Marchesi Antinori is an Italian wine company that can trace its history back to 1385. They are one of the biggest wine companies in Italy, and their innovations played a large part in the "Super-Tuscan" revolution of the 1970s. Antinori is a member of the Primum Familiae Vini and the 10th oldest family owned company in the world.

Estates:

• Tignanello - is a 47 hectare vineyard acquired in 1900 and gives its name to Antinori's most famous wine, designated a Vino da Tavola since the mid-1970s and IGT Toscana since the early 1990s. Since 1982, Tignanello has been made from 85% Sangiovese, 10% Cabernet Sauvignon and 5% Cabernet Franc. The vineyard lies at 1150–1312 feet above sea level, within the Santa Cristina estate (also known as Tenuta Tignanello).
• Solaia - 'The sunny one' is a 10 hectare vineyard adjacent to Tignanello in the Mercatale Val di Pesa zone of Chianti Classico. The eponymous wine was released in 1978 as an 80% Cabernet Sauvignon, 20% Cabernet Franc blend, although that has now evolved to a mix of 75% Cabernet Sauvignon, 5% Cabernet Franc, 20% Sangiovese. Like Tignanello, fruit not used for the grand vin goes into Antinori's Chianti Classico Riserva, Tenute del Marchese and the IGT Villa Antinori (60% Sangiovese, 20% Cabernet Sauvignon, 15% Merlot and 5% Syrah).
• Pèppoli Estate - Close to Tignanello, 55ha of the 100ha of the Peppoli estate are planted with vines. The slopes face northeast, but the unique microclimate of the valley produces a fruity Pèppoli Chianti Classico and contributes to Marchese Antinori.
• Badia a Passignano - The Antinoris bought the 325 hectare estate around the historic Vallombrosian abbey in 1987, including the right to use the abbey's cellars. Fifty hectares are planted with Sangiovese from Tignanello which provides the grapes for another Chianti Classico DOCG Riserva, Badia a Passignano. Piero Antinori regards this as his testbed for the ultimate expression of Sangiovese in Tuscany. Some grapes go into Marchese Antinori.
• Guado al Tasso - A massive estate of 900 hectares in the Bolgheri bowl, 60 miles SW of Florence, at just 150–200 feet above sea level. A third of it is planted with vines, mostly Sangiovese, Cabernet, Merlot and Syrah, grapes here ripen two weeks before the Chianti holdings. The best known wines are Guado al Tasso, the Scalabrone rose, Il Bruciato and Vermentino. Matarocchio is a lesser-known and rarer expression of 100% Cabernet Franc.
• La Braccesca estate - Vino Nobile di Montepulciano La Braccesca, Vigneto Santa Pia, Sabazio, and the Bramasole and Achelo Syrahs.
• Pian delle Vigne Estate - Sixty hectares of vineyard in a 186 hectare estate bought in 1995, which provides their Brunello di Montalcino.
• Fattoria Aldobrandesca - Aleatico comes from this Etruscan vineyard near Sovana in Southern Tuscany.
• Monteloro Estate - North of Florence, supplies the white wines Villa Antinori Bianco and Capsula Viola.
• Castello della Sala - 500 hectare estate with 160 hectares of vineyard producing Orvieto Classico, Campogrande and Casasole, a Pinot Nero, the Chardonnay-based Cervaro della Sala, and the Sauvignon Blanc-based sweet Muffato della Sala.
• Antica Napa Valley - Antinori's wine estate in Napa, California. Produces Cabernet Sauvignon, Chardonnay, Sangiovese, Sauvignon Blanc, Pinot Noir, and Cabernet Franc on 600 planted acres in Atlas Peak AVA.
