The San Cristoforo vineyard, flagship of Pietro Rinaldi's Barbaresco holdings, occupies prime terrain within the DOCG zone. Positioned to capture the region's distinctive diurnal temperature variation—essential for Nebbiolo's phenolic maturity and aromatic development—the vineyard benefits from southeast-facing slopes and well-draining, white-clay soils. The 2021 vintage presented a cooler, wetter growing season by recent standards, slowing Nebbiolo's ripening and concentrating aromatic complexity. Such challenging vintages often produce Barbarescos of particular elegance and finesse, with deeper perfume and fresher acidity than warmer years.

Following Piedmont tradition, fermentation occurred in large wooden vessels over extended periods, allowing systematic extraction of colour and tannin from Nebbiolo's notably thick skins. Following fermentation completion, the wine transferred to large Slavonian oak casks for maturation—a protocol designed to integrate the wine's naturally high acidity and assertive tannin structure. Oak contact typically spans two years, permitting gradual development and aromatic layering. Unfiltered bottling preserved the wine's full aromatic expression and cellaring potential.
