                                Virtually no wine, including champagne, is ever truly 100% sulfite-free, as these compounds occur naturally during fermentation. The key distinction lies between naturally occurring sulfites and those added by winemakers as a preservative, a crucial point for anyone asking if champagne is sulfite free.
