What You Need to Know
Involves dual fermentation: (1) Amylolysis via mold (Rhizopus oryzae) in starter cakes (ranu/balma), (2) Sequential LAB (Lactobacillus plantarum) and yeast conversion of sugars to lactic acid (0.3-0.7%) and ethanol (2-5% ABV). Contains bioactive peptides from rice protein hydrolysis.
Served as a cooling drink in earthen pots, often with ginger or chili for balance. Tribal versions use finger millet (ragi) for deeper umami. Critical in harvest festivals and Shamanic rituals.
