Aux Clous Premier Cru: A Complete Guide to Savigny-les-Beaune's Distinctive Climat
Overview & Location
Aux Clous stands as one of the most distinctive Premier Cru vineyards in Savigny-les-Beaune, occupying a strategic position within the northern sector of this renowned commune in Burgundy's Côte de Beaune. Located approximately 12 kilometers southwest of Beaune, this climat exemplifies the unique character that has made Savigny-les-Beaune one of the most respected appellations in the region.
The vineyard sits on the eastern slopes above the village of Savigny-les-Beaune, positioned between the more famous Premier Crus of Aux Vergelesses to the north and Les Lavières to the south. This placement puts Aux Clous in the heart of Savigny's premier vineyard sites, benefiting from the optimal exposition and geological conditions that define the commune's finest terroir.
Within the broader context of the Côte de Beaune, Aux Clous represents the transitional character between the power and structure found in the northern communes like Aloxe-Corton and the elegance and finesse typical of sites further south. This geographical positioning contributes significantly to the unique personality of wines produced from this climat, offering a harmonious balance that reflects both the mineral backbone of the northern Côte de Beaune and the refined character that defines the region's greatest expressions.
The climat's name, literally translating to "at the nails," likely derives from historical vineyard markers or boundary stones, a common etymology for Burgundian vineyard names that speaks to the ancient practice of precisely delineating these precious parcels of land.
Size
Aux Clous encompasses approximately 18.5 hectares (45.7 acres) of Premier Cru vineyard land, making it one of the moderately sized Premier Cru climats within Savigny-les-Beaune. This size places it in the middle range among the commune's 22 Premier Cru designations, larger than some of the most prestigious but smaller sites like Aux Vergelesses (9.5 hectares), yet more intimate than the expansive Les Lavières (34 hectares).
The vineyard's configuration consists of a relatively cohesive block of vines, though like most Burgundian climats, ownership is fragmented among multiple proprietors. This fragmentation, typical of the region's complex ownership patterns established through centuries of inheritance and division, means that the total surface is divided among approximately 15-20 different producers, with individual holdings ranging from small parcels of less than half a hectare to more substantial plots of 2-3 hectares held by some of the larger négociant houses and established domaines.
The relatively substantial size of Aux Clous, compared to some of Burgundy's most famous micro-climats, allows for a meaningful production volume while still maintaining the terroir specificity that defines Premier Cru quality. This scale provides wine enthusiasts with better availability than some of the region's most exclusive sites, while the quality remains uncompromisingly high due to the exceptional terroir characteristics.
Terroir & Geology
The geological foundation of Aux Clous reflects the complex sedimentary history of the Côte de Beaune, with soils that have evolved over millions of years to create the perfect medium for Pinot Noir cultivation. The underlying bedrock consists primarily of Jurassic limestone from the Bathonian period, dating back approximately 165 million years, which provides the essential mineral backbone that characterizes the finest Burgundian terroirs.
The soil composition is dominated by brown calcareous clay-limestone soils, with a notably higher proportion of clay content than many neighboring Premier Cru sites. This clay component, typically ranging from 35-45% depending on the specific location within the climat, provides excellent water retention capabilities while the limestone ensures proper drainage during periods of heavy rainfall. The limestone content, comprising roughly 40-50% of the soil matrix, contributes essential minerality and helps regulate vine nutrition, preventing excessive vigor while ensuring steady, even ripening.
The topsoil depth varies across the climat, generally measuring 60-90 centimeters before reaching the limestone mother rock. This relatively shallow soil profile forces vine roots to penetrate deep into the fractured limestone bedrock, accessing mineral-rich water sources and developing the complex root systems that contribute to the wine's distinctive mineral character and aging potential.
Aux Clous sits at elevations ranging from 280 to 320 meters above sea level, positioned on slopes that face primarily east-southeast, with some parcels enjoying pure eastern exposition. This orientation provides optimal sun exposure during the crucial morning hours while offering some protection from the harsh afternoon sun during the hottest summer days. The slope gradient varies from 5-12%, creating natural drainage while preventing excessive erosion.
The geological formation includes significant deposits of iron-rich oolitic limestone, which contributes a distinctive rust-colored tinge to certain soil sections and plays a crucial role in the wine's eventual color development and tannic structure. Fossil-rich limestone layers are evident throughout the climat, indicating the ancient marine environment that once covered this region and continues to influence the mineral complexity found in wines from this site.
Climate & Microclimate
The climatic conditions at Aux Clous reflect the classic continental climate of the Côte de Beaune, characterized by warm, dry summers and cold winters, with significant diurnal temperature variations that prove essential for maintaining acidity and developing complex aromatics in Pinot Noir. However, the specific microclimate of this climat creates unique conditions that distinguish it from surrounding sites.
