  • ½ gallon fruit juice
  • ½ cup whey


  • ½ gallon steeped herbal tea or water
  • ¾ cup sugar
  • ½ cup whey
  • Lemon, lime, ginger, etc.


  • If using juice, simply combine the juice and whey in a half-gallon (2-L) jar. If using sweetened teas or water, steep the tea at a rate of 1 teaspoon (1 g) of herb per cup of water. Strain and add the sugar while still hot. Allow to cool before combining with the whey and other flavorings.
  • Seal the jar with a lid and allow to ferment for 2 to 6 days, depending on the temperature. Transfer the liquid to airtight bottles for a second fermentation of 1 to 3 days. Pour over ice and consume immediately or transfer to the refrigerator for 1 to 2 weeks.


  • For lemonade, use ½ cup fresh lemon juice with the sugar and water.
  • For a honey-sweetened version, replace the sugar with ½ cup raw honey.
  • For root beer, use ⅓ cup of Root Beer Syrup in combination with the sugar, whey and water.
