Sulfites and sensitive guestsCampden tablets and potassium metabisulfite add sulfites. Commercial wine at 10 ppm or more must say “Contains sulfites”; home wine is not labeled, so tell sulfite-sensitive guests (often people with asthma).Source: TTB: sulfite declaration
Kombucha safetyFerment in food-grade glass or plastic, never ceramic, glazed earthenware or lead crystal. Check with a calibrated pH meter that it reaches 4.2 or lower (and not below 2.5); discard moldy SCOBYs. Extension services advise people who are pregnant, immunocompromised or prone to acidosis not to drink it; we don’t recommend homemade kombucha for children.Source: Virginia Tech FST-297; UGA Extension C1312; CDC MMWR 1995
