  • fermenter (a pickle jar with a lid) ~2 Liters
  • Grater
  • Airlock


  • 400 gm raw sweet potato washed, peeled and grated
  • 150 gm Jaggery or brown sugar
  • water


  • Add the grated sweet potato in your 2 Liter fermenter jar
  • mix jaggery and add water to create about 2 liters of mixture
  • Cover it with a cloth tied to the lid and wait for 2 days for fermentation to pick up speed.
  • Stir it every day to prevent mold formation and making sure the sugar dissolves and mixes well
  • After 2 days when it becomes bubbly. Taste it periodically to ensure it is not too tangy.
  • Filter with a cloth (chalni) and pour it in air tight bottles.
  • give another day or two for bottles to become carbonated. Then chill the bottles and serve.


Since sugar is fermented out, it is actually a low-calorie beverage.
You can add ginger and spices to taste.

    How does it ferment? Can we add some baker’s yeast or wine yeast?
