Grape Ginger Kefir Soda

Print Recipe Pin Recipe
Grape juice makes some of the best kefir soda. Make sure your grape juice contains real juice and doesn't have artificial sweeteners that are often hidden until you look at ingredients. It won't culture if there isn't enough sugar for the microbes to consume. And remember, the sugar isn't for you, it's for the microbes to consume, and you'll know they've been consumed because it will taste refreshingly tart. It's so good, you'll want to make a bunch of bottles. It's super easy after the first batch and only takes a day!
Servings: 32 ounces

Equipment

  • 32-ounce bottle Make sure you use thick glass bottles made for brewing. Craft store bottles will explode.

Ingredients

  • 1 packet Kefir Soda Starter – or ½ cup Kefir Whey
  • 2 cups Grape Juice – Make sure to use bottled store bought juice.
  • 1 inch piece of ginger root – cut in two small pieces so it fits in the bottle
  • Water, spring or filtered with minerals – lightly filtered or spring
  • 5 whole grapes, frozen – optional

Instructions

  • Add the Kefir Soda Starter packet OR kefir whey to your juice and stir till dissolved.
  • Add your grape juice and ginger to a 32-ounce bottle. Using a funnel makes it easier. (Make sure you use thick glass bottles such as Grolsch. 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 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 and see if it's getting fizzy. It will start to bubble out the top if it does.
  • When it's done, you can pour it into a glass and enjoy it right away or place it in the fridge. It will continue to ferment in the fridge, so burp it daily and consume it within 1-2 weeks for the most benefits and the best flavor.
  • I love to add frozen grapes to my glass before serving. It's optional but delicious and keeps it cold longer.

Re-Culturing From Your First Bottle

  • 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!
