There is a drink sold in many stores near the other non-alcoholic drinks called kombucha. On the label, it says “due to fermentation, this may contain a trace amount of alcohol BELOW 0.5%”. According to the Sayed Sistani (may Allah prolong his life) website, it is permissible to eat food containing very minute amount of alcohol, e.g., 2%. Does that mean this kombucha is halal to drink or haram?
