Classic Wine Grapes

Cabernet Sauvignon

Cabernet Sauvignon Grapes

Cabernet Sauvignon is the world's most planted red wine grape.

The name comes from its parents: Cabernet Franc and Sauvignon Blanc.

About Cabernet Sauvignon

Cabernet Sauvignon is a red wine grape considered a world`s classic.

The grape has its origins in Bordeaux, France, where it is mixed with other grapes (Merlot, Cabernet Franc, Petit Verdot, Malbec) to produce balanced and complex wines.

Bordeaux is located in the South West of France which translates into "maritime climate" with hot and dry summers and mild winters.

Cabernet Sauvignon is the king grape in the Left Bank of Bordeaux Wine Region.

Cabernet Sauvignon has small grains, ripens late and is a thick-skinned grape.

Thick skin means that the color of the wine is dark red and the wines usually vinifies full bodied.

Thick skin means also high tannins and great aging potential.

Good to know: China is the world´s largest red wine consumer country and, to meet the market, Cabernet Sauvignon is the most planted grape there too. By the way: China could become nr.1 wine producer in the world by 2021.

Cabernet Sauvignon DNA

Grape geneticist dr. Carole Meredith at University of California, Davis, and her team revealed in 1996 their DNA tests results.

Cabernet Sauvignon, Merlot, Hondarribi Beltza (from the Basque Country) and Carménère are all genetically related. They all originate from Cabernet Franc and they taste similar.

There is more: the Cabernet family shares with Sauvignon Blanc an aromatic molecule called Pyrazine , responsible of the green, veggie aromas. Think about Pyrazines next time you taste a Sauvignon Blanc from New Zealand!

Pyrazines are known to give "green aromas" like grass, mint, green bell peppers, green pepper, asparagus, sage, eucalyptus, jalapeño, cocoa powder, black pepper and black currant. In small doses this aromas are considered positive, while large quantities can make the wine taste "green", not good. Researcher have found that large quantities of leaves in the vine have a direct relationship with this green aromas.

Primary grape aromas in the Old World: blackcurrant, black cherry, cassis, violets, cedar tree and spice. In the New World you can find the same aromas as in the Old in addition to ripe, jammy berries, and earth.


Bad soil means higher quality grapes!

It sounds like a paradox but in poor soils the roots must work harder, branching off to find nutrients. This increases the root to soil surface.

Cabernet Sauvignon loves sand and gravel. The sand provides nutrients while the stones absorb the heat, help ripening and draining.

The better performance in the world is the gravel-based soil of the Médoc region on the Left Bank of Garonne river.

The Bordeaux Blend

Cabernet Sauvignon put Bordeaux region on the wine map.

Bordeaux wine style is imitated all over the world.

Famous Blends:

Cabernet Sauvignon Vinification

Cabernet Sauvignon can be vinified in red, rosé and Claret styles.

Bordeaux is known for its red wine blends (89%) and Cabernet Sauvignon is the king grape in the Left Bank of Garonne River. It is blended with Merlot, Cabernet Frank and smaller amounts of Petit Verdot, Malbec and Carménère.

The must (grape juice) and the skins macerates for 21 days (longer for bolder styles) to extract tannins and pigments.

Alcoholic Fermentation

The first fermentation called alcoholic starts above 16°C (60°F). Sugars are turned into alcohol while carbon dioxide and heat are released.

Alcoholic fermentation usually takes place in vats (steel or cement) where it is easy to control both temperature and speed of fermenation. An error at this stage can result in wine faults.

The pomace (skin+pips) is then pressed and mixed with the fermented must. Now can the second fermentation (malolactic) start.

Malolactic Fermentation (MLF)

Malolactic bacteria consume malic acid (naturally present in the grape) and convert it to lactic acid. MLF is essentially the conversion of malic acid into lactic acid. As a result the wines become rounder, fuller and less acidic. Practically easier to drink and to match with food.

Barrel Fermentation

After the two fermentations are completed, the wine is separeted from its lees (dead yeast cells) and sulfites are added to protect against oxydation. Now it´s time to sleep! Aging in oak and vats in Bordeaux varies between 12 to 24 months. Barrel Fermentation, storage, and aging will cause the wine to absorb taste from the wood, like vanilla, caramel, spices, smoke and toast flavors.

Claret (Clairet in french) is the oldest wine style in Boredaux. It means weak-colored (latin: clarus =clear) and looks like a dark rosé.

Claret is famous since the Middle Ages when Eleanor duchess d´Aquitaine and King Henry II of England marry and Bordeaux becomes English territory. The consequent tax exemption pushes the trade and ships loaded with Bordeaux wines cross the English Channel. Claret, thanks to the affordable price and short fermentation (arrives sooner in the markets) becomes ‘the Englishman’s drink’. This happy trade will last 300 years.

Originally, all red wines from Bordeaux were "Claret" wines.

Name confusion: today, in the UK, the word Claret is often used to define Bordeaux red wines in general: rom dark full bodied to more rosé looking ones.

Rosé wines are made with the same blend of grapes as Bordeaux red wines, but the contact between must and skin is shorter (max 12 hours). This explains the pink color. They have typical rosé aromas of strawberry, gooseberry and grapefruit.

Cabernet Sauvignon in Europe


Cabernet Sauvignon blend from Bordeaux in France is the most copied wine style in the world. Cabernet Sauvignon grape is king in the left bank of Garonne river. The major appellations are : Haut Medoc, Margaux, Saint Julien, Pauillac, Saint Estèphe and Pessac-Leognan.


Cabernet Sauvignon is particularly famous in Tuscany where it is blended with Sangiovese and Merlot to create the famous Supertuscan wines.


The increasing demand has pushed Spain to plant this grape varietal in different regions such Catalonia, Navarra and La Mancha. In Spain Cabernet Sauvignon grapes are blended with Tempranillo, Garnacha and Monastrell.

New World Cabernet Sauvignon


USA is the largest wine market in the world, and blended Cabernet Sauvignon is the number one selling wine. The best known regions are California (Napa, Sonoma) and Washington State.


Australia used to make heavy, oaky and powerful Cabernet Sauvignon blends, but the trend is rapidly changing and the new versions are less oaked, and better balanced, meeting the approval of a larger market.


The hot and dry mountain climate facilitates the ripening of Cabernet Sauvignon grapes. Here the Cabs are very similar to the Malbecs: full bodied and with an excellent price/quality ratio. High altitude and cold climate Cabs tend to express spicy, menthol and herbal aromas.


Chilean Cabernet Sauvignon style is often an easy drinking wine with soft tannins and aromas of mint, black currant, olives and smoke. Chilean Cabernet Sauvignon is a best value wine: a lot of quality for the money!

South Africa

South African Cabernet Sauvignon is more Bordeaux than California style, with cassis, violets, and cedar wood aromas. The good balance and affordable prices make it a winner.

New Zealand

New Zealand Cabernet Sauvignon is often blended with Merlot to produce an easy style Cab, ready to drink in 3 to 5 years. Dark fruits, cassis, raspberry and forest floor are typical aromas.