The eastern and southeastern exposition ensures that the vineyard receives the beneficial morning sun, which helps dry dew quickly and reduces the risk of fungal diseases, while the gradual warming throughout the day promotes steady photosynthesis and sugar accumulation. The slope's orientation also provides natural protection from the prevailing westerly winds, creating a more sheltered environment that extends the growing season and allows for optimal phenolic development.
The elevation range of 280-320 meters places Aux Clous in the optimal altitude zone for Pinot Noir in this region, high enough to benefit from cooler nighttime temperatures that preserve acidity and aromatic complexity, yet low enough to ensure adequate heat accumulation for proper ripening in most vintages. This elevation creates a mesoclimate that typically experiences temperatures 1-2°C cooler than the valley floor, extending the growing season by 7-10 days compared to lower-elevation sites.
The limestone bedrock and well-drained soils create a microclimate that responds quickly to weather changes, warming rapidly in spring to encourage early bud break, yet providing thermal regulation during hot summer periods through the cooling effect of underground water circulation through the fractured limestone. This natural temperature regulation helps maintain the delicate balance between ripeness and freshness that defines great Burgundy.
Rainfall patterns are generally well-suited to viticulture, with most precipitation occurring during winter and spring months, though the changing climate patterns have created increased variability in recent decades. The slope orientation and soil drainage characteristics help manage excess water effectively, preventing vine stress during wet periods while the limestone subsoil provides access to deep water reserves during drought conditions.
Viticulture
Aux Clous is planted exclusively to Pinot Noir, as are all Premier Cru sites in Savigny-les-Beaune, reflecting the commune's specialization in red wine production. The vineyard's viticultural practices have evolved significantly over recent decades, with most quality-conscious producers adopting sustainable or organic approaches that emphasize terroir expression over high yields.
The average vine age across the climat varies considerably among different proprietors, ranging from recently replanted sections of 10-15 years to venerable old-vine parcels that are 50-80 years old. Many of the most respected producers maintain vine ages of 35-45 years on average, representing the optimal balance between established root systems that access deep terroir characteristics and vines that retain sufficient vigor for consistent production.
Planting density typically ranges from 10,000 to 12,500 vines per hectare, following traditional Burgundian practices that encourage competition among vines and limit individual vine production. This high density planting, combined with careful pruning to restrict yields, ensures that each vine produces a small quantity of highly concentrated fruit that faithfully reflects the terroir characteristics.
Most producers employ the Guyot pruning system, either simple or double depending on vine vigor and terroir characteristics, with careful attention to maintaining appropriate shoot positioning and canopy management. The clay component in the soil requires particular attention to vigor management, as excessive vegetative growth can easily occur in wet years, necessitating careful green harvesting and leaf removal to maintain proper grape exposure and air circulation.
Harvest timing at Aux Clous typically occurs in mid to late September, though climate change has gradually moved average harvest dates earlier over the past two decades. The varied exposition and elevation within the climat means that different parcels may ripen at slightly different rates, allowing experienced producers to harvest each section at optimal maturity.
Site-specific viticultural challenges include managing the vigor that can result from the clay-rich soils, particularly in wet vintages, and ensuring adequate drainage in the lower sections of the vineyard where clay content is highest. Many producers have invested in improved drainage systems and employ cover crops to help regulate soil moisture and vine nutrition naturally.
Wine Character & Style
Wines from Aux Clous exhibit a distinctive style that combines the structural backbone typical of northern Côte de Beaune sites with an elegant mineral complexity that sets them apart from many neighboring Premier Crus. The higher clay content in the terroir contributes to wines that show more body and textural richness than some of the limestone-dominated sites, while the eastern exposition preserves the freshness and aromatic intensity that defines great Burgundy.
The aromatic profile typically features classic red fruit characteristics, with cherry and raspberry predominating in younger wines, evolving toward more complex notes of blackberry, plum, and dried herbs with age. The limestone influence is evident in the mineral undertones that provide a distinctive "chalk dust" character, while the iron-rich soil components contribute subtle earthy notes and spice complexity that becomes more pronounced with bottle age.
Structurally, Aux Clous produces wines with medium to medium-full body, supported by firm but refined tannins that reflect both the terroir's mineral composition and careful winemaking approaches. The acidity is typically well-integrated and persistent, providing the backbone necessary for extended aging while maintaining freshness and food compatibility. The texture often shows a distinctive silky quality in the mid-palate, attributed to the clay influence, followed by a mineral-driven finish that can extend for 30-40 seconds in the finest examples.
