Masseto is located in Bolgheri, Tuscany, within the Ornellaia estate's broader holdings, where clay-limestone soils and a Mediterranean climate favour Merlot's full ripeness. The 2022 growing season delivered ideal conditions: cool spring temperatures limited frost risk, a warm April–May encouraged flowering, and a relatively dry summer with moderate August rains ensured balanced phenolic development without excessive alcohol. The vineyard practises sustainable farming, including cover-cropping, natural pest management, and selective pruning to optimise canopy and fruit concentration. Grapes were harvested by hand in mid-September at peak ripeness, with careful sorting in the vineyard and cellar to select only the finest berries for this single-varietal wine.

Masseto grapes fermented in temperature-controlled stainless-steel tanks using selected yeasts, followed by extended maceration (around 30 days) to extract colour, tannin, and aromatic complexity. Malolactic fermentation began naturally or under controlled conditions, contributing secondary flavours. The wine was then transferred to new and lightly-used French oak barrels (typically 100% new for Masseto) where it matured for approximately 18 months, receiving regular bâtonnage (lees stirring) to build richness and texture. Following barrel maturation, the wine underwent a short period of stainless-steel or bottle resting before final assembly and bottling.
