Two of the most popular white wines in the world sit on the same shelf, at roughly the same price, in almost the same pale gold colour. One is a Chardonnay. The other is a Sauvignon Blanc. You have people coming over, supper is nearly ready, and you want to pour the right one.
This is a conversation we have most weeks in the tasting room at Boschkloof Wine Farm on Polkadraai Road. The Chardonnay vs Sauvignon Blanc question comes up more than almost any other, because the two grapes look alike in the glass but behave like opposites on the palate.
By the end of this guide you will know how each one tastes, which is drier, which suits your dinner, and why South Africa is a quietly brilliant place to drink both.
TL;DR
- Sauvignon Blanc is light, high in acidity, and almost always bone-dry, with green, zesty notes like lime, gooseberry, and cut grass.
- Chardonnay is fuller, rounder, and more flexible, ranging from crisp and unoaked to rich and buttery, with notes of citrus, peach, and sometimes vanilla from oak.
- Both grapes are dry by default. Chardonnay only tastes “sweeter” because riper fruit and oak make it feel softer and rounder, not because it has more sugar.
- Pick Sauvignon Blanc for fresh, light, herby food. Pick Chardonnay for richer, creamier, roasted dishes.
- For cooking, reach for an unoaked, crisp white. A simple Sauvignon Blanc or unoaked Chardonnay both work well.
The quick answer
Open Sauvignon Blanc when the food is fresh, sharp, or herby. Think a green salad with feta, fish off the braai with a squeeze of lemon, grilled prawns, or oysters. Its high acidity and green edge lift light flavours and cut through anything tangy.
Open Chardonnay when the food has weight or richness. Think roast chicken, creamy pasta, grilled crayfish in butter, or a soft, mushroomy risotto. Chardonnay has more body, so it sits comfortably next to richer plates instead of getting lost.
If you are not sure what is about to land on the table, an unoaked Chardonnay is the gentle all-rounder. It has enough body for most meals without the sharp bite that can make Sauvignon Blanc feel out of place.
You can also choose by your own taste rather than the food. Prefer something sharp and refreshing? Start with Sauvignon Blanc. Prefer something smooth and rounded? Start with Chardonnay.
Where each grape comes from
Both grapes were born in France, and that is roughly where the similarity ends.
- Chardonnay comes from Burgundy. It is the grape behind white Burgundy, Chablis, and a large share of Champagne. Chardonnay is famously a winemaker’s grape, which means its flavour depends heavily on where it is grown and what the cellar decides to do with it. Cool sites and no oak give something lean and citrussy. Warmer sites and time in barrel give something rich and golden.
- Sauvignon Blanc comes from the Loire Valley and Bordeaux. It is the grape behind Sancerre and Pouilly-Fumé. Unlike Chardonnay, Sauvignon Blanc is usually pushed in one clear direction, which is bright, dry, and high in acid. There is far less stylistic range, and that consistency is part of its appeal.
In South Africa, both grapes have found a happy home. Our Sauvignon Blanc thrives in cooler, coastal-influenced sites like Elgin, Constantia, Durbanville, and the granite slopes of Stellenbosch.
Chardonnay does beautifully in Robertson, Hemel-en-Aarde, and again in Stellenbosch, where cooler pockets keep the acidity fresh. According to Wines of South Africa, the country’s varietal range is one of the widest in the New World, which is why you can find world-class versions of both here.
How each one actually tastes
The fastest way to tell them apart is to slow down and pay attention to what is in the glass.
Sauvignon Blanc tasting notes:
- Lime, granadilla, gooseberry, and green pepper up front
- Cut grass and a fresh, herby lift
- A flinty, wet-stone note in cooler-climate examples
- Light to medium body, more lifted than weighted
- High acidity, usually the first thing you notice
Chardonnay tasting notes:
- Lemon, apple, pear, and white peach in cooler styles
- Melon, pineapple, and tropical fruit in warmer styles
- Vanilla, toast, butter, and a creamy texture when oak is used
- Medium to full body, with real weight on the palate
- Acidity that is fresh but softer and rounder than Sauvignon Blanc
Colour gives you a small clue too. Sauvignon Blanc is usually paler, with a slight green tint. Chardonnay tends to be a deeper straw or golden colour, especially when it has spent time in oak.
Which is drier, and which is sweeter?
This is the single most common point of confusion, so it is worth being clear. Both grapes are made dry in the vast majority of cases. Neither is a sweet wine by default.
Sauvignon Blanc almost always tastes crisp and dry, because its high acidity makes it feel sharp and clean. Chardonnay can taste “sweeter” or rounder, but this is usually an illusion.
Riper fruit, a fuller body, and the vanilla notes from oak all make Chardonnay feel softer and more generous, even when the actual sugar level is just as low.
So if you want the drier, sharper wine, choose Sauvignon Blanc. If you want a wine that feels rounder and richer while still being dry, choose Chardonnay.
If you genuinely want a sweet white, neither of these is your grape. You would be better off looking at a late-harvest wine or an off-dry Chenin Blanc instead. For more on that grape, our guide to Chenin Blanc and Sauvignon Blanc breaks down where it fits.
