Sorelle Bronca is a wine producer based in the Prosecco di Conegliano Valdobbiadene DOCG zone in the Veneto region of northeastern Italy. This family-run estate operates within one of Italy's most prestigious sparkling wine appellations, focusing exclusively on the production of Prosecco from the traditional Glera grape variety.

The Prosecco di Conegliano Valdobbiadene DOCG represents the historic heart of Prosecco production, encompassing steep hillside vineyards between the towns of Conegliano and Valdobbiadene. This zone achieved DOCG status in 2009, recognizing its superior terroir characterized by varied soils ranging from clay and sandstone to moraine deposits. The area's unique microclimate, influenced by the nearby Alps and Adriatic Sea, creates ideal conditions for Glera cultivation. Wines from this appellation typically display greater complexity and mineral character compared to Prosecco from broader DOC zones.

The estate currently produces an Extra-Dry Prosecco di Valdobbiadene DOCG, working exclusively with Glera grapes. Extra-Dry represents a traditional sweetness level in Prosecco production, containing 12-17 grams of residual sugar per liter, offering a balanced profile that bridges the gap between the bone-dry Brut and sweeter Dry styles.

Veneto is located in northeastern Italy, stretching from the Dolomites to the Adriatic Sea, with Venice as its capital city. The region ranks among Italy's largest wine producers by volume, encompassing diverse terrain that includes Alpine foothills, flat plains, and the famous Valpolicella hills near Verona. Veneto's winemaking heritage spans centuries, with Roman settlements establishing many of the viticultural practices still used today.

The region benefits from a continental climate moderated by the Adriatic Sea and Lake Garda, creating conditions suitable for both sparkling and still wine production. Key appellations include Prosecco DOC and the prestigious Prosecco Conegliano Valdobbiadene DOCG in the north, Soave DOC for white wines, and Amarone della Valpolicella DOCG and Valpolicella DOC for reds. The varied topography ranges from volcanic soils in Soave to limestone and clay compositions in Valpolicella, each contributing distinct characteristics to the wines.

Glera dominates sparkling wine production, particularly in Prosecco appellations where it creates wines ranging from bone-dry to off-dry styles. Red wine production centers on indigenous varieties like Corvina, often blended with Rondinella and Molinara in traditional Valpolicella blends. The region is distinctive for its appassimento technique, where grapes are dried to concentrate flavors for Amarone production, and for pioneering modern Prosecco methods that transformed a regional specialty into an internationally recognized sparkling wine style.

Prosecco Conegliano Valdobbiadene DOCG represents the historic heartland of Prosecco production in the Veneto region of northeastern Italy. This DOCG zone encompasses the hillside vineyards between the towns of Conegliano and Valdobbiadene, located about 50 kilometers north of Venice. The appellation received DOCG status in 2009, recognizing it as the premier area for Prosecco production and distinguishing it from the broader Prosecco DOC designation.

The region's steep hillside vineyards benefit from a continental climate moderated by Alpine influences, with significant diurnal temperature variation that helps preserve acidity in the grapes. The soils vary from limestone and clay in the valleys to sandstone and conglomerate on the hillsides. Glera is the primary grape variety, comprising at least 85% of the blend, with small amounts of Verdiso, Bianchetta Trevigiana, Perera, Glera Lunga, and Chardonnay permitted. Production follows the Charmat method, with secondary fermentation occurring in pressurized tanks to preserve the wine's fresh, fruity character.

Wines from this appellation typically display bright acidity and delicate perlage, with primary fruit flavors of green apple, pear, and citrus. The extra dry style, which contains 12-17 grams per liter of residual sugar, offers a subtle sweetness that balances the natural acidity. These Proseccos generally show more complexity and finesse compared to those from the broader DOC zone, with mineral undertones reflecting the varied hillside terroir and traditional winemaking practices of this historic region.
