Castelgiocondo is a Tuscan wine estate owned by the Frescobaldi family, known for its Sangiovese wines from the Brunello di Montalcino appellation. The estate buildings, which overlook the village of the same name, were built around AD1100 as a stronghold on the road from the port of Talamane to Siena. It was one of the first estates in the region to produce wine, starting in the early 19th Century.

Vineyards of the estate are located between 300 and 400 meters (1000 to 1300 feet) above sea level. This altitude combined with the location of southwest-facing slopes and well-drained soils creates ideal terroir. The flagship wine of the Castelgiocondo portfolio is the Ripe al Convento riserva Brunello. In the single vineyard from where the Ripe al Convento is sourced, grapes are hand-picked to preserve the varietal characteristics. After vinification, it spends up to six years aging in the cellar in oak as well as in bottle prior to release.

"On the highest hills of this estate, which began producing wine in the year 1800, a small Sangiovese vineyard amazes us with extraordinary emotions. At an altitude of 450 metres, the vineyard benefits from warm sun in the afternoon, galestro-type soil, and fresh Mediterranean breezes producing a uniquely elegant Brunello Riserva, with personality and longevity" Lamberto Frescobaldi. Brunello di Montalcino is one of Italy's most famous and prestigious wines. In Tuscany, its homeland, it perhaps ranks alongside Chianti Classico. The wine is typically garnet in colour with aromas of red and black fruit with underlying vanilla and spice, and perhaps a hint of earthiness. The wines are usually full-bodied with alcohol levels around 14 or 15 percent abv. Good tannic structure and bright acidity provide balance.

All Brunello di Montalcino wine is made exclusively from Sangiovese Grosso grapes grown on the slopes around Montalcino – a classic Tuscan hilltop village 30 kilometres (20 miles) south of Siena. Sangiovese Grosso is the large-berried form of Sangiovese. Its name here translates roughly as 'little dark one'. The use of this synonym and its inclusion in the name of the wine was part of a clear strategy to differentiate the wine from Chianti.
