Winery Ca' del Baio

The Grasso family has been connected to these hills for generations: Giuseppe Grasso's arrival in Treiso is documented in 1870, and in the following decades the family progressively selected and vinified individual parcels. In the 1980s and 2000s the winery refined the separation of grapes by cru, and in 2008 introduced experiments with Riesling. The revival and modern visibility of the winery are linked to the work of Giulio Grasso, and today management also involves the family's daughters.

It favors a sustainable approach to viticulture, eliminating chemical weed control, using cover crops, and prioritizing biodiversity and soil conservation. In the cellar, fermentations with indigenous yeasts are encouraged and the use of sulfites is limited to preserve the character of the vintages and their ageing potential.

The estate and most of its vineyards are located in Treiso, near Barbaresco and not far from Neive. The estate's vineyards fall within historic crus such as Vallegrande, Asili, Pora, Marcarini, Ferrere and Trestelle; the soils are typically calcareous marls that characterize the Barbaresco area.

Giulio Grasso was named "Winemaker of the Year" by the Gambero Rosso guide.
