Introduction
Carignano is Sardinia’s third most planted red grape variety and perhaps the one whose reputation has risen most dramatically over the last few decades. Indeed, few grape varieties have experienced a rehabilitation as remarkable as Carignano.
For decades, Carignano (known as Carignan in France, Mazuelo in Spain and with many other names around the world) was considered little more than a productive workhorse, capable of delivering large yields but rarely associated with fine wine. As viticulture evolved and quality became the focus, the variety often found itself uprooted in favour of more fashionable alternatives.
Nowhere is this more evident than in Sulcis, in south-west Sardinia, where some of the world’s most distinctive Carignano wines are produced from ancient, ungrafted bush vines growing in sandy coastal soils.
However, Sardinia is not alone. Southern France, north-eastern Spain, and Chile have all developed their own interpretations of the variety. Today, old-vine Carignano around the world is enjoying a renaissance. Producers across the Mediterranean and beyond have rediscovered its ability to produce wines of remarkable freshness, complexity, longevity, and terroir expression.
Therefore, in this blogpost I will explore Carignano/Carignan/Mazuelo’s different expressions in Sardinia, Spain, France and Chile. Four wine regions where this grape variety is widely planted and where different climate, soils, altitude, vineyard practices and winemaking traditions contribute to shaping different wines, despite their common roots.
In this sense, Carignano represents Sardinia’s distinctive interpretation of one of the Mediterranean’s most important grape varieties — a wine style that is both part of a global family and deeply rooted in the island’s landscape.
No discussion about comparing wines would be complete without a tasting, so I will accompany this theoretical discussion with a comparative tasting of four wines from these regions in a subsequent blogpost.
In a past blogpost, I sketched the main features of Carignano in Sardinia, also touching upon its origins. While the precise origins of Carignano remain debated, most ampelographers agree that the variety likely originated in north-eastern Spain, in the region of Aragón, where it is traditionally known as Mazuelo or Cariñena. The variety appears to be closely linked to the town of Cariñena, from which it likely takes its name—Carignan in French and Carignano in Italian. From Spain, the grape spread throughout the western Mediterranean, becoming particularly successful in Sardinia and southern France (and, formerly, in French Algeria).
Historically, Carignano’s reputation was mostly that of a workhorse variety because of its naturally high vigour and productivity. When yields were excessive, wines could be rustic, diluted, and excessively tannic.
The modern renaissance of the variety is therefore largely linked to two factors: the preservation of old vines, naturally limiting yields; and more precise viticulture and winemaking practices. Today, some of the most exciting examples of Carignano come from vineyards planted many decades ago, often in challenging environments where yields remain naturally low.
Although historically centred in the western Mediterranean, Carignan has now spread across several continents. France is the country hosting by far the most plantings (53,155 ha), with nearly 80% of the plantings concentrated in Languedoc-Roussillon. Spain comes as a distant second (6,130 ha), with most plantings in Catalunya (where the variety is also known as Samsó), Rioja, Aragón and Castilla-La Mancha. Italy comes third, with almost all the plantings (97%) in Sardinia (2,000 ha) and a very small portion in other regions. In the new world, most Carignan’s plantings are in Chile (675 ha) and California (1,373 ha), while other countries have much more limited, albeit growing, plantings.
Despite this global distribution, the Mediterranean basin remains the heartland of Carignan, with France’s planting dwarfing those of other countries, also for historical reasons.
From this perspective, Sardinia, Spain, France and Chile offer particularly interesting comparisons, as they represent four distinct approaches to the grape.
The nature of Carignano
Carignano is a late-budding and very late-ripening variety with excellent drought resistance. It therefore requires a warm climate and a long growing season to reach full phenolic ripeness. Naturally high-yielding—with potential yields exceeding 200 hL/ha—Carignano was historically prized for quantity rather than quality. This made it a workhorse grape, widely planted for its yields.
At such yields, wines were typically diluted, with low flavour intensity, yet marked by high acidity and high tannins. Large-scale vine-pull schemes within the EU led to a dramatic reduction in plantings in France, where Carignano was often replaced by other varieties. In Sardinia, however, the decline was far more limited.
For the production of fine wines, yield control is essential. One natural limiting factor is vine age: vines over 50 years old naturally produce lower yields, while simultaneously increasing flavour concentration. Warm, dry climate during the growing season is particularly well suited to achieving full ripeness, as Carignano performs poorly in humid conditions.
Given its natural vigour, Carignano is ideally suited to bush-vine training, which helps regulate growth and further reduce yields. The variety is also best adapted to hand harvesting, as the bunches are firmly attached to the vine.
Carignano naturally brings high acidity, deep colour, and very firm, occasionally bitter, tannins to its wines, making careful winemaking essential to achieve balance. For these reasons, the best examples of varietal Carignano wines are either the product of old bushvines, or softened by carbonic maceration and blended with finer varieties.
In terms of aromatic profile, Carignano wines usually exhibit black fruit aromas, herbal notes, spices, with a peculiar rustic character. Depending on the area of production, Carignano wines can also show subtle floral notes and herbaceous aromas. With ageing, tertiary notes of meat and game are typical.
Given that it is a wine with high acidity and high tannins, it is a natural candidate for ageing, with its best examples – produced with low yields from old vines – showing a very high ageing potential. Blending opportunities also abound, especially with softer varieties like Grenache, as the two varieties complement each other beautifully.
While the below summary of Carignan in Sardinia, Spain, France and Chile is obviously an uber-simplification, it is still helpful as a basic cornerstone for comparison.
Sardinia: Elegance from Sand and Sea
In Sardinia, Carignano finds its natural home in the Sulcis region, in the island’s south-west corner. The Sulcis region is characterised by a warm and dry Mediterranean climate, with constant sea breezes further favouring evapotranspiration and thus moderating yields.
