Cabernet Sauvignon (say it cab-er-nay so-vin-yon, or just Cab like the rest of us) is the most famous red wine grape in the world, the wine behind many of the bottles people save for a special occasion. Yet if you are new to it, that first sip can be a surprise. It is bold, dry, and grips the mouth in a way that lighter reds do not.
We pour a lot of Cabernet in the tasting room at Boschkloof Wine Farm on Polkadraai Road, and “what does it actually taste like” is one of the questions we hear most. The honest answer is that it tastes of dark fruit and firm structure, but there is real pleasure in learning to read it.
By the end of this guide you will know exactly what Cabernet Sauvignon tastes like, whether it is sweet or dry, why it grips your palate, and how the Stellenbosch style compares.
TL;DR
- Cabernet Sauvignon tastes of blackcurrant, black cherry, and dark plum, with notes of cedar, tobacco, and sometimes a leafy or minty edge.
- It is a dry, full-bodied red with firm tannins that grip and dry the mouth.
- It is not sweet. The bold, ripe fruit can feel sweet, but there is little or no sugar in the glass.
- Oak ageing adds vanilla, spice, and a smooth, savoury depth.
- South African and Stellenbosch Cabernet tends to show ripe cassis fruit with a fresh, structured finish.
The quick answer
Cabernet Sauvignon tastes of dark fruit, mainly blackcurrant, blackberry, and black cherry, wrapped in firm, mouth-drying tannins. Alongside the fruit you will often find cedar, tobacco, pencil shavings, and a green, leafy note, with vanilla and spice when the wine has been aged in oak.
It is full-bodied and dry, with a long, structured finish that lingers. The first thing most people notice is the grip, a slight drying sensation on the gums and tongue. That is the tannin, and it is a signature part of the Cabernet experience.
What is Cabernet Sauvignon?
Cabernet Sauvignon is a red wine grape, so the wine is always red, never white. It is the most widely planted wine grape on earth and the backbone of the great red wines of Bordeaux, as well as Napa Valley, Stellenbosch, and beyond.
The grape itself is small and thick-skinned, which is exactly why the wine tastes the way it does. Those thick skins give deep colour, dark fruit, and plenty of tannin. It ripens late, so it needs warmth and sun, which is part of why it does so well in the warmer red-wine wards of Stellenbosch.
What does Cabernet Sauvignon taste like in detail?
Slow down with a glass and you can pick out distinct layers. These are the characteristics of Cabernet Sauvignon worth looking for.
Cabernet Sauvignon tasting notes:
- Blackcurrant, also called cassis, the classic Cabernet flavour
- Blackberry, black cherry, and dark plum
- Cedar, pencil shavings, and cigar box
- Tobacco, leather, and dried herbs in older wines
- A green, leafy, or minty note, especially from cooler sites
- Vanilla, baking spice, and mocha from oak ageing
The texture matters as much as the flavour. Cabernet is full-bodied and firm, with tannins that dry the mouth and a finish that goes on and on. Young examples can taste tight and grippy, while age softens them into something smoother and more savoury.
Is Cabernet Sauvignon sweet or dry?
Cabernet Sauvignon is a dry wine. This is one of the most common questions, and the answer is clear, there is little or no sugar in a standard bottle.
The confusion comes from the fruit. Cabernet is full of ripe, dark berry flavour, and ripe fruit can read as sweetness even when the wine is bone dry. Add the vanilla from oak and a warm, generous body, and a good Cabernet can feel rich and almost sweet on the first sip. What you are tasting is ripeness and oak, not sugar. If anything, the firm tannins make it taste drier, not sweeter.
Why does Cabernet Sauvignon grip your mouth?
That drying, grippy feeling is tannin, and it is central to what Cabernet is. Tannins come from the grape skins, pips, and the oak barrels the wine ages in. Because Cabernet has thick skins, it has a lot of them.
Tannin is not a flavour so much as a sensation, a slight grip or chalkiness on the gums and tongue. It is also why Cabernet loves rich, fatty food. The protein and fat in a steak soften the tannins and make the wine taste smoother and rounder. It is the same reason a young, firm Cabernet benefits from a little time in a decanter before you drink it.
How oak and age change the taste
Cabernet rarely tastes the same young as it does with a few years behind it.
A young Cabernet is all about primary fruit, bold blackcurrant and blackberry, with firm, sometimes sharp tannins. Time in oak adds vanilla, spice, cedar, and a smoother texture. With bottle age, the fruit settles and savoury, tertiary notes appear, think tobacco, leather, dried herbs, and cigar box. This is why serious Cabernet is so often cellared. It genuinely improves and grows more complex over five, ten, or more years.
