Biserno di Biserno IGT Toscana

When Lodovico Antinori — architect of Ornellaia and Masseto — sold those estates and turned his attention to the stonier hills of Bibbona, he made a deliberate break: where Bolgheri's template demands Cabernet Sauvignon or Merlot at the fore, the Biserno

flagship inverts that hierarchy, placing Cabernet Franc at roughly one-third of the blend alongside equal parts Cabernet Sauvignon and Merlot, with a small Petit Verdot component (~6%).

The estate sits at approximately 90 m elevation in Alta Maremma, on soils of calcareous clay rich in calcium carbonate interlaced with the mineral-dense 'Bolgheri Conglomerate' — a stony, gravelly matrix that stresses the vine and concentrates aromatic intensity.

Constant Tyrrhenian Sea breezes moderate summer heat and suppress humidity, preserving the Mediterranean herb register that defines the house style.

Grapes are hand-harvested, sorted on conveyor, and vinified plot-by-plot in temperature-controlled stainless steel with 3–4 weeks maceration at max 28°C. Malolactic fermentation runs spontaneously, split ~65% in barrique / 35% in steel. The wine then ages 15 months in French oak barriques, approximately 70% new, followed by a minimum 12 months in bottle before release.

The estate deliberately operates outside the Bolgheri DOC boundary — a structural choice, not an oversight — allowing the varietal freedom that makes Cabernet Franc dominance possible under Toscana IGT.

The blend mirrors the 2021 composition; expect the characteristic Mediterranean herb intensity and dense concentration of the estate's recent releases, with a drinking window extending well into the 2030s.
