Malbec

Say it mal-BEK Also Côt · Cot · Auxerrois

Malbec is a dark-skinned red grape from south-west France, where it is called Côt and is the main grape of Cahors. Most of the world's Malbec now grows in Argentina, above all in Mendoza. The wines are deeply coloured and usually dry and full-bodied, with plum, blackberry and violet aromas and noticeable tannin. Mendoza bottles are often plush and ripe; Cahors tends to be firmer and darker-fruited. Altitude, producer and ageing change the style, so the grape name alone cannot tell you how a bottle will taste.

Understand the grape

Getting to know the grape

Malbec has blue-black berries and makes some of the deepest-coloured red wine, often with a violet edge when young. Typical aromas are plum, blackberry and black cherry, with violet, cocoa and sweet tobacco; oak can add vanilla and toast. Body is full, tannin is noticeable but often rounded in warmer, lower sites, and acidity keeps the wine fresh enough to take grilled meat. Alcohol tends to be generous. Higher vineyards in Argentina often give fresher, more floral wines than lower ones, though soil, producer and picking date matter as well.

The grape is French. Argentina's national wine institute, the INV, describes it as an old cross between Prunelard and Magdeleine Noire, and the Cahors interprofession calls Cahors the cradle of Malbec. Auxerrois appears in French records from 1539, and the name Malbec from the 18th century. A French agronomist, Michel Aimé Pouget, brought Malbec to Mendoza in 1853 among plants from Chile. Argentina counted 58,600 hectares in 1962, only 10,500 by 1990 after a long crisis, and 47,064 at the end of 2024, which is 23.5 per cent of all its vines.

Where Malbec changes

Grape to place

Compare how the grape grows and tastes in these places. Each guide explains the local wines; the Atlas shows where they come from.

01

Mendoza

Mendoza has 39,856 of Argentina's 47,064 hectares of Malbec, about 85 per cent (INV, 2024). Vines grow in irrigated oases below the Andes, between about 430 and 2,000 metres. Luján de Cuyo and the Uco Valley are the names to learn: Luján de Cuyo vineyards start above 850 metres, the Uco Valley's lie between 900 and 1,700.

02

Cahors & Lot Valley

Cahors is Malbec's French home, where the grape is called Côt. The appellation requires at least 70 per cent Malbec, with Merlot and Tannat as the other permitted grapes. About 60 per cent of the vineyard lies on terraces beside the River Lot and about 40 per cent on the limestone plateaus above, and the two settings can give different wines.

03

Salta

Salta has 1,714 hectares of Malbec (INV, 2024), the third-largest area after Mendoza and San Juan and nearly half of the province's vines. Cafayate holds about 77 per cent of that Malbec. Vineyards in the dry Calchaquí Valleys sit above 1,700 metres, and the reds tend to be deeply coloured, with ripe plum and blackberry and soft tannin.

What changes the result

Vineyard and cellar

The ripeness of the grapes, contact with their skins, and time in tanks or barrels all help shape the wine. Here is what to look for.

  • Altitude and irrigation

    Mendoza is dry, so vines depend on Andean meltwater carried by canals, with drip lines in many newer vineyards. In the Uco Valley the INV records a daily temperature range of about 15°C and says it favours deep colour and tannin. Higher vineyards often give fresher acidity, but altitude is one factor among several.

  • Picking time and extraction

    Earlier picking tends to keep fresher red fruit and acidity. Later picking brings riper, plusher black fruit and more alcohol. Long contact with the skins builds colour and tannin; gentler handling keeps the texture softer. Producers choose both according to site, vintage and the style they want.

  • Oak and other vessels

    French and American oak can add vanilla, chocolate and toast, and many Malbecs spend months in barrel. Concrete, large old casks and older barrels leave more of the fruit and violet character showing. Read the tasting description as well as the word oak, because the vessel matters less than how much flavour it adds.

  • Blending

    Cahors must contain at least 70 per cent Malbec and may add Merlot and Tannat. In Argentina a wine can name Malbec only if it holds at least 85 per cent of the grape, so a bottle may carry a little Cabernet Sauvignon, Merlot or another red. Malbec is also a minor grape in some Bordeaux blends.

  • Old and ungrafted vines

    Most vines are grafted onto American rootstock because of phylloxera, the root-feeding insect that reached Cahors in 1876 and destroyed most of its vineyard. Some old Malbec grows ungrafted in sandy ground, for example in Río Negro, where a few producers farm vines planted in the 1930s. Old vines bear smaller crops, though age alone does not make a wine better.

Read the label

On the bottle

A label may name the place instead of the grape. These names and terms help you work out what is in the bottle.

Malbec
In Argentina a grape name may appear only if the wine holds at least 85 per cent of that grape. A French bottle from Cahors may print the place and not the grape, so check the back label for Malbec or Côt.
Luján de Cuyo, Valle de Uco
Place names inside Mendoza. Luján de Cuyo is one of Argentina's two DOCs (Denominación de Origen Controlada), with its own rules. Valle de Uco is an IG (Indicación Geográfica) covering San Carlos, Tunuyán and Tupungato, and it contains smaller IGs such as Paraje Altamira. A smaller name says more about where the grapes grew than Mendoza does.
Reserva, Gran Reserva
Optional Argentine ageing terms, set at minimum ageing of 12 and 18 months for red wine. They describe time before release, not oak type, quality or taste.
Cahors
A red-only appellation in the Lot département in south-west France. At least 70 per cent of the wine must be Malbec, called Côt locally, and Merlot and Tannat are the only other grapes allowed. Cahors is a place name, not a style, though firm tannin and dark fruit are common.

At the table and in the cellar

Practical use

Serve

Serve Malbec around 16 to 18°C in a large glass. A warm bottle makes alcohol seem hotter, so a short time in a cool place helps. Young, structured bottles may soften after half an hour in a decanter.

Eat

Grilled beef is the familiar match: skirt steak with chimichurri, beef empanadas or a mushroom burger. The wine's tannin also suits lamb chops, aubergine and blue cheese. In Cahors, duck confit is a local dish worth trying. Sweet barbecue sauces can make the alcohol and tannin feel harder.

Keep

Many Malbecs are made to drink within three to eight years of the vintage. Better-structured wines from Mendoza and Cahors can be kept for five to ten years or longer. Ripeness alone does not predict ageing; acidity, tannin and storage matter too.

Taste it in three steps

Three bottles

You can try these bottles on separate occasions. Keep a note of the name, vintage and what you notice, then use the steps below to decide what to compare.

  1. 01

    Begin with Mendoza

    Start with a Malbec labelled Mendoza or Luján de Cuyo from a recent vintage. Notice the deep colour, plum and blackberry fruit, the grip of tannin and how full the wine feels in your mouth.

  2. 02

    Compare the Uco Valley

    Taste a Valle de Uco Malbec at a similar price, ideally from the same producer and vintage. Compare acidity, freshness and tannin. Soil and winemaking differ along with height, so treat the result as a comparison and not as proof of altitude.

  3. 03

    Finish in Cahors

    Try a Cahors. The label names the place, and the wine is often darker-fruited and firmer than the Mendoza bottles. Compare tannin and savoury flavours with the first two wines, then check the back label for the grapes.
