Lemon-Lime Kefir Soda

I came up with this recipe out of necessity. With an overabundance of fruit trees in my new backyard, I had to think of ways to use them. The presence of white grape juice in this recipe provides the sugar content needed for the cultures to consume and make probiotics! It doesn't hinder the citrus flavor and helps provide the fizz!


Lemon Lime Kefir Soda

  • 3/4 cup lemon juice 2 large lemons juiced
  • 1/4 cup lime juice2-3 key limes juiced
  • 1 cup white grape juice
  • 1 packet Milk Kefir Starter (CFH)Or 1/4 cup Kefir Whey
  • Waterlightly filtered or spring



  • Add the Milk Kefir Starter (CFH) packet OR kefir whey to your juice and stir till dissolved.
  • Add your lemon and limes and add to a 32 ounce bottle. A funnel helps. (Make sure you use bottles such as Grolsch or Bormioli thick glass bottles. Bottles bought at craft stores can explode.)
  • Fill the rest of the bottle with water leaving an inch of room at the top.
  • Allow it to ferment for 2-5 days or until bubbly and fizzy. If your home is 75°F or warmer it will take usually 3-4 days. Colder homes can take a week or longer but you'll need to check it by popping the top and see if it's getting fizzy. It will start to bubble out the top if it does.
  • When it's done, place it in the fridge right away. You can pour in a glass and enjoy right away but keep it stored in the fridge or it will explode. Consume within 1-2 weeks for the best flavor and most benefit.
  • You can use ⅓ cup of this finished kefir soda as a starter to make a new bottle. Add the other ingredients and ferment again. It should only take a half to a full day to ferment. It ferments faster and you can make many bottles over and over again!


Note: Always use bottles made for brewing.
