Grape Kefir Soda

Did you know that grapes are actually considered to be a berry? Seventy-two million tons of these berries are grown each year worldwide, But most of them are used to produce wine. I love to make kefir soda with grapes as it gets super bubbly and tastes so, so good! Check your bottles often while fermenting, and use good bottles made for brewing. It gets more bubbly each time you make a new bottle.

  • Add the Kefir soda Starter packet OR kefir whey to the juice in a glass bowl and stir until dissolved.
  • Fill the rest of the bottle with water leaving an inch of room at the top.
  • Allow it to ferment for 3-7 days or until bubbly and fizzy. If your home is 75°F or warmer, it will usually take 3-4 days. Colder homes can take 5 days or longer, but you'll need to check it by popping the top to see if it's getting fizzy. It will start to bubble out the top if it does.
  • When it's done, you can pour into a glass and enjoy right away or place it in the fridge.  Keep it stored in the fridge or it will continue to ferment and get overly fizzy and hard to pour. Burp daily and consume within 1-2 weeks for the best flavor and most benefits.
  • You can use ½ 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 on subsequent batches and you can make many bottles over and over again!
