Cabernet Sauvignon and Cabernet Franc are two distinct red-wine grape varieties with a close family relationship. Cabernet Sauvignon is generally fuller-bodied, darker-fruited and more tannic. Cabernet Franc is often lighter to medium-bodied, more aromatic and fresher, with red-fruit, floral, peppery or herbal notes.
Those are useful starting points, not rules. Climate, site, ripeness, winemaking, oak, blending and bottle age can change either wine considerably.
Highlights
- Cabernet Franc is one of Cabernet Sauvignon’s parents, but the grapes are not the same.
- Cabernet Sauvignon usually brings darker fruit, deeper colour, fuller body and firmer tannin.
- Cabernet Franc often brings red fruit, aromatic lift, freshness and herbal or peppery character.
- Cabernet Franc can make powerful, structured and ageworthy wine when grown and made that way.
- Cabernet Sauvignon is widely grown and highly important in Australia; Cabernet Franc is grown here on a much smaller scale.
- “Cabernet” and “Cabernets” can mean different things on an Australian wine label.
- The better choice depends on the style you enjoy, not on one grape being objectively better.
The family relationship between the two grapes
Cabernet Sauvignon and Cabernet Franc are both dark-skinned varieties of Vitis vinifera, the species that includes most familiar wine grapes.
DNA research established that Cabernet Sauvignon is the offspring of Cabernet Franc and Sauvignon Blanc. In other words, Cabernet Franc is a parent of Cabernet Sauvignon. This does not make Cabernet Franc a weaker, younger or less important version of Cabernet Sauvignon. They remain separate varieties with their own vineyard behaviour and wine styles.
The exact historical circumstances of the cross are uncertain. It is generally described as probably spontaneous rather than a documented breeding project.

Cabernet Sauvignon at a glance
A useful starting profile for one of the world’s major red-wine grapes.
Fruit
Blackcurrant and other dark-fruit associations are common, with red fruit in some examples.
Structure
Often medium to full bodied, with noticeable tannin and acidity.
Savoury notes
Herbal, leafy, cedar or tobacco-like characters may appear.
Variation
Climate, site, vintage, blending, extraction and oak all change the result.
RememberCabernet has recognisable tendencies—not a single fixed taste.
Tannin is the drying, slightly grippy sensation that can make your mouth feel firmer after a sip. You can learn more in What Are Tannins in Wine?.
Why the same grape can taste different
A grape variety provides a starting point, but it does not write the entire tasting note.
Climate and site
Cabernet Sauvignon generally benefits from adequate warmth and a long enough growing season to ripen fully. In Australia, it is grown in warm inland areas as well as moderate and cooler regions. Coonawarra, Margaret River, Barossa Valley, Langhorne Creek and McLaren Vale are among the Australian contexts associated with Cabernet Sauvignon.
Cabernet Franc is often well suited to cooler conditions. A cooler site can preserve acidity and produce redder fruit, lighter body and more prominent floral, peppery or leafy notes. Sunbury in Victoria is a useful Australian example: Wine Australia notes that Cabernet Franc may suit the region better than Cabernet Sauvignon in many vintages.
These are regional tendencies rather than promises. Aspect, elevation, soil, water availability, wind and vineyard management all matter too.
Ripeness
Earlier harvesting or cooler conditions can make leafy, herbal or capsicum-like notes more noticeable in either grape. Greater ripeness and warmth often bring darker, riper fruit and a fuller texture.
Green or herbal character is not automatically a fault. It can be part of a wine’s style, although excessive unripe character may make a wine feel hard or unbalanced. Nor does every Cabernet Franc taste like capsicum, or every Cabernet Sauvignon taste like blackcurrant.
Winemaking and oak
Extraction, fermentation temperature, skin contact, harvest timing and maturation can all change colour and tannin. A more gently extracted Cabernet Sauvignon may feel approachable earlier, while a ripe Cabernet Franc can be made dense and structured.
