The Secrets to Argentina’s Malbecs

Certain regions of the world are well-known for producing exceptional wines. Burgundy producing Pinot Noir, or Napa Valley producing Cabernet Sauvignon for example.  There is usually something about their terroir that brings out the best of their grapes, which then makes it into the wines.

What is it about Argentina that makes Malbec special?  There are a few factors: altitude, climate, and soil.  Some may also say that water and the new generation of winemakers also contribute to Argentinean Malbec’s quality.

From Mendoza north to Salta, the elevation at the foot of the Andes mountains increases from 300 to 2700m, with vineyards planted at all elevations.  Altitude contributes to a variety of microclimates with varying intensities of sunlight to ripen the grapes.  The more intense sunlight has caused the Malbec grapes in these areas to form thicker skins, which provides more tannins and deeper colour to the wine, as well as affect the aromas and flavours in the wine.


The climate in Argentina, on the eastern slopes of the Andes mountains, is very dry.  As weather moves from west to east, from Chile, clouds with moisture are pushed up the western slopes of the mountains which causes the clouds to precipitate by rain or snow, so that when the clouds come over the mountains and down the eastern slopes of Argentina there is no more moisture.  Plus as the clouds move downslope, the air is compressed; compression generates heat so that the Argentinean vines get warm to hot, dry air flowing over them.  This helps to keep out fungal diseases that thrive in cooler, damp conditions so that Argentina can more easily produce organic wines.


When you drive through a mountain range you notice that the higher mountains tend to be bare rock, with vegetation in the valleys.  Vegetation can only grow successfully up to a certain elevation, known as the “tree line”. Higher elevations plus leeward slopes (e.g. the eastern Andes) results in low rainfall and increased exposure to solar radiation, which dries out the soil, resulting in a localized arid/desert environment.  With the lack of vegetation in these areas of Argentina, there is little organic material to enrich the soil.  The soil is basically decomposed rock from the mountains. This lack of organic matter leads to restricted vine growth.  The lack of nutrients and dryness of the soil affects the flavour development of the grapes.

Putting It All Together

The quality of Argentinean Malbec has increased as the winemakers learn more about the terroir and use best practices in the winery.  The world has noticed.  In 1993 there were only 10 exporting wineries in Argentina; in 2017 there are now 424 exporting wineries (there are 881 wineries in total).  Total wine production of Malbec and other grape varieties has grown as well from 25 million litres exported in 1993 up to 273 million litres in 2017.

The flavours of the average Argentinean Malbec may include the following (in relative proportion from highest to least):

  • Red berries
  • Plums
  • Jam
  • Violets
  • Blackberries
  • Eucalyptus
  • Cinnamon and cloves
  • White pepper
  • Rosemary and Thyme

Cooler regions will tend to show more red fruit character while warmer regions will show more spicy and herbal characters.

I and other trade people had a chance to try a flight of Argentinean Malbecs to see the differences of terroir on the wine, as well as to recognize the quality of the wine produced.  As you may know, I was once the Coordinator and Cellar Master for the South World Wine Society in the 1990s.  I distinctly remember a tasting we had of Argentinean Malbecs.  From that tasting, I could easily pick out a glass of Malbec easily as the wine was a very distinct ruby colour.  Fast forward to 2018, with the flight of wines in front of me, I did not see a ruby coloured Malbec; they were all deep garnet in colour.  I asked speaker and winemaker Marcelo Pelleriti about this change in colour.  He paused then noted in the 1990s Malbec wines were produced from grapes that were from a higher tonnage and could have been somewhat diluted to give the ruby colour.  He said that now, viticultural practices are more stringent, producing small tonnages and winemaking practices are more stringent, which could be the reason for the garnet colour.

A Few Malbec Blends

Malbec can also be blended with other grape varieties.  Red blends are a hot category in the United States.  Here are four red blends that I enjoyed at the tasting.

Masi Corbec 2015 – A blend of Corvina (an Italian grape) and Malbec grapes that have been dried before fermentation.  Known as the Appassimento method in the Veneto region, for Amarone, which Masi is well-known. This wine was opaque garnet with a ruby tinge. Medium intensity Old World oak nose.  Fuller body, round with medium tannins.  A mix of red and black fruits, and raspberries, along with some sweet spices and oak.  There is bright acidity to this wine that makes the fruit flavours shine.  Firmer tannins on the finish along with some sweetness.  4 stars4.5 stars

Mascota Vineyards Unanime 2014 ($28.99) – A blend of 60% Cabernet Sauvignon, 25% Malbec, and 15% Cabernet Franc.  Opaque garnet coloured.  Lots of capsicum on the nose, along with cedar, nutmeg, tea leaves and dark fruits.  medium plus body, dry with medium acidity.  Ripe black fruit and sweet spices. You get tart red fruits and firmer tannins on the finish.  Some roundness. 4 stars4.5 stars

Clos de Los Siete 2014 ($25.99) – a wine made in collaboration with Michel Rolland, a Bordeaux-based oenologist. A blend of 54% Malbec, 18% Merlot, 13% Cabernet Sauvignon, 8% Syrah, 4% Cabernet Franc, and 3% Petit Verdot. This wine is opaque garnet in colour.  Unfortunately, the nose was closed when I tasted it.  The wine is dry, mineral, a little round in the mouth, with fine tannins.  Bright, sweet red fruit flavours. 4 stars4.5 stars

Familia Zuccardi Tito Zuccardi 2013 ($46.99) – 80% Malbec, 10% Cabernet Sauvignon, and 10% Ancellotta (not a grape that I am familiar with, but Wikipedia notes it “…is a wine grape variety mainly grown in the Emilia-Romagna region of Italy, but also in some other parts of north Italy, and in south Switzerland.”) This wine was opaque black in the glass.  Dark black fruit aromas as well as some dustiness.  Fuller body, ripe and round black fruit, with a hint of sweet spices and oak.  Firmer tannins.  Some sweetness. 4 stars4.5 stars
