Petrolo

Petrolo

Petrolo is a historic Tuscan estate in the hills of Val d’Arno di Sopra, near Mercatale Valdarno in the municipality of Bucine, between Florence, Siena and Arezzo. Vineyards, olive groves and woodland form an interconnected landscape on the south-eastern side of the Chianti hills, overlooked by the medieval Torre di Galatrona.

Since the second half of the 1980s, Petrolo has progressively concentrated its wine production around individual vineyards and low yields, focusing on wines intended to express the character of the estate rather than maintaining a broad range of entry-level bottlings. Its vineyards encompass Sangiovese, Merlot, Cabernet Sauvignon and Trebbiano, with Galatrona establishing the estate's distinctive interpretation of Merlot.

History and Identity

Winegrowing at Petrolo belongs to a much older tradition in the Val d’Arno di Sopra. In 1716, Grand Duke Cosimo III de' Medici identified Val d'Arno di Sopra alongside Chianti, Carmignano and Pomino as one of Tuscany's areas recognised for the quality of its wine and olive oil.

During the nineteenth century, Petrolo was owned by agronomist Giorgio Perrin, who wrote in 1834 about Sangiovese and the character of the local terroir. The estate was acquired by the Bazzocchi family in the 1940s, beginning the family chapter that continues today.

A major transformation began during the second half of the 1980s. Petrolo moved progressively away from volume production towards increasingly selective viticulture and a smaller portfolio of vineyard-focused wines. The estate notes that vineyard density rose from around 1,500 plants per hectare in the 1950s to around 5,500, while overall wine production declined from approximately 3,500 hectolitres to fewer than 700.

This transition ultimately established the modern Petrolo identity: low yields, individual vineyards, careful grape selection and wines closely connected to their place of origin.

Estate, Vineyards and Terroir

Petrolo lies on the south-eastern edge of the Chianti hills, within the historic Val d’Arno di Sopra territory. Vineyards coexist with olive groves, oak woodland and other natural vegetation, creating a diverse agricultural landscape.

Rather than being defined by a single soil or grape variety, Petrolo comprises several distinctive vineyard sites.

Bòggina is the estate's historic Sangiovese vineyard, originally planted by Gastone Bazzocchi in 1947. It provides fruit for several expressions bearing the Bòggina name.

Galatrona is Petrolo's principal Merlot vineyard. Approximately 10 hectares in size and situated around 300 metres above sea level with a south-eastern exposure, it contains clay-rich soils combined with shale, marl and sandstone. The vineyard comprises the Galatrona, Feriale and Dottore parcels.

The estate also includes smaller sites such as Campo Lusso, planted to Cabernet Sauvignon on a natural terrace beneath the medieval Galatrona tower, together with vineyards including Campaccio, Campo Ai Diavoli, Casariccio, Lecceta, Meletana and Ospedale.

This mosaic allows Petrolo to work with several varieties while maintaining a strongly site-specific approach.

Viticulture

Petrolo began moving away from conventional farming practices in 2004, progressively adopting natural and sustainable vineyard management.

The estate practises dry farming, avoids fertilisation and tillage, maintains permanent grass cover managed through mulching and does not use synthetic pesticides. Vineyard work is largely manual and adapted to individual plants rather than applied uniformly across every parcel.

Petrolo obtained organic certification in 2016 for its wines, following a much longer history of organic cultivation in its olive groves.

The underlying philosophy is one of natural balance: vegetation, vines, olive trees and woodland are treated as components of the same agricultural ecosystem rather than isolated crops.

Production and Winemaking

Petrolo's cellar philosophy follows the same selective approach established in the vineyards.

Hand harvesting, rigorous grape selection and relatively low yields underpin production. For its major red crus, Petrolo uses native yeasts and seeks to allow the individual vineyard to determine the character of the finished wine rather than imposing a uniform cellar style.

Galatrona, for example, is fermented naturally with native yeasts in cement vats following manual harvesting and sorting. Bòggina A takes a distinctly different route, with Sangiovese fermented and matured in terracotta amphorae. Bòggina B, made from Trebbiano, is vinified and matured in French oak tonneaux.

These differences are important for the producer page: Petrolo does not employ one fixed winemaking recipe across its portfolio. Vessel, maturation and élevage depend on the vineyard and individual wine.

Exact maturation periods, oak proportions and other technical specifications should therefore remain on the relevant bottle and vintage pages.

Style and Identity

Petrolo's identity is based less on a single grape variety than on the relationship between individual vineyard sites and their varieties.

Sangiovese provides the historical Tuscan foundation through vineyards such as Bòggina. Merlot reaches its most concentrated expression in Galatrona. Cabernet Sauvignon is represented by the tiny Campo Lusso vineyard, while Trebbiano provides a white-wine dimension through Bòggina B.

Across these wines, Petrolo seeks concentration without losing balance, with an emphasis on terroir, freshness, structure and individual vineyard character.

For SCI, I would define Petrolo's producer DNA as:

Val d’Arno di Sopra → individual vineyards → low yields → organic farming → native yeasts → restrained intervention → terroir expression
