But add just one more timeless summer flavor and create a drink that was the quintessential summer day companion: Strawberry Lemonade. We take fresh strawberries, lemon juice, and sugar and combine it with water kefir’s perfect blank canvas to make our new favorite drink come June, July, and August.

It’s important to note that brewing homemade water kefir is almost always a two-step fermentation process. Brewing water kefir is only a one-step process for those who prefer unflavored and mostly flat water kefir. Otherwise, the steps consist of a primary fermentation and secondary fermentation.

  1. Primary Fermentation: The primary fermentation is the first step of the water kefir brewing process. This is where your water kefir grains transform regular sugar water into the tart and slightly sweet water kefir we love. At the end of this stage, you will have finished water kefir, but it will be flat and, depending on the source of sugar used, unflavored.
  2. Secondary Fermentation: The secondary fermentation is the step where you bottle, carbonate, and flavor your water kefir by the addition of sugar and flavors. This step is essentially adding a bit of sugar/flavor to each airtight bottle and letting it ferment a little longer, allowing the yeast to carbonate the beverage in an airtight environment naturally.

Since this recipe is for the secondary fermentation, to make this recipe, you will need to have water kefir that has finished the primary fermentation and is ready to bottle.

  • Water Kefir: You need water kefir that has completed primary fermentation and is ready to bottle and flavor.
  • Strawberries: You can use fresh or frozen Strawberries. You’ll need 2-3 strawberries, quartered or pureed, per 16 fl oz bottle of water kefir.
  • Fresh Lemons: For each bottle, use 2 tbsp of lemon juice, then some to cut up for garnish (optional). Fresh lemon juice is tart and bright. It’s a great addition to any water kefir recipe but also plays well with other citrus fruits.
  • Sweetener: Brewer’s Choice! Use 1 tsp of the sweetener of your choice. We always recommend organic cane sugar for the purest and most refreshing flavors.


This recipe makes one 16 fluid ounce bottle. Before beginning this recipe, you will want to:

  1. Reserve your grains from your completed primary fermentation and set them aside. You will use these grains as your starter for your next batch of water kefir.
  2. With your water kefir grains placed aside, you will have all the finished water kefir separated and ready to bottle. These bottles are the most popular as they are considered the best bottles for water kefir secondary fermentation, but any other airtight bottles made for carbonation will work.

16 FL Oz Bottles



Prep time



Second Fermentation

1-3 Days

This strawberry lemonade water kefir recipe is for one 16 fluid ounce bottle. For a quart batch, make two bottles. To scale this recipe to a quart batch, multiply the ingredients by two or toggle the serving size up to two above. Before bottling your water kefir, remove the water kefir grains and reserve them for your next batch.


  • 16 Oz Water Kefir from a completed primary fermentation

  • 2-3 Strawberries

  • 2 tbsp Lemon Juice

  • 1 tsp Sweetener

  • 1 16 Oz Water Kefir Bottle(s)

  • Funnel

  • Measuring Spoons

  • Blender


  • You can either puree the strawberries in a high-speed blender or quarter them, all depending on whether you want the final product altogether or strained before drinking. We recommend testing out both ways to find out which one you prefer!
  • Place clean 16 oz bottle in the sink.
  • Add the prepped strawberries, lemon juice, and sweetener into each bottle.
  • Using a funnel, slowly pour Water Kefir into the bottles, ensuring there is about one inch of headspace left from the top of each bottle. The Water Kefir may foam up as you pour so be sure to pour carefully.
  • Tightly place caps on each bottle.
  • Keep bottles at room temperature for 1-3 days; it will carbonate faster at higher temperatures and slower when cold.
  • Burp the bottles as necessary to release excess pressure. This is done by removing the cap to allow built-up pressure to escape then placing the cap back on.
  • Chill in the refrigerator once you’re happy with the carbonation levels. Based on preference, you can serve as is or strain before drinking.


  • First-time brewers may find it helpful to substitute a glass bottle for a plastic bottle of equal size. Fill the plastic bottle as directed above, leaving 1-2 inches of empty headspace at the top. This plastic bottle will now be used as a pressure gauge. Once this bottle becomes rock solid, you will know the remaining are ready. This method can help prevent bottle bombs.
