Wine - Why not to worry [so much] about Sulfites
I love Wine, in small quantities....A glass after a fantastic meal wraps it up perfectly or an afternoon drink after a hard day's work makes me feel so much better. I am not one to finish the bottle in one sitting....Wine should be savored.
But like everything these days, I wonder if Wine is still healthy for you, with all the news about SULFITES so I did some research and here's what I found:
Why are sulfites in wine?
Very simply, sulfites are a preservative to wine, which is a volatile food product (ever open a wine and it’s bad by the next day?). Wineries have been using sulfur around wine for a long time, as far back as the Roman times.
Back in Roman times, winemakers would burn candles made of sulfur in empty wine containers (called Amphora) to keep the wines from turning to vinegar. Sulfur started to be used in winemaking (instead of just cleaning wine barrels) in the early 1900’s to stop bacteria and other yeasts from growing. It also helps in the extraction of pigments in wine, making red wines ‘redder’.
Some interesting facts about Sulfites and Wines:
- About 5-10% of people with Asthma have severe Sulfite Sensitivity and some of the reactions include body swelling and migraine headaches.
- Depending on the production method, style and color of the wine, the sulfites in wine ranged from no-added Sulphur (sulphur naturally occurs in the process of wine-making 10-40 parts per million (PPM). Added Sulfites can take it up to 350 PPM
- Many dry Red Wines have 50 PPM.
- Wines with more color need less sulfur than clear wines
- Wines with higher sugar content need more sulfur to prevent secondary fermentation of the sugar.
- Wines that are warmer in temperature releases free sulfur compounds (a sulfur smell you get at times when you open a bottle of wine). This can be fixed by decanting the wine or chilling it for 15 - 30 minutes.
- Interestingly, other food items have more sulfur in them and if you do not have a reaction to these, chances are Wine drinking should be okay for you (See the chart below)
Should I be concerned about sulfites in wine?
If you have sensitivity to foods, you should absolutely try to eliminate sulfites from your diet. Eliminating wine could be necessary. Perhaps start your sulfur witch hunt with the obvious culprits (like processed foods) before you write-off wine.

There's a fantastic little gadget call ULLO that can purify the wine by extracting the sulfites before you consume the wine....things are looking up. Learn more about Ullo here:
