Avoid bottle bombsBottle only after the gravity reads the same 2–3 days in a row, measure priming sugar with a calculator, use standard bottles only to about 3 volumes, store them in a closed box at room temperature and refrigerate once carbonated.Source: BYO carbonation priming chart
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
