This ginger bug recipe is a natural probiotic starter made from fresh ginger, sugar, and water. Perfect for homemade sodas, ginger beer, and fermented beverages, this starter is easy to prepare, packed with healthy bacteria, and adds a tangy fizz to your drinks.

  • Total Time: 4–7 days (fermentation time)
  • Yield: 1 cup

Ingredients

Scale

Start Ginger Bug

  • 2 cups filtered or bottled spring water

  • 1 tablespoon organic ginger, chopped into ⅛-inch pieces (unpeeled)

  • 1 tablespoon organic raw cane sugar

For Daily Feeding

  • ¼ cup chopped organic ginger (divided over 57 days)

  • ¼ cup organic raw cane sugar (divided over 57 days)

Instructions

Step 1: Prep Ginger

  1. Wash fresh organic ginger under cold water and pat dry.

  2. Chop the ginger into small ⅛-inch pieces. Leave the skin on for natural yeast.

Step 2: Start Ginger Bug

  1. Pour 2 cups of filtered water into a one-quart glass jar.

  2. Add 1 tablespoon of chopped ginger and 1 tablespoon of raw cane sugar.

  3. Stir with a sterilized spoon until the sugar dissolves.

  4. Cover the jar with a breathable cotton cloth and secure with a rubber band.

  5. Leave the jar at room temperature, out of direct sunlight.

Step 3: Daily Feeding

  1. Every 24 hours, add 2 teaspoons of chopped ginger and 2 teaspoons of raw sugar to the jar.

  2. Stir and re-cover. Continue this feeding schedule for 4–7 days.

  3. Watch for bubbles, a slightly tangy aroma, and fizziness—signs your starter is active.

Step 4: Strain and Store

  1. Once active, strain the liquid into a clean jar.

  2. Discard the old ginger pieces.

  3. Replace any used liquid with an equal amount of water, 1 tablespoon chopped ginger, and 1 tablespoon sugar.

  4. Store the starter in the refrigerator and feed weekly.

Notes

  • Always use filtered or bottled water to avoid chlorine.

  • Organic ginger works best due to its natural yeast content.

  • If mold appears, discard and start over.

  • Don’t overfeed the bug—it needs time to digest sugar.
