Ferghettina produces sparkling wines in Franciacorta, the prestigious appellation in Lombardia known for méthode champenoise Chardonnay and Pinot Nero blends. The winery's flagship releases—Franciacorta Riserva 33, Franciacorta Eronero Brut, and Franciacorta Extra Brut—demonstrate the region's capacity for refined, structured bubbles. The Riserva 33, built on Chardonnay, and the Eronero Brut, centered on Pinot Nero, both achieve complexity and precision. The Extra Brut, a Chardonnay-Pinot Nero blend, balances acidity and minerality. These wines have been assessed by Wine Spectator, Wine Enthusiast, Decanter, and Wine Advocate, reflecting the technical rigor and consistency of Franciacorta's traditional sparkling wine production.
