How to Make Water Kefir Soda (Recipe)

It’s a probiotic… it’s a carbonated drink… it’s water kefir!

I started making this as part of my mission to get more probiotics in our diet and it has worked like a charm! The kids love it and ask for it each morning.

Water Kefir Culture

You will need one unusual ingredient for this recipe: water kefir cultures (also called water kefir grains). They aren’t really grains, but are a symbiotic colony of beneficial bacteria that create probiotics and enzymes during the process of breaking down natural sugar.

I got my water kefir grains from this family-owned company. You’ll also need…

Equipment Needed

• Glass jar (1 quart or half gallon)
• Wooden spoon for stirring (avoid metal)
• Towel, cheesecloth, or coffee filter to cover jar

Ingredients

• water kefir grains (hydrated)
• ¼ cup sugar (per quart of water, do not use honey)
• water (non-chlorinated and filtered)

Instructions

• In a half gallon size glass jar, dissolve the sugar in a small amount of hot water. If you plan on making the full half gallon you will need ½ cup of sugar. If you are only filling the jar halfway then you only need ¼ cup of sugar. 
• When the sugar is dissolved, fill the rest of the jar with cool filtered water and make sure the water is not warm. It must be at room temperature!
• Add the hydrated water kefir grains.
• Cover with a towel, cheesecloth, or coffee filter and rubber band to keep out insects and small children.
• Leave on the counter (preferably at 70-75°F) for 24-48 hours.
• After 48 hours, strain the water kefir grains through a bamboo or non-metal mesh strainer pouring the liquid into another container. I use a half gallon jar for the first process then strain into two quart size jars.
• Restart the process by dissolving more sugar in water, adding cool water, and adding the same kefir grains. 
• To make the water kefir carbonated, pour a couple ounces of fruit juice such as grape, pomegranate, apple, or cherry into the water kefir you just strained. I don’t recommend citrus for this part, as it makes stringy yeast-like things that are not tasty!
• Once you’ve added the juice, cover the jars tightly with an airtight lid and leave on the counter n additional 1-3 days before drinking or refrigerating.
• Repeat the process!

Notes

The longer you let your kefir ferment, the more sugar ferments out. So if you’re limiting carbs, I recommend fermenting for the full 48 hours. Don’t leave it longer than that though or it can starve the grains, which need sugar to live!

My Favorite Kefir Variations

• After the first fermentation, cap the water kefir without adding any juice and leave on the counter. After two days, put in refrigerator and add vanilla extract before drinking — tastes like cream soda!
• Add lemon juice and drink right after the first fermentation — tastes like lemonade!
• Do the second fermentation with grape, apple, cherry, or pomegranate for a fizzy fruit flavored soda.
• Add raisins or prune juice for the second fermentation — tastes like Dr. Pepper.
• Make a grape or berry flavored second fermentation and mix with iced herbal tea for a carbonated fruity iced tea drink.
• Add pineapple juice after the first fermentation, but drink right away — don’t allow to ferment or it gets slimy!