The region’s defining feature is its sandy soils. These soils prevented the spread of phylloxera, allowing many vineyards to remain ungrafted, a rarity in modern viticulture. Many vines exceed seventy or even one hundred years of age, producing naturally low yields and highly concentrated fruit.
The resulting wines typically display: ripe black cherry and blackberry; Mediterranean herbs; balsamic notes; saline minerality; high yet ripe tannins.
Perhaps surprisingly, Sardinian Carignano often combines concentration with elegance. The sandy soils appear to soften the naturally robust tannic structure of the grape, producing wines that can be both powerful and remarkably refined. The uniqueness of Sardinian Carignano also lies in its creamy, almost velvety texture.
Southern France: The Backbone of the Languedoc
If Sardinia represents Carignano’s most elegant face, southern France showcases its structural side.
For much of the twentieth century, Carignan was one of the most widely planted varieties in France, particularly throughout the Languedoc-Roussillon region. Its reputation suffered because it was frequently grown at very high yields to satisfy demand for inexpensive wine. Therefore, because of its workhorse reputation, plantings of Carignan decreased significantly in France as a result of EU-funded pull out schemes.
Today, Carignan remains an important blending component across much of Languedoc-Roussillon, where it contributes acidity, colour and structure to many appellation wines. In Corbières AOC and Fitou AOC, Carignan is a principal grape variety and in nearly all other appellations it is an option. In parts of the Languedoc, carbonic or semi-carbonic maceration is also used to soften Carignan’s naturally firm tannins, producing wines that are more approachable in their youth.
However, today, Carignan is increasingly reputed for the wines that can be produced from old vines. Many of the region’s best producers preserve ancient Carignan vineyards, often cultivated on schist or limestone soils, to produce varietal wines.
In terms of aromatic profile, French Carignan typically offers: black olive; blackberry; dried herbs; liquorice; garrigue; or earthy and savoury notes.
Compared with Sardinian examples, French Carignan generally shows higher perceived acidity and firmer tannins, probably thanks to its slightly fresher climate; and firmer tannins and less overt fruit concentration; probably due to the influence of the schist and limestone soils. The wines often feel more rustic, but also exceptionally age-worthy.
Spain: Mazuelo and Mountain Freshness
Carignano/Carignan is known in Spain as Mazuelo (or Cariñena, or Samsó in Catalonia). Although often overshadowed by Garnacha and Tempranillo, Mazuelo continues to play an important role in several Spanish wine regions.
Historically, it became particularly important in Rioja, where it was valued for contributing acidity and structure to blends, where however it makes up just over 2 per cent of plantings.
Today, some of the most exciting examples come from higher-altitude regions such as Priorat, Montsant, and Cariñena, where old vines thrive in poor soils and challenging conditions. In Priorat and Montsant, Mazuelo constitutes about one third of plantings. In Priorat, old-vine Mazuelo frequently contributes elegance and tension to blends dominated by Garnacha. Mazuelo is particularly well suited to harsh conditions and generally grown in the warmest sites. Perhaps more than anywhere else, altitude plays a crucial role in shaping modern Spanish Mazuelo. Cooler nights preserve acidity and aromatic precision, allowing wines to combine Mediterranean ripeness with remarkable freshness.
Spanish Mazuelo often displays aromas of: black cherry and plum; dried flowers; graphite; herbs; and mineral notes, often linked with the typical mica soils so common in Priorat and around.
Compared with Sardinian Carignano, Spanish examples often feel: more angular; more mineral; less immediately fruit-forward; and slightly more austere in youth.
Chile: A New World Renaissance
Perhaps the most surprising Carignan success story comes from Chile. The variety was introduced in the 1940s but remained largely overlooked until producers in the Maule Valley began rediscovering ancient dry-farmed bush vineyards planted after the devastating earthquake of 1939. The revival of Chilean Carignan is closely linked to VIGNO (Vignadores de Carignan), an association created to protect and promote old-vine, dry-farmed Carignan from Maule, particularly from the area of Cauquenes in the south of the region towards the coast.
These old bush vines, cultivated without irrigation in granitic soils, produce wines of extraordinary character.
Chilean Carignan often exhibits aromas of: raspberry; blackberry; black cherry; violet; black pepper; herbs; and earthy notes.
Compared with Mediterranean examples, Chilean wines typically show: brighter acidity; more vibrant fruit; greater floral intensity; and a slightly more linear structure.
The cooler Pacific influence coming from the sea and the preservation of very old vineyards have helped create a style that many critics consider among the world’s finest expressions of Carignan. The wines often combine Old World structure with New World fruit purity.
Conclusion
Carignano’s story is one of redemption. Once regarded as little more than a productive workhorse, it is increasingly recognised as one of the Mediterranean’s most fascinating grape varieties and one that shows one of the greatest potentials, as the quality is still increasing. Few grapes can simultaneously offer freshness, concentration, complexity, structure, and such a transparent expression of place.
Among its many homes, Sardinia remains unique. The island’s ungrafted old vines, sandy soils, and maritime climate produce a style that combines richness, creaminess and elegance in a way rarely found elsewhere. It is arguably one of Carignano’s greatest expressions.
Yet comparing Sardinian Carignano with Carignan from France, Mazuelo from Spain, and Carignan from Chile highlights something even more interesting: the extraordinary ability of this grape to adapt while retaining its identity.
The grape remains the same. The voice changes. In Sardinia it speaks with a maritime accent; in southern France with a more rustic and savoury tone; in Spain with tension and mineral precision; in Chile with freshness and floral energy. Few varieties reveal terroir so clearly while remaining unmistakably themselves..
