Collemezzano, Biserno and Campo di Sasso
The Biserno Project was born in 2001 in Bibbona (LI) when brothers Piero and Lodovico Antinori, together with their nephew Niccolò Marzichi Lenzi (now CEO), recognized the great potential of the territory. With instinct and passion, combined with centuries of family experience in the world of wine, they began a parcel-by-parcel study that would later lead to the establishment of three distinct entities: Tenuta di Biserno, Campo di Sasso, and Collemezzano.
The estates extend across the municipality of Bibbona, bordering to the north the historic village of Bolgheri, in Upper Maremma. The terroir is extremely diverse, with alluvial and marine characteristics—rich in sands and clays—or of aeolian and volcanic origin. This geological richness, com- bined with the estates’ different microclimates (which benefit from varied exposure, latitude, and proximity to the sea), creates an ideal environment for cultivating grapes of outstanding quality and strong identity.
The vineyard of Tenuta Collemezzano is one of the most suitable in the region, located just a few kilometers north of Bibbona. The decision to manage it as a cru is recent, although the 5 hectares of vineyards date back to the mid-1990s. The selected varieties are classic Bordeaux types, which thrive in soils featuring a balanced mix of pebbles, sands, silt, clay, and enriched with minerals. Produced only in the best vintages and resulting from meticulous vineyard selection, Collemezzano is the perfect expression of its original terroir.
Tenuta di Biserno covers about 40 hectares at 90 meters above sea level and is where it all began. The soils, mainly alluvial and clay-limestone, create an ideal environment for the selected varieties: Cabernet Franc, Merlot, Cabernet Sauvignon, and Petit Verdot. The vineyard’s varied exposures and its distance from the sea deeply influence the varietal expression: hence the decision to split production into Biserno – the company's most prestigious and representative wine – and Pino di Biserno, which conveys the territory in a more dynamic way.
Tenuta Campo di Sasso extends over about 56 hectares, where rows of vines perpendicular to the coast alternate with arable land and woodland. The terroir is predominantly sandy, and the microclimate is influenced by proximi- ty to the Tyrrhenian Sea: at Campo di Sasso, sea breezes blow constantly, reducing humidity and softening the hot summer temperatures in the vineyard, resulting in perfect grape ripening. In addition to Syrah—a historic variety for Campo di Sasso—Merlot, Sangiovese, and Petit Verdot are grown for red wines, and Vermentino for white wines. The wines of Campo di Sasso express the territory with elegance and immediacy.
