If you've ever had a headache after a glass of wine and blamed sulfites, you're not alone. "Sulfite free wine" is one of the most searched wine terms online, and the confusion around it is real. Here's what's actually going on.
Every wine contains sulfites
Sulfites (sulfur dioxide, SO2) are a natural byproduct of fermentation. Every wine on earth contains some. When a label says "contains sulfites," that's a legal disclosure required by the FDA for wines with more than 10 parts per million. It doesn't mean extra sulfites were added.
The real question isn't "does this wine have sulfites?" It's "were additional sulfites added during production?"
"No added sulfites" vs. "sulfite free"
Truly sulfite-free wine doesn't exist. But wines made with no added sulfites do. These wines rely entirely on careful winemaking (clean fruit, controlled fermentation, proper cellar hygiene) to stay stable without the insurance policy of added SO2.
Most conventional wines contain 50 to 150 ppm of total sulfites. A well-made organic wine with no added sulfites typically lands between 10 and 40 ppm, from fermentation alone.
Do sulfites actually cause headaches?
Probably not, for most people. Research from UC Davis and other institutions suggests that fewer than 1% of the population has a true sulfite sensitivity, and those individuals almost always have underlying asthma.
The headache you get from wine is more likely caused by histamines, tannins, or dehydration. Red wine contains far more histamines than white, which tracks with the common complaint that "red wine gives me headaches but white doesn't," even though red and white wines contain similar sulfite levels.
That said, many people report feeling better drinking wines with no added sulfites. Whether that's the sulfites, the overall cleaner farming, or something else entirely, the correlation is real enough that it's worth trying.
What to look for on the label
- "Made with organic grapes" (US label): may or may not have added sulfites
- "Organic wine" (US label): no added sulfites allowed
- EU organic certification: allows added sulfites up to 100 ppm (red) or 150 ppm (white), lower than conventional limits
- "No added sulfites" or "sans sulfites ajoutés": the clearest signal
Italian wines are particularly well-represented in the no-added-sulfites space. Italy's organic winemaking tradition runs deep, and many small producers have been farming without synthetic inputs for generations.
Brands that make wine with no added sulfites
A few producers we carry that skip added sulfites entirely:
- Gorgo (Veneto): Their entire range, from Pinot Grigio to Bardolino Superiore, is made with no added sulfites. The Pinot Grigio delle Venezie DOC ($20.90) is a good starting point.
- Fattoria Lavacchio (Tuscany): Their Puro PetNat Bianco ($32.90) is a natural sparkling wine, no added sulfites, minimal intervention.
Beyond our shelves, look for producers like Domaine Marcel Lapierre (Beaujolais), Frank Cornelissen (Etna), and Radikon (Friuli). The natural wine movement has made no-sulfite winemaking far more accessible than it was a decade ago.
