Origin class: mixed (stated); fermented-product type: fermented beverage. status_condition: sugar-water fermented by kefir grains; ethanol content rises with fermentation time, so doubtful pending testing. Madhhab note: same trace-ethanol reasoning as kombucha; conservative doubtful. Aggregation methodology, not scholar-ratified.