Oak can add cedar, vanilla, toast, smoke and spice to either wine. Bottle age can also shift fresh fruit towards savoury, earthy, tobacco or leather-like notes. Oak and age should not be mistaken for fixed grape characteristics.
Cabernet Franc in blends and varietal wines
Cabernet Franc is an important blending partner, particularly in Bordeaux-style blends. In a blend, it can add fragrance, red fruit, freshness and herbal or floral complexity. Cabernet Sauvignon commonly contributes darker fruit, colour, tannin and structure.
Cabernet Franc can also be bottled as a varietal wine, meaning the wine is made principally from that grape. A varietal Cabernet Franc may show its aromatic and fresh character more clearly than a blend, although the final style still depends on the vineyard and winemaking.
Australian labels deserve a little attention here. Under Wine Australia guidance, “Cabernet” used as a varietal term is a synonym for Cabernet Sauvignon, while “Cabernets” can refer to a blend involving Cabernet Sauvignon, Cabernet Franc and/or other traditional Bordeaux varieties, subject to labelling requirements. The plural matters.
The word “Cabernets” therefore does not necessarily mean a bottle contains only Cabernet Sauvignon.
Cabernet Sauvignon and Cabernet Franc in Australia
Cabernet Sauvignon is one of Australia’s principal red varieties and is grown across many regions. Australian examples can range from fresh, finely structured wines to rich, ripe and powerful styles.
Cabernet Franc is also grown in Australia, but on a much smaller scale. Historical Wine Australia data recorded 333 hectares planted in 2015 and 1,180 tonnes crushed in 2019. Those figures are useful for showing its relative scale, but they should not be treated as current national totals.
Cabernet Franc is often used in blends, although varietal and Cabernet Franc-led Australian wines exist. Because current national data is limited, it is safer to say that Cabernet Franc is grown in several Australian regions than to present an exhaustive regional map.

How to taste the difference
If you can taste the two side by side, ask:
- Is the colour deep and opaque, or brighter and more translucent?
- Does the wine feel broad and dense, or lighter and more lifted?
- Are the tannins firm and drying, or finer and less forceful?
- Does the fruit suggest blackcurrant and blackberry, or cherry and raspberry?
- Do floral, peppery or herbal notes stand out?
- How much of the character seems to come from oak?
A drinker looking for dark fruit, body and firm structure may prefer Cabernet Sauvignon as a starting point. Someone drawn to red fruit, freshness, aromatic lift and herbal complexity may prefer Cabernet Franc.
But the label alone cannot settle the question. A ripe, warm-climate Cabernet Franc may be fuller and darker than expected, while a cooler-climate Cabernet Sauvignon may be fresher and more restrained.
Frequently asked questions
Is Cabernet Franc the same as Cabernet Sauvignon?
No. They are separate grape varieties. Cabernet Franc is one of Cabernet Sauvignon’s parents.
Which is fuller-bodied?
Cabernet Sauvignon is generally fuller-bodied, but a ripe Cabernet Franc can also be medium- to full-bodied. Winemaking and climate matter.
Which has more tannin?
Cabernet Sauvignon often has denser, more pronounced tannin. Cabernet Franc can still be firmly tannic, especially in structured or highly extracted wines.
Is Cabernet Franc always herbal?
No. Herbal notes are a common association, particularly in cooler or less ripe examples, but Cabernet Franc can also show ripe red and dark fruit, floral character and spice.
Which grape is better for ageing?
Neither guarantees ageworthiness. A balanced wine with sufficient acidity, tannin, concentration and careful maturation may age well, regardless of which grape is used.
What does “Cabernets” mean on an Australian label?
It can indicate a blend involving Cabernet varieties and other traditional Bordeaux varieties under Australian labelling guidance. It is not automatically the same as “Cabernet”, which is used as a synonym for Cabernet Sauvignon.