Color intensity varies depending on vine age and vintage conditions, but typically shows good concentration with a bright ruby-red hue that develops amber highlights with age. The wines generally show excellent clarity and luminosity, reflecting the well-drained terroir and careful viticulture practices employed by quality-focused producers.
The flavor development follows a classic Burgundian trajectory, with primary fruit characteristics dominating in the first 2-3 years, followed by the emergence of more complex secondary flavors including forest floor, mushroom, and dried flower notes. The tertiary development phase, typically beginning after 7-10 years, reveals the full terroir character with distinctive mineral elements, leather, game, and exotic spice notes that can continue evolving for decades in the finest vintages.
Comparison to Surrounding Crus
Within the context of Savigny-les-Beaune's Premier Cru hierarchy, Aux Clous occupies a distinctive position that differentiates it from its immediate neighbors through both terroir characteristics and resulting wine style. Compared to the prestigious Aux Vergelesses, located immediately to the north, Aux Clous produces wines with more immediate approachability and rounder texture, though perhaps with slightly less aging potential and mineral intensity.
The contrast with Les Lavières, the large Premier Cru to the south, is particularly instructive. While Les Lavières tends to produce wines with more delicate structure and floral characteristics due to its different exposition and soil composition, Aux Clous offers greater body and textural complexity, making it more suitable for extended aging and pairing with richer dishes.
Compared to Les Narbantons, another neighboring Premier Cru, Aux Clous generally shows more consistent quality across different producers, likely due to its more uniform terroir characteristics and optimal exposition.

Historical Background & Classification
The viticultural history of Aux Clous extends back to the medieval period, when Cistercian monks from nearby religious institutions first recognized the exceptional potential of these eastern-facing slopes. Historical documents from the 12th and 13th centuries reference vineyard parcels in locations corresponding to modern-day Aux Clous, indicating that the site's reputation for producing superior wines has been established for nearly eight centuries.
The climat's formal recognition as Premier Cru status came with the establishment of Burgundy's modern appellation system in 1936, when the Institut National des Appellations d'Origine (INAO) codified the classification system that had evolved organically over centuries of viticulture. However, the site's reputation for producing wines of superior quality was already well-established long before official classification.
Throughout the 18th and 19th centuries, wines from Aux Clous were frequently mentioned in historical records and wine merchant correspondences as examples of Savigny-les-Beaune's finest expressions. The climat weathered the phylloxera crisis of the late 19th century, with replanting on American rootstock completed by the early 1900s, maintaining the continuity of winemaking tradition that defines the site today.
The modern era has seen significant improvements in viticultural practices and winemaking technology, while maintaining respect for traditional methods that have proven successful over centuries. The classification as Premier Cru has been reaffirmed through successive revisions of appellation laws, most recently with the comprehensive review completed in the 1990s that solidified the boundaries and quality requirements for all Burgundian Premier Cru sites.
Aging Potential & Quality Level
Aux Clous produces wines with excellent aging potential that typically follows a predictable evolution trajectory, though this varies significantly based on vintage conditions, producer style, and storage conditions. In general, wines from this climat show optimal drinking windows beginning around 5-7 years after vintage, with the finest examples continuing to develop complexity for 15-20 years or more in exceptional vintages.
The initial aging phase, covering the first 2-4 years, sees the integration of tannins and the softening of initial fruit intensity, while the mineral characteristics begin to emerge more prominently. During this period, the wines often go through a somewhat closed phase where the primary fruit recedes before secondary complexity develops.
The prime drinking period typically extends from years 6-12, when the terroir characteristics are most clearly expressed and the balance between fruit, earth, and mineral elements reaches optimal harmony. During this phase, the wines show their most complete expression of the Aux Clous terroir, with fully integrated structure and maximum aromatic complexity.
Extended aging potential varies considerably based on vintage quality and producer methods, but the finest examples can continue evolving positively for 20-25 years. The limestone-rich terroir provides the mineral backbone necessary for extended aging, while the clay component ensures sufficient body and extract to support long-term development.
Quality consistency across vintages is generally high for Aux Clous, with the terroir characteristics providing some protection against challenging weather conditions. Even in difficult vintages, competent producers typically achieve wines that express the site's personality, though with varying levels of concentration and aging potential.
The climate change impacts of recent decades have generally been positive for Aux Clous, with more consistent ripening and fewer years of insufficient maturity. However, this has also meant that producers must adapt their techniques to manage higher alcohol levels and maintain the freshness that defines great Burgundy.
Investment potential for wines from Aux Clous remains strong, particularly from established producers with track records of quality and consistency. While not reaching the price levels of Grand Cru sites, the combination of limited production, increasing recognition, and excellent aging potential makes these wines attractive for both drinking and collecting purposes.
