  • 1½ quart jar with airlock OR a 1½ quart jar with tight fitting lid
  • wooden or plastic spoon


  • 2 cups beets (rinsed and roughly chopped - no need to peel)
  • 2 tbsp fresh ginger (rinsed and roughly chopped - again, no need to peel. see what I mean about how easy this is?)
  • 4 cups filtered or spring water (chlorinated tap water inhibits fermentation)
  • 2 tsp unrefined sea salt


  • Thoroughly wash and dry your jar and lid before getting started. If you don't have a jar with an airlock, see the notes section for using a regular jar.
  • Place beets, ginger salt and water in jar. Stir with a wooden/plastic spoon until the salt is dissolved.
  • Close the jar and attach the airlock. Add water to seal it. (If you’re new to airlocks, I’ve included a tutorial below.)
  • Ferment at room temperature in a dark area. I usually place mine in a cabinet or wrap it in a towel. 
  • Allow the kvass to ferment for 3 days – two weeks. If I'm not in a rush I ferment mine for two weeks.
  • When the kvass is ready, strain the beets and set them aside. Pour the liquid into a clean jar with a tight fitting lid or swing top bottles and refrigerate until you're ready to use it.


Optional: Use the beets for one more ferment using the same recipe and 1/4 cup kvass as a starter, then discard them and start with fresh beets.* If you’re using a jar without an airlock you will need to “burp” your jars periodically, otherwise carbon dioxide levels can build up within your jar and create pressure. Check the metal lid every day – if you can’t push it down simply unscrew the lit a bit and then immediately tighten it back down. Using an airlock which allows the gases to release eliminates the need to burp your jars.
If You're Using A 1.5 Quart Jar Without An Airlock: 
Place all ingredients in your jar and stir to combine with a wooden spoon. Twist the lid on snugly and place in a dark area. Ferment for 3-5 days, then strain and store kvass in the fridge.
