Yes because champagne is made from grapes the same as wine. Wine, white and red, has naturally occurring sulfites as well as sulphites added to stabilize it. Champagne is likely to have as many sulphites as white wine. Red wine has fewer sulphites than white wine. Dry wines have fewer sulphites than sweeter wines and champagnes.
Sulphites are put into wine to stop the fermentation process.
As far as I know, the beverage that contains a lot of sulfites (sulphites) is wine where as beer or other distilled spirits or liqueurs will have less that that. Even if it did, in some countries if it passes a certain threshold, the manufacturer will be legally required to label "contains sulfites" on the container.
