Kefir Soda Starter

Our Kefir Soda Starter is one of the best ways to have your soda and fizz without all the harmful additives and unhealthy sugars and sugar replacements. This soda contains beneficial bacteria strains and good yeasts to help you make a fun bubbly, and healthy replacement for soda! Each package can make you dozens of liters of kefir soda if you make it often.

The strains and yeasts metabolize the natural sugar found in fruit juice or coconut water, resulting in an effervescent drink that is loaded with probiotics.

Depending on the temperature in your home, it usually takes 3-5 days of fermentation for the first batch to reach your desired taste and fizz. You can use some of the resulting beverage as a starter for many subsequent batches. These will ferment more quickly in 1-2 days. Be careful it gets really fizzy!

Add your choice of flavor and spices to the basic recipe to make a range of fizzy drinks, fit for any occasion! See the included instructions for some fun recipes or check out more recipes here.

What You'll Get

  • 4 packages of Kefir Soda Starter
  • Instruction booklet with Recipes and FAQs

Important! Pop The Top Every Day

Make sure you use bottles such as Grolsch or thick glass bottles made for beer or brewing. Old GT's synergy kombucha bottles will work too. Bottles bought at craft stores can explode.

32-ounce Amber Bottles

32-ounce Clear Bottles

Then while fermenting, check them every day by slowly popping the top. After fermentation and they're in the fridge, pop the top every day to release the pressure as well. These can get a lot of pressure and are super bubbly. You'll want to check them often to release the pressure.

How to Make Kefir Soda With Our Starter

  • 2 cups  juice (fresh, frozen, or bottled )
  • 1 packet Kefir Soda Starter 
  • 2 cups water – Lightly filtered or spring


  1. Fill the rest of the bottle with water leaving an inch of room at the top.
  2. Allow it to ferment for 3-5 days or until bubbly and fizzy. If your home is 75°F or warmer, it will usually take  3-5 days.
  3. When it's done, place it in the fridge right away. You can pour into a glass and enjoy right away but keep it stored in the refrigerator or it will explode. Open the bottle often to release pressure. Consume within 1-2 weeks for the best flavor and most benefit.


You can use 1/2 cup of this finished kefir soda as a starter to make a new bottle. Add 1-3/4 cups  juice  and water and ferment again. It should only take half to a full day to ferment. Check it often!
