Sulfite-free wine: what it really means, and who it's for
No wine is completely free of sulphites. What “no added sulphites” means on a label, the rules in the US and EU, who should care, and what it does to the taste.

The short answer: there is no completely sulphite-free wine. Yeast make small amounts of sulphites during fermentation, so every wine has some. What you can buy is wine with no added sulphites. That matters if sulphites don't agree with you. For everyone else it is a question of style, not of how you will feel the next morning.
A note on spelling: Americans write sulfites, the British write sulphites. Same thing.
What sulphites do in wine
Sulphites are compounds of sulphur dioxide (SO2). Winemakers add them for two reasons: to protect the wine from oxygen, which turns it brown and flat, and from bacteria and wild yeasts that can spoil it. They are also used to preserve many foods, such as dried fruit and some soft drinks.
Red wines usually need less than whites, because their tannins also protect them. Sweet wines usually need more, because sugar feeds the microbes winemakers want to keep out.
What the label tells you
| On the label | Where | What it means |
|---|---|---|
| Contains sulfites | USA | 10 parts per million (ppm) or more of sulphur dioxide. Almost every wine says this. |
| No sulfites detected, or Contains less than 10 ppm sulfites | USA | The wine tested under 10 ppm in the government's own laboratory. |
| Sulfite free | USA | Not allowed on a US wine label at all. |
| Organic (USDA seal) | USA | No sulphites may be added. |
| Made with organic grapes | USA | Organic grapes, but sulphur dioxide may be added, up to 100 ppm. |
| Contains sulphites | UK and EU | More than 10 mg per litre, roughly the same as 10 ppm. |
| EU organic leaf logo | EU | Sulphites are allowed, but less than in conventional wine. |
| No added sulphites, sans sulfites ajoutés, senza solfiti aggiunti | Europe | None were added. Small natural amounts remain. |

The US rules are on the TTB's sulphite page. In France, a natural-wine charter called Vin Méthode Nature, recognised by the authorities in 2020, lets producers say “sans sulfites ajoutés” when they added none.
How much is allowed?
EU law sets a maximum for every wine, and the organic rules are stricter. For dry wines:
| Dry wine | Conventional (EU) | Organic (EU) |
|---|---|---|
| Red | 150 mg per litre | 100 mg per litre |
| White and rosé | 200 mg per litre | 150 mg per litre |
- Red
- Conventional (EU)150 mg per litre
- Organic (EU)100 mg per litre
- White and rosé
- Conventional (EU)200 mg per litre
- Organic (EU)150 mg per litre
Sweet wines are allowed more. These are maximums: many careful producers use far less.
Who should look for no added sulphites?
The NHS lists sulphites, found in cider, beer and wine, among the common causes of food intolerance. If you think you react to them, talk to a doctor rather than trusting a label, and remember that no wine is completely sulphite-free. I'm a sommelier, not a doctor.
Will it stop a headache or a hangover?
Don't count on it. A wine with no added sulphites still has all of its alcohol, and the alcohol is the same whatever the label says. Drinking less, more slowly, with food and with water does more for the next morning than any label. See how much wine gets you drunk and how much alcohol is in wine.
What changes in the glass
- At their best: vivid, juicy and alive. Many natural-wine lovers say they taste closer to the grape.
- More fragile: without that protection, a wine can turn flat, cidery or develop a “mousy” off-flavour that you notice at the back of the throat.
- Bottle to bottle, they vary more than conventional wines.
- Storage matters: keep them cool and away from light, and drink them young unless the producer says otherwise.
How I would choose one
- Look for the words above on the label, or the USDA Organic seal in the US.
- Buy from a shop that keeps its wines cool and knows the producers. Natural-wine shops often do.
- Start with a light red or a fresh white, which show this style at its best.
- Once open, finish it within a day or two.
Questions people ask
Is there any wine with no sulfites at all?
No. Yeast produce small amounts during fermentation. A wine can have no added sulphites, and in the US it can test below 10 ppm, but not zero.
Is organic wine sulfite-free?
Not always. In the US, “organic” wine may not have added sulphites, but wine “made with organic grapes” may contain up to 100 ppm. EU organic wine may contain sulphites, at lower maximums than conventional wine.
Does red or white wine have more sulfites?
Usually white and sweet wines. EU law allows dry whites up to 200 mg per litre and dry reds up to 150, because tannins help protect red wine.
Why does every US wine say “Contains sulfites”?
Because almost every wine has 10 ppm or more, which is the level that requires the statement.
