What You Need to Know
During fermentation, lactic acid bacteria such as Lactobacillus plantarum convert fermentable sugars into lactic acid, lowering the pH to around 4.5–5.0. The acid hydrolyzes phytate complexes, freeing bound minerals and reducing anti‑nutritional factors. The process also generates flavor compounds that give ogi its characteristic sour taste.
