In the geographical and spiritual heart of the Chianti Classico denomination, nestled between Florence and Siena, lies a viticultural enclave of singular importance: Panzano. More than just a subzone, Panzano has established itself as a cru of category mundial, a terroir defined by a fundamental and productive tension. It is, simultaneously, the epicenter of Sangiovese purism and a historic cradle of the Super Tuscan international blend. This duality is not a contradiction, but a testament to the power and versatility of its land—a place where grape varieties, whether native or foreign, are compelled to express their deepest character.

The viticultural epicenter of Panzano is the “Conca d’Oro” (the Golden Basin), a natural, south-facing amphitheater that captures sunlight with exceptional intensity. This landscape, a basin of gently rolling hills, creates a unique microclimate, characterized by a combination of high altitude, superior luminosity, and a marked diurnal temperature variation between day and night. These conditions are crucial for developing superior aromatic complexity and retaining vibrant acidity, the hallmarks of great age-worthy wines.

The foundation of this unique expression is a geological trinity. Panzano’s soils are a mosaic of three principal types that define the signature of its wines. Galestro, a friable, schistous clay, provides elegance, minerality, and a refined tannic structure. Alberese, a hard, calcareous marl, imparts power, body, and longevity. And pietraforte, a less frequent, calcareous sandstone, lends a muscular character and robust structure. This geological diversity is the canvas upon which each grape variety paints its particular portrait.

This singular identity has been championed and promoted by the Unione Viticoltori di Panzano, an association of 22 producers who have forged a collective path. Their most notable achievement is a near-universal commitment to certified organic and biodynamic viticulture, making Panzano the “Organic Heart of Chianti Classico”. This collective action is not a mere marketing detail; it is a foundational principle that underpins the purity and transparency of the area’s wines.

Recently, this distinction has been formally codified with the designation of Panzano as an Unità Geografica Aggiuntiva (UGA). This official recognition within the Chianti Classico denomination validates what connoisseurs have known for decades: that Panzano is a place with an indelible identity, a terroir capable of producing world-class wines from a surprisingly diverse spectrum of grapes. This report delves into the heart of that identity, exploring each grape variety that has found a home in the Conca d’Oro.

The story of Panzano is one I felt compelled to tell in full. If this article has sparked your curiosity, I invite you to continue the discovery. My book, Toscana’s Organic Wines: Panzano in Chianti, is the comprehensive account of my dive into the land, the people, and the philosophy that make this place so special.

Part I: The tuscan soul – indigenous varieties

1. Sangiovese: the sovereign of the golden basin

The global benchmark

Sangiovese is Italy’s most planted grape variety, the soul of Central Italian viticulture. Its classic sensory profile is defined by vibrant acidity and firm tannins framing a core of sour red cherry fruit, often complemented by earthy, tea leaf, and leather notes. Though adaptable, Sangiovese reaches its peak expression in soils with a high concentration of limestone, like the

galestro and alberese of Tuscany, where it can produce elegant wines with powerful aromas. Its noblest manifestations, Brunello di Montalcino and Vino Nobile di Montepulciano, serve as global benchmarks for their structure, complexity, and extraordinary ability to age, often requiring years of cellaring to reveal their true character.

The Panzano expression: power and elegance

In Panzano, Sangiovese transcends its classic profile to forge a singular identity, marked by a combination of power and elegance that is unique to this terroir. The symbiosis of galestro and alberese soils is fundamental; it provides a robust tannic structure and a mineral backbone while naturally limiting the vine’s vigor, leading to greater fruit concentration. The high altitude of the vineyards and the significant daily temperature swings are equally crucial. The cool nights preserve bright acidity and allow for a slow, complete ripening cycle, developing an intense and complex aromatic palette that goes beyond simple fruit to encompass floral, spicy, and balsamic notes. The result is a Sangiovese with a deeper color, fruit that veers towards black cherry and plum, and a structure that promises exceptional longevity.

Producer case study: Fontodi and Sangiovese purism

The Fontodi estate, under the direction of Giovanni Manetti, is the archetype of Sangiovese purism in Panzano. Manetti’s philosophy, as the current president of the Chianti Classico Consorzio, has been a staunch defense of Sangiovese’s integrity, systematically prioritizing it over international varieties. This conviction is embodied in the estate’s iconic wines.

Flaccianello della Pieve, which began as a blend, has been made from 100% Sangiovese since the 1981 vintage. Similarly, the Vigna del Sorbo, formerly a Chianti Classico Riserva with a small percentage of Cabernet Sauvignon, became a 100% Sangiovese Gran Selezione starting with the 2012 vintage. For Manetti, Sangiovese alone is capable of revealing the fullest expression of the Tuscan terroir. This quest for purity extends to the cellar, where his family’s historic connection to terracotta production has inspired a pioneering use of amphorae for vinification and aging, a method that seeks to preserve freshness and the most transparent expression of the terroir without the influence of wood.

