Storia
Roman antecedents
Tenuta Castiglioni extends along the ancient Via di Castiglioni, a road built by the Romans to connect northern Tuscany with Rome. The surrounding area was already known for the quality of its agricultural harvests, occupied a central position in intensive trade, and was selected for the construction of luxurious Roman villas.
From Val di Pesa to Florence
Around the year 1000, the earliest members of the Frescobaldi family moved from Val di Pesa to Florence. Tenuta Castiglioni remained the family's oldest agricultural property in its place of origin. The estate has belonged to the family since the 11th century.
The beginning of Frescobaldi winemaking
Documentary evidence traces wine production at Castiglioni to 1300. The estate is therefore regarded as the place where the Frescobaldi family's winemaking history began, inaugurating a tradition that has continued for approximately seven centuries.
During the 15th and 16th centuries, Frescobaldi wines reached European courts, including the Papal Court in Rome and the English court. Wine originating from the family's Tuscan production was appreciated in the 1500s at the Papal Court and at the court of Henry VIII.
The Frescobaldi coat of arms—comprising a crown, shield and three fortresses—also serves as a symbol of Castiglioni, commemorating the estate as the starting point of the family's seven-century wine history.
The Giramonte vineyard and Cru
The vineyard associated with Giramonte was planted in 1993. In 1999, Tenuta Castiglioni introduced Giramonte, described as the rarest and most exclusive Frescobaldi Cru. Its identity was tied to Merlot and Sangiovese, rigorous harvest selection, an individual microclimate and soils whose sandy and clay components reflect the area's marine geological past.
Renaming and contemporary stewardship
Before the 2009 vintage, the estate wine's label bore the name “Tenuta di Castiglioni.” From the 2009 vintage onward, it became “Tenuta Frescobaldi Castiglioni.”
In 2012, the Frescobaldi estates obtained the Region of Tuscany's AgriQualità certification for environmentally sustainable agricultural techniques. Today, the family's 30th generation continues to manage the wider enterprise with an emphasis on preserving the identity of each individual estate and its terroir.
Terroir
Location and landscape
Tenuta Castiglioni lies in the gentle hills of Val di Pesa, within the municipality of Montespertoli in Tuscany. Estate technical data place the vineyards between 200 and 250 metres above sea level, predominantly facing southwest.
Climate
The growing environment combines a mild climate with afternoon breezes arriving from the Tyrrhenian Sea. The interaction of climate, fresh soils and maritime air contributes to the structure and fruit expression sought in the estate's wines.
Clay is important during dry seasons because the subsoil can retain water accumulated during earlier rainfall. In the dry 2012 season, this retained moisture supplied freshness and strength to the vines. The 2017 season similarly demonstrated the water-holding capacity of the clay-rich soils, which helped moderate summer drought stress.
Soils and geological history
The estate encompasses varied soils with stony and clay formations. The broader vineyard profile has also been described as clay-limestone or clay-silt. Fresh clay-rich ground is associated with fruit expression.
The Giramonte sector has a more particular profile. Its soils combine sand and clay, reflecting land that lay beneath the sea several millennia ago. Historical technical descriptions distinguish alkaline clay soils rich in calcium and minerals from well-drained, neutral sandy soils containing evident rounded river stones. The current Giramonte profile describes loamy soil. This combination of soil, southwest exposure and an individual microclimate underpins the identity of the estate's Cru.
Vinificazione
The estate follows the integrated-production and sustainable-agriculture principles applied across the Frescobaldi estates. Since 2012, these practices have carried AgriQualità certification from the Region of Tuscany, a standard associated with ecologically sustainable farming compatible with protection of the natural environment.
Historical vineyard profiles record spur-pruned cordon training and densities of 5,500 vines/ha in the principal estate and Giramonte vineyards. Older Chianti profiles give a broader density range of 2,800–5,500 vines/ha.
Selection is especially exacting in the Giramonte vineyard. Merlot and Sangiovese are picked and selected by hand, with the rigorous selection intended to maintain consistency between harvests.
Vintage records illustrate the estate's response to seasonal conditions. Clay-rich soils retain winter and spring moisture and can moderate drought stress during hot, dry summers. Dry growing periods have reduced disease pressure, while cool nights and warm days near harvest have favoured gradual ripening and polyphenol development. Vineyard teams have also had to balance vegetative growth, fungal protection and fruit health during rainy seasons.
Production at Tenuta Castiglioni employs distinct cellar approaches according to vineyard and intended expression.
For the Cabernet Sauvignon, Merlot, Cabernet Franc and Sangiovese estate blend, freshly harvested grapes are destemmed and fermented in temperature-controlled stainless-steel tanks. Extraction is managed through light, regular pumping over. Malolactic fermentation follows alcoholic fermentation, after which the wine matures for 12 months in barriques and receives a further two months in bottle. Historical profiles record a 12-day maceration and malolactic fermentation immediately after alcoholic fermentation.
Giramonte is handled separately as the estate's Cru. Hand-selected Merlot and Sangiovese undergo spontaneous alcoholic fermentation in temperature-controlled stainless-steel vessels. Light pumping over is used, particularly during the opening days of fermentation. Malolactic fermentation takes place in new French-oak barriques, followed by maturation in the same vessels and additional bottle ageing. Historical vintages were macerated separately by variety for approximately 15–20 days and matured for 14–16 months in new barriques, depending on the vintage, with some releases receiving six months in bottle.
The Chianti DOCG process is centred on stainless steel. The current release matures for six months in steel vats, followed by a period in bottle. Earlier profiles specify an 11-day maceration, malolactic fermentation immediately after alcoholic fermentation, and six months in stainless steel with micro-oxygenation.
Filosofia
Castiglioni's identity rests on the relationship between individual terroirs and their wines. The estate aims to express the fruit and structure generated by its clay-rich soils, mild climate and Tyrrhenian afternoon breezes rather than impose a single style across the family's properties.
This principle is part of the wider Frescobaldi commitment to “cultivating Tuscan diversity”: each family estate and its vineyards should express its own natural character and authenticity. The family also presents its accumulated knowledge and traditions as an inheritance to be passed to future generations.
Giramonte embodies the balance between continuity and a contemporary approach. Its modern character is intended to remain faithful to Castiglioni's history and physical environment. An individual microclimate, marine-derived sandy and clay soils, and rigorous grape selection are treated as the basis for consistency from one harvest to the next.
Environmental responsibility is expressed through integrated production, sustainable agriculture and AgriQualità certification. Across the family estates, lighter bottles, reduced glass use, lower water and energy consumption, renewable electricity and lower transport-related emissions complement work in the vineyards.
