Shiraz gets the attention in Australia, but Cabernet Sauvignon is the variety that rewards patience. It ages longer, it changes more in the glass, and it asks more of the drinker. If Shiraz is a wine that greets you at the door, Cabernet is one that takes a while to warm up and then does not let go.
This guide covers what Cabernet Sauvignon does in Australian conditions, how to judge a bottle before you buy it, and how to decide whether to drink it now or leave it alone for five more years.
What makes Cabernet Sauvignon different
Cabernet Sauvignon is a natural crossing of Cabernet Franc and Sauvignon Blanc that emerged in Bordeaux in the seventeenth century. It has small berries with thick skins, and that ratio of skin to juice is the whole story: more skin means more tannin, more colour and more of the aromatic compounds that give the variety its signature.
That signature is remarkably consistent across the world. Blackcurrant sits at the centre of it, joined by black cherry, cedar, graphite, dried tobacco leaf and, in cooler or less ripe conditions, a green note that can read as capsicum, mint or eucalyptus. The structure is firm. Cabernet tannin grips the sides of the tongue in a way Shiraz tannin usually does not.
That grip is why the variety ages. Tannin and acidity together act as a preservative structure, and over years in bottle the hard edges soften while the primary fruit slowly converts into savoury, tertiary character: leather, cigar box, dried fig, forest floor. A young Cabernet and a mature one taste so different that people often assume they are unrelated wines.
Cabernet in Australian conditions
Australia grows Cabernet Sauvignon successfully in several very different climates, and the results diverge sharply.
In the warmer districts of South Australia, ripeness is reliable. The green, herbaceous side of the variety recedes and the fruit moves toward ripe blackcurrant and dark plum. Tannin is still present but rounder and more approachable young. These are generous wines that do not demand a decade of cellaring before they give anything back.
In Western Australia, particularly the maritime districts in the state's south west, the growing season is longer and more temperate. Cabernet from these conditions tends to keep more of its structural tension: tighter tannin, higher natural acidity, a finer and more linear shape, and aromatics that lean toward cedar and graphite rather than pure sweet fruit. These are wines built for the long haul.
Neither profile is the correct one. They serve different purposes, and a well-stocked cellar usually holds both.
Judging a bottle before you open it
Four label details will tell you most of what you need to know.
Region. A specific regional claim is more informative than a broad multi-state zone. It narrows the likely climate, and climate drives the style far more than winemaking does.
Vintage. With Cabernet, vintage tells you where the wine sits in its life. A 2020 Australian Cabernet is now around five years old. In warmer-region examples that is often the beginning of a good drinking window. In cooler-region examples it may still be an adolescent wine that will reward another three to five years.
Alcohol. Cabernet at 13.5 to 14 percent generally indicates a more structured, restrained interpretation. Above 14.5 percent expect a fuller, riper, softer-fronted wine.
Price relative to peers. Within a single producer's range, price usually tracks fruit selection and oak quality rather than marketing. A reserve or limited bottling normally means older vines, tighter selection, better barrels, or all three.
Cabernet Sauvignon across our range
Our Cabernet selection sits mostly in the 2020 vintage, which is convenient for comparison because it removes the vintage variable and leaves site and winemaking as the differences you are actually tasting.
The Larry No 10 Cabernet Sauvignon is our Western Australian example, and it is the one to reach for if you want the tighter, more structured, more classically austere reading of the grape. It is also the bottle in the range most likely to reward being left alone for a few more years.
The Toorak Estate Cabernet Sauvignon and the Blue Jack Cabernet Sauvignon, both South Australian and both 2020, sit in the warmer register: rounder tannin, riper blackcurrant, more immediate appeal. The Oz Stamp Cabernet Sauvignon Select Reserve draws from South Eastern Australia, a broader zone that tends to produce a balanced, accessible style.
Tasting two of these side by side is the fastest education in Australian Cabernet available. Open the Larry No 10 and one of the South Australian bottles on the same evening, pour both, and the influence of climate becomes obvious in a way no tasting note can convey.
Should you drink it or cellar it
The honest answer is that most Cabernet sold is drunk far too young, and a smaller number of bottles are held far too long. Both are avoidable.
A useful method is the three-bottle rule. If you like a wine enough to consider cellaring it, buy three. Open the first immediately and take notes. Open the second in two or three years. By then you will know whether the wine is improving or fading, and you can decide about the third with evidence rather than hope.
Signs that a Cabernet needs more time include tannin that dries the mouth aggressively, fruit that feels locked behind that tannin, and a short finish that seems to stop before it should. Signs that it is ready include tannin you notice as texture rather than as astringency, aromatics that have started to move from pure fruit toward cedar and tobacco, and a finish that lengthens as the bottle sits open.
Signs that you have waited too long include a brick or brown rim in the glass, dried fruit and vinegar notes, and a wine that falls apart within twenty minutes of opening.
Serving and food
Serve Cabernet Sauvignon at 16 to 18 degrees Celsius, the same as Shiraz. Young structured examples benefit from an hour of air. Decanting is genuinely useful here rather than merely theatrical, because Cabernet tannin needs oxygen to soften.
At the table, the variety has one near-perfect partner: fat and protein. Grilled beef, a rib roast, lamb, aged hard cheese. The protein binds to the tannin and the wine immediately feels softer and rounder. Cabernet with a well-marbled steak is one of the few pairings in wine that works on chemistry rather than convention.
Avoid pairing it with anything strongly sweet, anything with high vinegar content, and delicate seafood. Also be careful with heavily spiced dishes, since alcohol and chilli amplify each other.
A note on blends
Cabernet Sauvignon appears in blends as often as it appears alone, and in Australia the traditional partner is Shiraz rather than the Merlot of Bordeaux. The logic is sound: Cabernet supplies structure, tannin and aromatic definition while sometimes leaving a gap in the middle of the palate, and Shiraz fills exactly that gap with soft, generous fruit weight. A varietal label tells you the bottle contains at least 85 percent of the named grape under Australian labelling rules, so a small proportion of something else may still be present. This is not a compromise. Some of the country's most respected reds are built this way deliberately.
A closing note on patience
Cabernet Sauvignon is not a variety that flatters instantly. That is precisely its value. A bottle bought now and opened in five years will be a different wine from the one you paid for, and in a good example it will be a better one. Very few things you can buy for the price of a bottle of wine improve on their own while you do nothing at all.