Producer case study: Le Cinciole and elegant authenticity

If Fontodi represents the power and structure of Panzano’s Sangiovese, Podere Le Cinciole, run by Valeria and Luca Orsini, embodies its more elegant and authentic side. Their Chianti Classico, made almost entirely from Sangiovese (often 98% or more), is a benchmark for floral and fruit purity. Critics consistently praise its energy, finely structured tannins, and decidedly red-fruited character, such as redcurrant and raspberry. Le Cinciole’s philosophy centers on minimal intervention and preserving the grape’s inherent freshness. This is reflected in their winemaking approach, which often employs a combination of cement vats and large oak casks for fermentation and aging. This method avoids the dominance of new wood flavors, allowing the charm and minerality of Panzano’s Sangiovese to shine through with clarity and precision.

2. The indigenous retinue: Canaiolo, Colorino, and Malvasia Nera

A world apart: the historical role

For centuries, Sangiovese rarely stood alone. It was accompanied by a retinue of indigenous varieties that performed specific functions in the traditional Chianti blend. Canaiolo, in fact, was the dominant variety in the region until the 19th century. It was prized for its ability to soften the sometimes-astringent tannins of Sangiovese and for its resistance to rot, which made it ideal for the governo technique—a process of refermentation with partially dried grapes that added body and stability to the wine. Colorino, true to its name, was used primarily as a coloring agent, contributing a deep ruby hue and additional phenolic structure from its thick skins. Malvasia Nera, meanwhile, brought aromatic complexity and a touch of softness.

A renaissance in Panzano

With the rise of 100% Sangiovese wines and the introduction of international varieties, these traditional grapes were relegated to the background. In Panzano, however, a group of forward-thinking producers is leading a renaissance, re-evaluating these varieties not as mere corrective additives but as integral components that bring complexity and a deeper sense of place. This resurgence is bolstered by the new regulations of the denomination, which are redefining the future of the region’s top-tier wines.

Producer case study: Candialle and co-fermentation

The Candialle estate, run by Jarkko Peränen and Josephin Cramer, is a prime example of this modern approach. Their Chianti Classico “La Misse” is a Sangiovese-led blend, but its distinctive character is partly due to the co-fermentation of small amounts of Canaiolo and Malvasia Nera. Instead of vinifying each variety separately and blending later, the grapes are harvested and fermented together. This traditional method seeks to achieve a more harmonious integration of flavors and aromas, adding layers of floral and spicy nuance that complement the Sangiovese fruit, creating a wine that is both energetic and complex.

Producer case study: Monte Bernardi and the traditional palette

Michael Schmelzer of Monte Bernardi also demonstrates a deep commitment to the full palette of traditional Tuscan varieties. His Chianti Classico Riserva includes 5% Canaiolo Nero from 40-year-old vines, using this grape to bring balance and finesse. In other wines, like the “Tzingarella”, he even incorporates 5% Colorino alongside Bordeaux varieties, demonstrating how a native grape can add a Tuscan touch of color and structure to an internationally inspired blend. This thoughtful use of indigenous varieties underscores a philosophy that values tradition as a tool for achieving a more authentic expression of the terroir.

Part II: The internationalists – a revolution in Panzano

The history of Panzano is inextricably linked to Sangiovese, but its modern reputation has been forged as much in rebellion as in tradition. The arrival of international varieties was not simply a trend, but a profound re-evaluation of the terroir’s potential. This revolution, however, now faces a new regulatory context that is redefining what it means to be an elite Chianti Classico wine.

The regulations of the Chianti Classico DOCG denomination are in constant evolution, and a recent change has profound implications for Panzano’s producers. The new rules for the highest category, “Gran Selezione,” require a minimum of 90% Sangiovese and stipulate that the 10% remainder can only be composed of other indigenous red varieties. International grapes like Cabernet Sauvignon, Merlot, and Syrah are explicitly excluded from this prestigious category.

This regulatory shift creates a fork in the road to excellence in Panzano. Historically, some of the most acclaimed and expensive wines from the area, like Castello dei Rampolla’s Sammarco, were pioneering Super Tuscans based on international blends. Under the new rules, these wines, no matter how profound or expressive of Panzano’s terroir, can never reach the top of the DOCG quality pyramid. This forces a strategic divergence. On one hand, the denomination is purifying its identity around Sangiovese and its native companions, incentivizing producers like Fontodi to push their Vigna del Sorbo Gran Selezione to new heights. On the other hand, this same regulation solidifies the importance of the IGT Toscana designation as the banner for the great international blends of Panzano. Far from being a lesser category, the IGT becomes the necessary haven for the wines that defined the Super Tuscan revolution in this area. Therefore, the Panzano landscape solidifies around a dual identity: a path of excellence within the DOCG, focused on the purity of Sangiovese, and a parallel path of excellence under the IGT, which continues the legacy of innovation with international varieties.

