If all goes well, the yeast wins, and the wine ferments as expected. Other times, if a bacteria is taking over, a winemaker might add a little sulfur dioxide to help the yeast. Each bottled wine has 20 ppm to 30 ppm sulfites. Helena winery, he notes. Sulfur dioxide is present in a lot of packaged foods. According to the USDA, dried apricots could contain more than ppm sulfur dioxide. Meanwhile, the standard amount of sulfites added to a bottle of biodynamic wine is only up to ppm.
Sulfites, also commonly called sulfur dioxide, are chemical compounds that contain the sulfite ion. They are found naturally in a variety of food sources, including black tea , peanuts, eggs, and fermented foods. In fact, these compounds are commonly added to soft drinks, juices, jams, jellies, sausages, and dried or pickled fruits and vegetables to slow spoilage and prevent discoloration 1. They are also used by winemakers to help minimize oxidation in wine and maintain its freshness.
Thanks to their antimicrobial properties, these compounds can also prevent bacterial growth to prolong the shelf life of wines and other products 2. Sulfites are a group of chemical compounds found naturally in some foods and added to others as a food preservative.
They are also often added to wine to prevent oxidation and maximize freshness. They are especially important in the winemaking process, in which they are used to improve taste, appearance, and shelf life 3. Some research also shows that these additives can help block the growth of bacteria to prevent contamination and spoilage 2. Additionally, certain types, such as potassium metabisulfite, are used to sanitize winemaking barrels and equipment 6.
Sulfites can help inhibit bacterial growth, prevent browning, and sanitize equipment used in wine production. Most people can safely consume the sulfites found in wine with minimal risk of adverse side effects. For those with asthma who are sensitive to these compounds, consuming them can irritate the respiratory tract 1. One study in 80 people with a history of wine-induced headaches found that consuming wine with a higher concentration of sulfites was linked to a greater risk of headaches 8.
However, several other compounds in wine, such as alcohol , histamine, tyramine, and flavonoids, may also contribute to symptoms 9. Other potential side effects of sulfites have been reported as well, including hives, swelling, stomach pain, diarrhea, and, in rare cases, anaphylaxis, a severe and potentially fatal allergic reaction 1.
Sometimes those people prefer white wine instead… Contrary to popular thought, red wines contain fewer sulfites than white wines, and sweeter wines contain more sulfites than drier ones. If you consume dried fruit snacks and feel fine afterward, you probably do not have a sulfite allergy, but obviously, if you experience frequent or severe headaches you should talk to your doctor… Cover image by Agne27 English Wikipedia [1] [ GFDL or CC-BY-SA About The Author.

While all wine contains some level of sulfites, the prevailing myth has been that red wine has more sulfites than white wine.
But the science doesn't hold. Sulfite levels depend on how the wine is made and how much sugar it has. When producing red wine, the juice has contact with the grape skins and seeds. This results in a higher amount of tannins , which act as a natural antioxidant that protects the wine from bacteria. As such, less sulfur dioxide is required.
By comparison, white wine ferments for a shorter time than red wine and the juice doesn't have contact with the grape skins. As a result, white wine tends to have more sugar than red wine, thereby attracting more bacteria.
And you know what that means: more sulfites are needed to halt these microbes from growing wild and ruining the wine. Still, there are always exceptions to the rule and not all white wines are high in sugar — dry brut and high-tannin white wines like Chardonnay are two such examples.
When it comes to sulfites, it's not simply a matter of red vs. And those are just the H's. The red wine headache is a common complaint attributed to sulfites. While there is some recent research that shows sulfite concentration in wine can induce headaches, there are other studies that indicate histamine is more likely the cause.
As it turns out, red wine has significantly more histamine than white wine.
