Calories: 69kcal


  • Two 2 quart size mason jars with lids


  • 1 cup plain regular not Greek yogurt
  • 1-1/2 to 2 cups fresh berries blueberries, raspberries, blackberries, or a mix, washed
  • 4 cups pure or filtered water
  • 1/4 cup or less liquid from strained yogurt
  • 1 tbsp raw honey
  • 1/4 tsp sea salt
  • 1/2 Lime sliced
  • 4 fresh mint leaves


  • Place a coffee filter or double layer of cheesecloth inside a strainer. Place the strainer over a pot or bowl to catch the liquid. Spoon the yogurt into the filter and cover everything with plastic wrap. Place this in the refrigerator for 12 to 24 hours.*
  • Clean your mason jars with very hot water and soap. Rinse them well with hot water.
  • Place the berries, water, yogurt liquid, honey, and salt in equal quantities in the mason jars. Stir gently with a very clean wooden spoon to combine well. Add the mint leaves and lime slices to each jar.
  • Cover the jars with the lids and give a gentle shake to make sure everything is combined. Place the jars in a cool dark area of your kitchen.
  • You should start to see carbonation bubbles after 1 day. Release the lids and let a little air out. Do this daily for 5 days.
  • When your fruit starts to resemble that of “cooked” fruit and your brew is bubbling, open the lids and strain the juice into a pitcher, leaving the fruit behind. Place the juice in well-sealed bottles. A good choice is clean clear wine bottles with stoppers.
  • Leave the fermented fruit juice on your kitchen counter for another 1 to 3 days to build up more carbonation, or just store it in the refrigerator if you like where the carbonation level is.
  • Serve over ice with a mint leaf and a few fresh berries.


* The strained yogurt has the consistency of soft cheese. You can add some chopped chives to this and use as a topping just as you would sour cream. It is great on chilis, tacos, and soups.