1. The Bordeaux blend in Chianti Classico: Cabernet Sauvignon, Merlot, Petit Verdot

The global benchmark

The Bordeaux blend is the most copied red wine paradigm in the world. Its success is based on the synergy of its components: Cabernet Sauvignon provides the structure, firm tannins, notes of blackcurrant and cedar, and aging potential. Merlot, on the other hand, offers fleshiness, a plush texture, and ripe plum flavors, making the wine more approachable in its youth. This interplay defines the styles of Bordeaux’s Left Bank, dominated by Cabernet, and the Right Bank, led by Merlot.

The genesis of the Super Tuscan in Panzano

While the story of the Super Tuscan often centers on the coast of Bolgheri, with wines like Sassicaia, Panzano has its own and distinctive narrative of the Bordeaux revolution. Here, in the heart of Sangiovese territory, the decision to plant French varieties was an act of audacity and vision.

Producer case study: Castello dei Rampolla, the protagonist

Castello dei Rampolla is the undisputed protagonist of this story. In the 1970s, in a region devoted almost exclusively to Sangiovese, Alceo di Napoli Rampolla had the bold intuition to plant Cabernet Sauvignon. His vision was guided by the legendary enologist Giacomo Tachis, often called the “father of the Super Tuscans,” who was also instrumental in the development of Sassicaia and Tignanello.³ This collaboration gave rise to wines that redefined Panzano’s potential.

The estate’s iconic wines are a testament to this revolution:

• Sammarco: Launched in 1980, it was a pioneering blend of Cabernet Sauvignon with Sangiovese and Merlot. Over the decades, it has maintained a cult status, praised for its ability to express an unmistakably Tuscan character despite its French grapes. Critics highlight its notes of black fruits, Mediterranean herbs, and a mineral structure that speaks more of Panzano than of Bordeaux.
• d’Alceo: This wine, a blend of Cabernet Sauvignon and Petit Verdot, represents the vision of the next generation, Luca and Maurizia di Napoli. It is described as a wine of immense intensity, warmth, and refinement, with complex notes of ripe red fruits, cigar box, and tobacco, demonstrating the extraordinary aging potential of Bordeaux varieties in the soils of the Conca d’Oro.

Widespread adoption

Rampolla’s audacity was not an isolated phenomenon but inspired other Panzano producers to explore the potential of international varieties. Candialle produces Ciclope, a blend of Merlot, Petit Verdot, and Cabernet Franc, and Pli, a Gran Selezione (from vintages before the new rules) that mixes Sangiovese with a touch of Petit Verdot. Monte Bernardi produces Tzingana, a classic Bordeaux blend of Merlot, Cabernet Sauvignon, Cabernet Franc, and Petit Verdot, and Tzingarella, a more accessible version. Le Cinciole also contributes with Camalaione, a powerful IGT based on Cabernet Sauvignon, Merlot, and Syrah. Together, these wines form a tapestry that proves Panzano’s terroir is as eloquent with the grapes of Bordeaux as it is with Sangiovese.

2. Transplants from the Rhône and Burgundy: Syrah and Pinot Nero

The global benchmark

Beyond Bordeaux, two of France’s most noble red varieties have also found an experimental home in Panzano. Syrah, in its Northern Rhône cradle, is famous for its structured, aromatic wines with characteristic notes of black pepper, olive, violets, and smoky black fruits. Pinot Nero (Pinot Noir), the soul of Burgundy, is revered for its elegance, delicate red fruit aromas, and unparalleled ability to transmit the subtleties of terroir.

Panzano’s terroir as interpreter

Panzano’s ability to reinterpret these French classics is definitive proof of its status as a great terroir. The sunny yet altitude-tempered climate and complex soils allow these varieties to ripen fully without losing their identity.

• Fontodi’s Pinot Nero: Giovanni Manetti’s decision to plant Pinot Nero in his Case Via vineyard was an act of faith in his land’s versatility. The result is a wine that defies expectations. Fermented in wooden vats and aged in Troncais oak barrels, Fontodi’s Pinot Nero shows a depth and a structure that are rarely found outside of Burgundy, demonstrating that with meticulous site selection, this delicate grape can thrive in the heart of Tuscany.⁷
• Le Cinciole’s Syrah: The inclusion of 15% Syrah in their IGT Camalaione, alongside Cabernet Sauvignon and Merlot, is an intriguing winemaking decision. Instead of creating a purely Bordelais wine, Le Cinciole introduces a Rhône element. The Syrah brings a spicy complexity, notes of pepper, and a dark, juicy fruit character that adds a new dimension to the blend, all filtered through the prism of Tuscan sun and soil.

