Myth #2: Red wine is higher in sulfites than white wine
Ironically, the exact opposite is likely to be true. Red wines tend to be higher in tannins than white wines. Tannins are polyphenols found in the skins, seeds, and stems of the grapes. They also act as antioxidants and preservatives so less sulfite is needed.
In fact, while European regulations allow up to 210 ppm sulfites in white wine, the limit for red wine is only 160 ppm.
Other factors that affect how much sulfite is needed are the residual sugar and the acidity of the wine. Dryer wines with more acid will tend to be lower in sulfites. Sweet wines and dessert wines, on the other hand, tend to be quite high in sulfites.