A quick comparison table
Here is the difference between Chardonnay and Sauvignon Blanc at a glance.
| Chardonnay | Sauvignon Blanc | |
|---|---|---|
| Body | Medium to full, more weight | Light to medium, lifted |
| Acidity | Fresh but rounded | High, sharp |
| Fruit profile | Lemon, peach, melon, tropical fruit | Lime, gooseberry, granadilla, green pepper |
| Oak influence | Common, adds vanilla and creaminess | Uncommon, mostly unoaked |
| Sweetness | Dry, but feels rounder | Dry and crisp |
| Best serving temp | 10 to 13°C | 7 to 9°C |
| Pairs well with | Roast chicken, creamy pasta, crayfish | Fish, oysters, salads, goat’s cheese |
What food each one wants
The simplest way to choose is to match the wine to the heaviest element on the plate.
Choose Sauvignon Blanc for:
- Goat’s cheese, feta, and green salads
- Fish off the braai, especially yellowtail and angelfish
- Grilled prawns, calamari, and steamed mussels
- Oysters and other fresh shellfish
- Asparagus and green vegetable mains
- Thai and other herb-forward dishes
- Sushi with a squeeze of lime
Choose Chardonnay for:
- Roast chicken with herbs and butter
- Creamy pasta and mushroom risotto
- Grilled crayfish or prawns in a butter sauce
- Smoked salmon and richer fish like kingklip
- Soft, buttery cheeses such as brie and camembert
- Roast pork or a Sunday lunch spread
- Mild, creamy curries
One pairing to avoid is Sauvignon Blanc with very rich, creamy food. The sharp acidity clashes with the fat and can leave the wine tasting thin or metallic.
For anything in cream or butter, Chardonnay is the better partner. If you want to go deeper on matching wine to food, our beginner’s guide to wine pairing covers the basics for South African tables.
Oaked vs unoaked Chardonnay
There is one more thing worth knowing, because it changes the Chardonnay vs Sauvignon Blanc decision quite a lot. Chardonnay comes in two broad styles.
- Unoaked Chardonnay is fermented in steel rather than barrels. It is fresher, leaner, and more citrus-driven, which actually brings it much closer to Sauvignon Blanc in feel. If you usually drink Sauvignon Blanc but want to try Chardonnay, this is the easy place to start.
- Oaked Chardonnay spends time in barrel, which adds vanilla, toast, butter, and a creamy texture. This is the richer, more luxurious style that people either love or find too much. It is also the style that pairs best with roast and creamy dishes.
If you have ever said you do not like Chardonnay, there is a good chance you mean heavily oaked Chardonnay.
An unoaked bottle is often a completely different, fresher experience, and well worth a second try before you write the grape off.
Sauvignon Blanc, by contrast, is rarely oaked in South Africa, with a small but growing number of barrel-fermented examples aside.
For the most part, what you taste is pure fruit and acidity, which makes it the more predictable of the two grapes from bottle to bottle.
How to choose on the shelf
A few quick rules help when you are standing in front of two unfamiliar labels.
For Sauvignon Blanc, look for:
- A vintage from the past two years, since freshness matters most
- A producer from a cooler ward such as Elgin, Constantia, Durbanville, or coastal Stellenbosch
- An alcohol level around 12.5 to 13%, which usually points to balanced picking
For Chardonnay, look for:
- Words like “unoaked” or “wooded” on the label so you know which style you are getting
- A producer from a cooler site such as Stellenbosch, Robertson, or Hemel-en-Aarde
- A vintage no older than three years for fresh styles, or a few years more for premium wooded wines built to age

Frequently Asked Questions
Which is better, Chardonnay or Sauvignon Blanc?
Neither is better. They suit different moods and meals. Chardonnay is rounder and fuller, which works for richer food and colder weather. Sauvignon Blanc is crisp and fresh, which works for lighter meals and warm days. The best choice is the one that matches what is on your plate.
Is Sauvignon Blanc sweeter than Chardonnay?
No. Both are almost always made dry. Sauvignon Blanc tastes sharper because of its high acidity, while Chardonnay tastes rounder and softer because of riper fruit and oak. That roundness can feel like sweetness, but the sugar level in both is usually low.
Which is drier, Chardonnay or Sauvignon Blanc?
Sauvignon Blanc is the drier and crisper of the two on the palate, thanks to its higher acidity. Chardonnay is also dry, but its fuller body and softer acidity make it feel less sharp. If you want the cleanest, driest sip, choose Sauvignon Blanc.
Do more people drink Chardonnay or Sauvignon Blanc?
Chardonnay is the more widely planted and consumed of the two worldwide, partly because of its huge role in Champagne and white Burgundy. Sauvignon Blanc has grown fast in recent decades and is hugely popular in South Africa, New Zealand, and the Loire.
What temperature should I serve them at?
Serve Chardonnay around 10 to 13°C so its fruit and texture can show, with richer oaked styles best at the warmer end. Serve Sauvignon Blanc a little colder, around 7 to 9°C, to keep it crisp. Straight-from-the-fridge cold flattens flavour in both, so give the bottle ten minutes before pouring.
So, Chardonnay or Sauvignon Blanc?
Sauvignon Blanc is your crisp, zesty, food-lifting white for fresh and light meals, while Chardonnay is your rounder, fuller white for richer plates and colder evenings.
Both are dry, both are made beautifully in South Africa, and the only real way to find your favourite is to taste them together. Book a tasting or order a bottle of each and decide for yourself.