Part III: The foundations – viticulture and vinification in Panzano

The expression of a grape variety in a wine depends not only on soil and climate but also on the human decisions made in the vineyard and the cellar. In Panzano, elite producers are adopting viticultural and enological practices that demonstrate a deep, nuanced understanding of their environment. Far from being mere technical choices, these decisions reveal a shared philosophy that seeks purity, sustainability, and the ultimate expression of terroir.

Viticulture as response to climate and return to tradition

One of the most revealing practices in Panzano is the re-adoption of an ancient and nearly forgotten training system. At the Candialle estate, a significant portion of the vineyards is planted at very high densities and trained in the alberello (bush vine) system. This method, which was the standard in Chianti Classico before modernization, is a rarity today due to its labor-intensive nature and the impossibility of mechanization.

The decision by Jarkko and Josephin Peränen to return to alberello is not an act of nostalgia but a highly intelligent and forward-thinking viticultural strategy. Research on this training system reveals its advantages in hot, dry climates. The bush-like structure creates a canopy that shades the clusters from direct sun, preventing over-ripening or “sunburn” of the grapes. Having no support wires encourages the roots to grow deeper into the soil in search of water, increasing the plant’s resistance to drought. Furthermore, the pruning system naturally limits the yield per vine, resulting in higher quality, more concentrated grapes.

By connecting these general principles to the specific context of Panzano, a powerful conclusion emerges. Candialle’s adoption of alberello is a proactive adaptation to climate change, a concern explicitly mentioned by other producers in the area like Giovanni Manetti. It is a method for obtaining the highest quality and terroir expression from the delicate Sangiovese, even in increasingly warm vintages. This is a case of “back to the future”: an ancient technique is being reclaimed as one of the most sophisticated tools to meet the challenges of modern viticulture and the quest for ultimate quality.

The “vessel renaissance” and the quest for terroir purity

Parallel to the innovations in the vineyard, a quiet revolution is taking place in Panzano’s cellars. Beyond the standard use of stainless steel tanks and French oak barriques, elite producers are employing a striking variety of fermentation and aging vessels. There is a sophisticated and deliberate use of concrete (Le Cinciole, Rampolla, Candialle), terracotta amphorae (Fontodi, Rampolla), cocciopesto—a Roman material made from crushed brick—(Rampolla), and ceramic orbs like Clayver (Candialle).

This phenomenon represents a fundamental philosophical shift. The first wave of the Super Tuscan revolution was often associated with the influence of new French oak barriques, a style that, while producing impressive wines, could sometimes mask the terroir under a veneer of international oak. The widespread adoption of these alternative, neutral vessels indicates a deliberate move in the opposite direction. Materials like terracotta, concrete, and ceramic allow for gentle micro-oxygenation, which helps soften tannins and stabilize the wine, but they impart no flavor of their own.

This is a conscious choice to move away from the winemaker’s imprint and toward a purer expression of the grape and, most importantly, of the Panzano terroir. It demonstrates a supreme confidence in the quality of the fruit being harvested. The goal is no longer to make a “Bordeaux-style” wine in Tuscany, but to make a wine from Panzano, even if the grape is Cabernet Sauvignon. Castello dei Rampolla’s “Sangiovese di Santa Lucia,” vinified entirely in terracotta and with no added sulfites, is the purest example of this philosophy. This “Vessel Renaissance” symbolizes the maturity of Panzano’s wine scene. It is a postmodern movement where producers use both ancient tools (terracotta) and modern innovations (Clayver) to achieve the ultimate goal of transparency. The character of the wine is now defined more by the soil it grew in (galestro, pietraforte) than by the barrel it aged in.

Conclusion: a viticultural mosaic

Panzano in Chianti has cemented its global status not through a monolithic identity, but by embracing a complex and multifaceted personality. It is a terroir of powerful dualities, a place where Sangiovese purism coexists in harmony with the innovation of international blends. It is a landscape where a deep respect for tradition, manifested in the revival of ancestral practices like the alberello training system, meets cutting-edge technology, such as the use of Clayver ceramic orbs for aging.

The foundation of this expressive diversity is a unifying collective ethos: a near-total commitment to organic and biodynamic viticulture that ensures the health of the soil and the purity of the fruit. Upon this shared foundation, each producer crafts their own interpretation of the terroir, whether through the single-varietal purity of Sangiovese, the complexity of indigenous blends, or the audacity of international varieties.

Ultimately, the grapes of Panzano, whether native to Tuscany or transplanted from France, are translated through the powerful prism of the Conca d’Oro. The intense sun, the cool nights, and the soils of galestro, alberese, and pietraforte leave an indelible mark on every berry. The resulting wines are not mere expressions of a variety; they are liquid portraits of this singular place. They are the product of a potent combination of sun, soil, and the vision of the vintners who have chosen to call this place their home, creating a viticultural mosaic of extraordinary depth and quality.
