The estate sits at Località Ginestra in Monforte d'Alba, one of the eleven communes whose vineyards make Barolo DOCG. The Grasso family's 42 hectares climb the southern face of the Ginestra hill, with 18 of those hectares planted to vine and the rest left to wood and meadow. The vineyards lie inside the Langhe-Roero-Monferrato cultural landscape inscribed by UNESCO in 2014, and the family's plots already appear on Lorenzo Fantini's early twentieth-century map of the Langhe's best growing sites.
Production runs to roughly 90,000 bottles a year across seven wines. Three are Barolo DOCG: the long-aged Riserva Rüncot, the Gavarini Chiniera from a south-facing parcel of medium-textured calcareous-sandy soil, and the Ginestra Casa Maté from the deeper calcareous-clay soils nearer the village. Alongside them sit a Barbera d'Alba DOC Vigna Martina, a Langhe DOC Nebbiolo, the Dolcetto d'Alba DOC dei Grassi planted in the 1980s replanting cycle, and the Langhe DOC Chardonnay Educato, whose vineyard was planted in 1986 and first bottled in 1990.
The Grassos took back hands-on viticulture in the early 1980s, replanting Nebbiolo, Barbera and Dolcetto vineyard by vineyard and bottling the first single-vineyard wines in 1978. Vines run on Guyot at 4,500 plants per hectare. Fermentation happens in temperature-controlled stainless steel with daily pumpovers; the Barolos then age in 25-hectolitre Slavonian oak botti, while the Chardonnay splits between steel and French barriques.
Two phrases recur on the family's own site: contadini prima e produttori poi, farmers first and producers second, and an insistence on respecting the work of those who came before. Six members of the family are named on the home page: Elio, Gianluca, Marina, Francesca, Martina and Anna Grasso. Visits are by appointment only, Monday to Friday, arranged through the request form on the official site rather than a third-party booking platform.
