Colli Bolognesi Pignoletto
Styles
Principal grape varieties
Terroir
Natural factors
- Argillaceous-calcareous substrate: Argille Scagliose with calcareous, arenaceous, and marnose masses on landslide-prone slopes; highly calcareous and silty soils in the Primi Colli.
- Vineyards between 50 and 400 m a.s.l.; the north–south orientation of the valleys promotes ventilation and predominantly east/south-east exposure of the vineyards.
Human factors
- Vine married to trees already in Roman times, later evolving toward trellis training, cordone speronato, and Guyot with short pruning.
- Pier de' Crescenzi (14th century) already described the «lively golden foam» of the local white wine, attesting to the sparkling style.
Product characteristics
- Argillaceous-calcareous soils impart a perceptible minerality; day-to-night temperature variations enhance the aromatic profile and preserve acidity in still wines.
- The frizzante/spumante version is made from grapes with moderate sugars and pronounced acidity; production by autoclave (Charmat) or bottle re-fermentation, the latter allowing for a natural haze.
Terroir / wine link
- Argillaceous-calcareous soils lend still Pignoletto a perceptible minerality, while day-to-night temperature variations enrich its aromatic profile.