It is also why good Cabernet costs what it does. Thick skins, small crops, and years in oak all add up, and you are paying for structure that lasts.
What does South African Cabernet Sauvignon taste like?
South African Cabernet, and Stellenbosch Cabernet in particular, has a style of its own. Stellenbosch is the country’s Cabernet heartland, and the wines tend to balance ripe Cape fruit with real freshness and structure.
Expect generous blackcurrant and dark berry fruit, often with a whiff of mountain fynbos over the cassis and a fresh, firm finish from the granite and decomposed-granite soils. The best examples are built to age and sit comfortably alongside the world’s finest. Our own Stellenbosch Cabernet grows on these granite-rich soils on Polkadraai Road, and it shows that mix of ripe fruit and freshness we love.
How it compares to other reds
Tasting Cabernet next to other reds is the fastest way to understand it.
Against Merlot, Cabernet is firmer, more structured, and more savoury, while Merlot is softer and rounder. Our guide to Cabernet Sauvignon and Merlot breaks this down in detail. Against Shiraz, Cabernet is more about firm tannin and blackcurrant, where Shiraz brings pepper and spice, which we cover in Merlot and Shiraz. Against a light red like Pinot Noir, the difference is night and day, Cabernet is far bigger, darker, and grippier.
If Cabernet feels like a lot on your first try, you are not doing it wrong, that grip is the point. Have it with a bit of steak or biltong and watch it soften. And if you want a gentler way in, a Merlot or a Cabernet-Merlot blend eases you toward the bold stuff.
What food brings out the best in Cabernet?
Because of its tannin, Cabernet shines with rich, savoury food.
- Steak, especially a fatty rib-eye or sirloin
- Roast lamb and lamb chops
- Slow-cooked beef short rib and oxtail
- Venison and game
- Mature, hard cheeses like cheddar
Avoid pairing it with delicate fish or light salads, where its power simply overwhelms the plate. For the full approach, our beginner’s guide to wine pairing is a good place to start.
How to serve Cabernet Sauvignon
A few small things help Cabernet taste its best. Serve it a touch below room temperature, around 16 to 18°C, which on a warm Cape day often means twenty minutes in the fridge first. Too warm and the alcohol dominates, too cold and the fruit goes quiet.
Give a young, firm bottle some air. Pour it into a decanter or even a jug about thirty minutes before dinner, and the tannins soften while the aromas open up. A larger glass helps too, since it gathers all that dark fruit and spice.
Taste it for yourself at the cellar

Frequently Asked Questions
Is Cabernet Sauvignon sweet or dry?
Cabernet Sauvignon is a dry wine with little or no sugar. Its ripe, dark fruit and the vanilla from oak ageing can make it feel rich and almost sweet, but that is fruit and oak rather than sugar. The firm tannins actually make it taste drier.
Is Cabernet Sauvignon a red or white wine?
Cabernet Sauvignon is always a red wine. It is made from a thick-skinned dark grape that gives deep colour, dark fruit, and firm tannins. There is no white version of Cabernet Sauvignon.
Where does Cabernet Sauvignon come from?
Cabernet Sauvignon originated in Bordeaux, France, where it is the backbone of the famous Left Bank red blends. It is now grown around the world, including Napa Valley, Australia, Chile, and South Africa, where Stellenbosch is the leading region.
Why does Cabernet Sauvignon dry out my mouth?
That drying, grippy feeling is tannin, which comes from the grape’s thick skins and from oak ageing. Cabernet is high in tannin, which is why it grips the palate. Pairing it with rich, fatty food softens the tannins and makes the wine taste smoother.
What does Cabernet Sauvignon taste like compared to Merlot?
Cabernet is firmer, more structured, and more savoury, with grippy tannins and blackcurrant fruit. Merlot is softer and rounder, with plummy fruit and gentle tannins. Cabernet is the bolder, more serious of the two, while Merlot is the easier, smoother one.
Does Cabernet Sauvignon get better with age?
Yes, good Cabernet often improves for years in the bottle. The firm tannins soften, the fruit settles, and savoury notes like tobacco, leather, and cedar develop. This is why quality Cabernet is one of the most cellared red wines in the world.
So, what should you expect from a glass of Cabernet?
Cabernet Sauvignon tastes of bold dark fruit, cedar, and spice, wrapped in firm, dry tannins that grip the palate and reward rich food. It is serious, structured, and built to age, which is exactly why it is the most loved red grape on earth. The best way to know it is to taste it, so book a tasting or open a bottle with a good steak and see what you find.
