant biodiversity as tools for soil health.
The Valdobbiadene Terroir
Sorelle Bronca's vineyards sit within the Conegliano Valdobbiadene Prosecco Superiore DOCG zone, which in 2019 was recognized as a UNESCO World Heritage landscape. The estate includes notable parcels such as Scandolera and the single-vineyard site Antonella, located at Rua di Feletto. These steep hillsides, with gradients up to 60 percent, force slow, careful work but reward patience with fruit of exceptional concentration and aromatic clarity.
Winemaking with Purpose
Harvest is done entirely by hand, with fruit collected in small crates to preserve integrity. In the cellar, the sisters experiment with spontaneous fermentation, study natural vine defense preparations, and practice intercropping techniques drawn from ancient agricultural traditions. Their Glera-based wines, including the bone-dry Particella 232 cuvee and the extra-dry Modi, are made using advanced charmat fermentation that preserves primary aromatics while avoiding heavy-handed manipulation. The result is a range of Proseccos that are floral, precise, and genuinely site-expressive.
Why They Matter
Sorelle Bronca have long been advocates for treating Prosecco as a serious wine with real terroir, not simply a category defined by volume and price. Their approach, rooted in organic farming, hand labor, and relentless curiosity, makes them essential for anyone who wants to understand what the Valdobbiadene hills are capable of producing.
